This is similar to people who put a can of trans rebuilder in their transmission when it starts to slip. I always wondered why there were Transmission shops that fixed transmissions, if the can of trans builder worked, no need for transmission shops ?
So than I guess TransGo will be put out of business, if all a person has to do is turn the screw in 1/2 turn on the pressure switch......how do you fix that P01870 code ? this forum makes me laugh, Thanks a lot, keep it coming !!!!

I wrote this on the bathroom wall in one of my transmission shops.... 1/2 turn rebuild....

Re: 4L60e overhaul


I didn't like how the reverse drum seal went in but was in a hurry when I did it. So I pulled it back apart to check it for a cut or rolled seal. Didn't find anything wrong so I put it back together and stacked in the clutches and steels. I'm cheap so I just put some sand paper to the steels and gave them a cross hatch pattern and squirted em off with brake cleaner and some air. They were flat and dint have burn spots so I'm sure they'll be fine.
Then we moved on to the pump. Pulled it apart including the boost valve and torque converter valve.





I put in a sonnax purple slide spring with the stock inner spring in too. Swapped in some new rings. Inspected the slide, rotor, and vanes, cleaned it and inspected the pocket and reinstalled the pieces. Going back with a .500 boost valve with the orings on it and a spring that came in the sonnax lb1 kit. It is starting to take shape.

=======================================================================
The reverse input drum piston fits nice and tight with the lip seals as it gets installed. Again, the lip wizard will cut these seals if you are in a hurry. This build has been going on for how long now, no sense in hurrying when it comes to installing these seals.

Did you drill out the two orifices in the reverse input piston and install the two upgraded orifices into the piston ? This is part of the transgo shift kit for your 4L60E.

Re: 4L60e overhaul

What do the revised orifices do? I didn't get a shift kit, just the upgraded boost valve and springs. If it does something worth while I'd consider getting and doing this.

I did fool with the pump the other night.
Put the larger boost valve and spring in. this valve has the orings. It is a ten vane pump. And put a washer in the over pressure valve.

I called the guy who does my converters. Got a quote to cut, clean and upgrade to a good bearing, good clutch and braze the fins. Said he could have it done in a few days after I drop it off.

Re: 4L60e overhaul

I suggested a shift kit in a previous post and you replied with

"We are going to for go the transgo kit due to budgetary constraints."

Not real sure exactly what that meant with that sentence but why not put a Transgo shift kit in it while you have it tore down. 50 bucks..... Buy the shift kit and it will give you your answer to your question.

The boost valve is great but again, not the total answer to this transmission.

Like YoungPup mentioned, P01870 code ?

Why not do it right the first time, and turning the pressure switch screw is not the answer either but I understand most people do things cheap and wonder why after the fact why they have issues I get it, but no one can beat experience and knowledge. Its up to you if you want to listen.

Its like these posts on this forum on why the crank will not turn after installing the crank, how in the world did the person get to this point in the first place, do all the prechecks prior to installation you would never have the issue, no difference in the shift kit. But again, got to like these forums.

I have to add, the 1/2 turn rebuild is now on my bathroom wall too thats a classic.
Here I sit, trying to make it shift but only fa*ted. LOL!!!!!

Re: 4L60e overhaul

Fifty bux is fifty bux and I just wanted a reason to drop general grant in an item that wasn't in a stock trans that went 225k miles. I'm not going to spend fifty to find out. I am of the view that if you get the pressures up and control those pressures with new seals and gaskets it should go well.

The po1870 code seems to need a reemer and larger valve to get that spool in the vb back into tolerance. I didn't have that code so I'm not going to address it. If it ain't broke I'm not going to fix it.

Needless to say I'm cheap. I am not afraid to spend the coin, but I do need a reason. I talked to the guy who does our torque converters. He got me a price on rebuilding ours with a good bearing, good clutch and brazing the fins. Not the $68 reman that the local trans part house sells but not that cheap either.

Re: 4L60e overhaul

The Transgo shift kit comes with a new Converter regulator/isolator valve which works in a worn VB. GM and SRTA rebuilt VB's come with oversized valves which Transgo does provide a part number for a replacement valve in this case. The new valve that comes in the shift kit replaces all original equipment .441 diameter isolator and converter valves. No reamer is required when installing the Transgo isolator/converter regulator valves into the VB.

