Did you see the video on the news of the 4 mountain lions on the jogging trail in Boulder, need more of them.

Re: 1972 C10 2wd M20 wont go into gear
 

Yes, especially since they want to ban semi auto rifles. Maybe after a few get eaten, they will think otherwise.

Okay here is a picture or two the white charging cord is towards the seat.

Re: 1972 C10 2wd M20 wont go into gear
 

if I'm seeing it right it looks jammed...take a big screwdriver and get all 3 shifters lined up...you'll have to pry em into place...

Re: 1972 C10 2wd M20 wont go into gear
 

Man I can't even tell what you're talking about from that picture I need to find some normal pictures along and go back to look at that thread.

What this happened because there was not oil in it?

Re: 1972 C10 2wd M20 wont go into gear
 

if you look down in the shifter hole you'll see 3 notched shift levers...they should all be lined up...here's a pic of a clean one so you can see em better...but this pic is in gear...

Re: 1972 C10 2wd M20 wont go into gear
 

are you saying the trans didn't have any oil in it? if that's the case you may have serious issues...

Re: 1972 C10 2wd M20 wont go into gear
 

Not 100% sure of level. Does not leak or drip. 90k miles so i did not stress about it. Had many other projects on the truck since july.

Here is a video in my google drive. See if it works.

What is that button or Rod looking thing on the left in my picture?

Re: 1972 C10 2wd M20 wont go into gear
 

What does the bottom of your shifter look like? Please post a pic. Your shifter has a small button on the bottom that goes in those slots. All the slots need to be aligned to be in neutral. The "Button" Should move freely between 3 aligned slots when in neutral if I remember right. Start with aligning that one on the right with the one in the middle.

Re: 1972 C10 2wd M20 wont go into gear
 

I can't tell what that is in the pic...lotta glare...and grease/oil....make sure its not the end of your shift rod broke off...

Re: 1972 C10 2wd M20 wont go into gear
 

Yeah when I initially pull the shifter out, I thought about that tab. I was not sure if I was hopeful that it was broken off so if he needs a fix or what. But it appears to be there.

Re: 1972 C10 2wd M20 wont go into gear
 

How hard was it to remove the shifter? It could have just come loose and raised up enough to come out of the slots. Could just need some work to the shifter.

Re: 1972 C10 2wd M20 wont go into gear
 

For some reason is telling me the security token will not let me upload a picture of the shifter. It has the little T on the end that I see on new shifter. Shifter came right out once I took off the lock ring with channel locks.

Re: 1972 C10 2wd M20 wont go into gear
 

Sound like it could be ok. Is the piece that goes into the slots at the end loose?

Re: 1972 C10 2wd M20 wont go into gear
 

Now it seems fine looks like it's Walden Honor made part of the rod itself if memory serves correct. I'm just trying to figure out how I'm going to crawl up underneath there with enough light and enough space for a screwdriver and my face to see down inside there to line up those shifting rails

Re: 1972 C10 2wd M20 wont go into gear
 

It's not too hard. Go for it.

Re: 1972 C10 2wd M20 wont go into gear
 

So when I get these shift rails all aligned my transmission will go back to shifting normally?

Re: 1972 C10 2wd M20 wont go into gear
 

can't say for sure but its one step in the process....

Re: 1972 C10 2wd M20 wont go into gear
 

This is a great chance to swap in an actual M20 like I did when my sm465 went out. The sm sucks anyways.

Re: 1972 C10 2wd M20 wont go into gear
 

I have an M20 for sale if you are interested.

Re: 1972 C10 2wd M20 wont go into gear
 

After many attempts to try and use my phone to take video with the flash on so i could see, i got those things aligned an am running again!

Sorry for the delays between post trying to coordinate between jobs and 4H and everything else. I now need a chiropractor appointment for crawling up underneath there at the same time.

My question is why does it do that? How does he jump out like that?:metal:

Re: 1972 C10 2wd M20 wont go into gear
 

glad that was your problem and its fixed....its just one of those things that happens sometimes....

Re: 1972 C10 2wd M20 wont go into gear
 

My guess is wear on the shifter. It is held in by spring loaded force. We know how to fix your problem because we have been there and done that. The first time I pulled a SM420 I got 7 stitches. A good chiropractor is nice to have. Push down real hard on your shifter in neutral and see if it moves down any . This "play" can be the issue. You may have a worn out ball and socket on the pivot of your shifter. Good to hear you did not have to pull it! Happy motoring!