What type of Lockup plate does your TC Man install in your TC's ? The Transgo Converter regulator/isolator valves work with all lockup plates.

So when you install YOUR rebuilt transmission back into the vehicle and when the TC locks up and it has a bit of a shudder you can tell your TC man that his TC is bad. Right ?

Looks like you are installing a corvette servo, do you think this servo needs to match the accumulator in the VB. This accumulator is located in the VB next to the Pressure control switch, this accumulator housing bushing will have a code on the end of the housing (example: D,DX,R). This code will allow you to install the required spring/ OZ tension for the 2nd servo of choice.

Would you change your engine oil without changing the filter, I will not "rebuild" a 4L60E transmission without a transgo shift kit even in a vehicle with 225K miles. If it aint broke, than why did you pull the transmission out of the vehicle ? REDO or REBUILD, you make the choice.

Re: 4L60e overhaul

Good stuff. I do have white spring to go in the accumulator for the corvette servo. This isn't the pwm unit. It is a 94 so it is either on or off so I doubt it will "shudder". I'm not sure on the clutch apply plate for the converter but I've been dealing with this place/person for over twenty five yrs and my dad longer than that. I trust he will take care and use what works.

I'm not to.the vb yet and will address the loose valve if it presents itself.
As far as pulling it, It was pulled in the early 2000s and replaced with a wrecking yard unit with 105k miles and decent pink fluid. This trans went another 50k or so and quit shifting. Probably a solenoid but with a "core" to build the activity was on.

You saw the clutches. They looked the part of high mile pieces. Obviously they were slipping. Hence the larger servo and higher pressure to try to get that under control. It wont be a hot rod and Won't be making passes at the strip. Just has to carry itself and a trailer some days and I'm confident it will.
I'll check the eBay for a kit and see what it entails. Just seems like a band aid and a fifty dollar one at that.
I'm just a back yard DIY guy who does my own work for fun(and I just don't want to spend the money to have someone else do it). If I had to make good on a warranty for the knot heads out beating on stuff in sure I would see things more like you do.
What happened to the young pup fellow? No constructive criticism? I can take it. I'm of the view that these forums are to help others and I'm glad Mr cheveyretoreman is providing that. Thanks for taking the time to post.

Most likely YoungPup saw that you were from Texas, so he don't mess with Texas. Texas does it their way.

I think you got this all covered, sounds like you really do not need any more help.

Re: 4L60e overhaul

I'm just posting up what I am doing. I have no.problem taking in any and all suggestions and am certainly glad you have posted. Will I use them all? You posted it yourself in a hard headed individual from Texas. Yall ran the last one off and he did have mad skills and knowledge.

Either way thanks again for the input I will certainly think them over. I post o plenty of forums and have been called names but I don't let that hold me back. I just want the why when I spend my hard earned money.

Am I wrong when I suggest that without the pwm for the converter clutch it is either on or off? This seems pretty similar to the setup in the 2004r and the 700r4. If you provide decent pressure and don't try to lock it up at full throttle it should engage. And if it engages stay engaged until told to release by adding throttle angle or a vacuum drop. Am I way off? I like to know what things do. I can be over the top, I get that. It isn't personal.

Again thank you very much for the suggestions. Obviously they work for you. I just want to understand the magic in there that makes it so.

As far as the guy with the "tight" crank, kudos to him for getting out and doing. Checkbook hotrodders might fund a lot of business but i don't respect a guy who doesn't wrench on his stuff. Doesn't mean i don't like them or wont help them, just don't respect them. To me hot rodding ia about putting it together and making it work, no matter how many times or late nights and weekends it takes. And with YouTube, one can learn just about anything. We all started somewhere. And if everyone knew everything nothing would ever go wrong. I try to be a lifelong learner and hope to help others along the way.

WOW dude, not sure exactly what you are saying about running people off. I just indicated you got it covered and you do not need me to tell ya how to do your DIY job. thats it.

I BE DANG, All these years I was wrong, never knew the New seals and gaskets Controlled those pressures. Very interesting. Now got me going to youtube to make sure of this new technology break thru. Let me call my buddy over at Transgo and tell him the News. They goin outta biz, aint worth no fifty bux fify bux is fifty bux. now run me off too

I bet you are the life of the party. No input, no tech, just insults and such. Good thing you have your knowledge. Better than nothin'.

I am out wrenchin, having a good time, you on the other hand seem to have a poor attitude and no desire to share what you think you know. Why do you come you a site like this? Just to waste your time? It makes you feel better about yourself to insult others? You my friend, and I use the term friend loosely, are a sad individual.

And fifty bux is still fifty bux. The transgo folks and apparently you are in the businesses to make money. I get that. Guys like me don't support you. We do it on the cheap and save a little coin. You are butthurt. I get that. Tell you what, go back to whatever rock it is you crawled out from under and Ill not summon you to my thread again. It is painfully obvious you aren't interesting in helping anyone else.

I ask a simple question. What does it do? Neither of you have elaborated. Yall posted of a po1870 code. I didn't have that code and doubt it will because it isn't a pwm trans so the valve isn't constantly being shuttled through its bore. Neither of you went into that or denied my theory other than, this is the way we do it and any other way is wrong. I did do some homework on this trans. I did do some youtube vid watching. Didn't see anything on there that you produced to substantiate your position. Just you on here trying to big time me throwing out that you have a buddy at transgo.

When you have something to add, post it. Other wise I ask again, why do you waste your time here?

Re: 4L60e overhaul

What is your feedback why you fool with transmissions without installing a shift kit is the point. Now I ain’t here to tell you a dang thing about how you should fool with your core. Sounds like you already a cheap expurt and that’s just fine with me. No need to double down on that but when someone is trying to explain what a shift kit does you state it’s a band aid. Think what you want there texasT. I have helped lots of folks some just like you. One thing that I have learned from this. Can’t fix stupid

Re: 4L60e overhaul

My feed back is I like to do things and learn. Neither of you have explained why I need a "shift kit" other than I just do. I asked to explain why one would drill on the rev drum and install the different size offices. What does this help? Why are we changing the size? Does it increase the pressure of the rev piston? Are you increasing the clamping force? Give me a reason or I'm just thinking you don't known or just don't want to tell.

Physics tells us that increasing the pressure will apply the clutches quicker and with more force. That is why that fellow suggested upping the pressure switch with half a turn. I know that by putting a stiffer spring in the pump slide the pump will stay in a position to deliver more volume at a higher rpm. Volume and pressure are related. The larger boost valve also gives the pump the ability to provide larger pressure. I'm sure it is in the kit. If the trans has worn seals that can't make use of the pressure increase we aren't getting anywhere either. So yes an overhaul with new is in order, not just putting in a kit.

This gets us to the clearances. And why new bushings and shaft seals are also needed to control those pressures. Also have to set those shifting clutches and band up to apply and release at the right time to get the shift feel the user wants.

I don't need my stupid fixed. I know how to read, and learn. You just seem to want to spend on things you perceive you need. If you build ten of these units a month and spend that extra $50 on each one math sez that is $500. If you could accomplish the same thing for $30 or $20 you could be netting and extra $2-300 in those months. Or you could be doing more of them by lowering the price you charge, though that is going backwards unless you have a crew doing the actual labor.

Either way it is a hobby for me. Next up is a 4l80e for our other suburban. And a water pump on or k2500 pickup in there too. Then there is the gravely garden tractor I am goofing with. And the front end (bushings n ball joints) of the suburban this 4l60e is going in. I like to wrench and don't do it on a schedule because it is a hobby.

You really a math expurt. Thanks for the math lesson and all your expurt assumptions but you are way off. Good luck to you and enjoy your hobby. I think you have a future in teaching math at your local elementary school.

Re: 4L60e overhaul

Glad to share. Math is a great thing because it balances out al the way up the ladder to calculus.

Speaking of hobbies, you should look into one as you seem pretty high strung. Really not good for your health. A good diet and exercise would probably help you too.

But hey, either way I hope you are well and get a kick out of looking down on us "little" people from your ivory tower.

Re: 4L60e overhaul

So we are back at it. Even though not approved by all, hahaha. We had a difficulty with one of the rings and it didn't look like id want it to, so we pulled it and tried again. Unfortunately that didn't work out either. But that is no problem for a steeper like myself. I bought a whole bag of rings and when I couldn't find those I bought six more. Then I found those first ones. I'm not all that organized. It's a hobby, what can I say. So I boiled some water and heated the third try out. Got it on and have it clamped down. Yes, controlling the fluid and pressure is important. Those wings do a lot of it so we will "get it" right.
