Re: 81 Chevy K10 ShortBed

So at this point in this trucks life the only things that haven't been rebuilt are the transmission and transfer case. Well after my last wheeling adventure, the transmission wasn't to happy with shifting and the torque converter is constantly unlocking and locking which makes the truck jerk violently. So I pulled the pan off and sure enough lots of metal shavings and burnt smelling fluid. I put new fluid in and it drives better but it is very lazy shifting and sometimes will slip. So on the 9th of April I'm dropping it off at a local transmission shop to get rebuilt. I also plan on buying a boat soon and don't want a questionable transmission far from home.

To top off a fresh rebuild, I ordered a deep transmission pan from B&M. Holds an extra 3 quarts of fluid, should be handy for when I'm towing in the future.

I painted the B&M logo black for some contrast, this is a VERY quality item the mill job is awesome.

Re: 81 Chevy K10 ShortBed

Got the truck back from the transmission shop and it shifts great and the converter locks when it should and I actually get better mpg now as a result. I have officially put 20,000 miles on the truck since the major overhaul I did 3 years ago. Everything is holding up great and just thought I would post my thoughts and opinions on my experience rebuilding this truck.

First off, try to do all the work you can possible. I say this because it seems like in this vintage (73-87) shops at least in my area don't seem to appreciate them and don't properly care for them when you take them in to get something done or fixed. For example, when I brought my truck to the transmission shop, the owner scratched my door and rocker panel. Also early on in my build I was stumped on my ignition switch and had a shop near me fix it and when they fixed it they did a poor job on finish work etc.

Secondly, try not to make everything perfect. This is especially difficult for me because it drives my ocd crazy lol. These trucks were not perfect from the factory, so don't sweat the small details if everything didn't come out perfect. A good example of this is go to a car show and if you look at the cars/trucks closely, most of them have imperfections here and there which in turn make me feel better about the overall quality of my truck.

Thirdly, Drive it! I built my truck to be driven, not be a trailer queen or garage queen. This kinda goes in part with the second thing I mentioned, but honestly if you're going to spend the time and money to fix up one of these trucks drive it, don't be afraid! At the end of the day if driving a square means bringing back memories from a younger you or if you are new to this vintage be happy with what you have accomplished and at least you're not driving a blob painted silver.

If I were to go back and do a couple of things over, I would have not done the detroit locker in the rear end, I should have just put a true trac. Another item I would have done different is I would have rather put a rubber floor mat in. The last item I would have done different is I should have swapped in a manual transmission instead of rebuilding the turbo 350 oh well maybe in the future.

Future? The only things I have planned for this truck is to swap my chrome window gaskets in and replace my rear glass and buy that dang steering column I have been talking about for about a year now haha. I also need to get the front driveshaft rebuilt as the slip yoke has play in it. Also going to eventually get the exhaust done.

Here is a list of everything I have done:
Motor, all accessories, radiator, fan clutch, motor mounts etc.
All new interior, rubber seals, glass, fatmat on the floor.
Front and rear axle completely rebuilt with lockers/posi, rear driveshaft rebuilt
Vintage air (one of the best upgrades)
New paint
New transmission

Good news is that all the pictures are back so any newcomers can look and enjoy. Bad news? I got screwed a little on the paint, the guy that did it isn't holding up to his end of the bargain and won't repaint the roof and fix a few spots. Touchy subject because he is my uncles worker of 20 years or something like that.... lets see what happens before I move.

Anyway enough rambling here are some pictures of my new general grabber x3's 35x 12.50 r15 these are a true 35" tire much better highway cruising now.

Re: 81 Chevy K10 ShortBed

Well guys its been a while since I have updated my build thread. I moved to Idaho back in August and have really been enjoying it here loving the cooler weather, less congestion and country lifestyle. Here is a pic hauling the U-haul trailer it weighs 2000 pounds empty and I had it full to the brim with heavy stuff and the bed was full of plants my guess was it weighed around 4500 pounds. The truck towed it fine and did great despite the 100 degree temperatures and 860 miles of driving I did in one day.


Unfortunately, I am having some issues with my truck since I have moved up here. When I was moving up here I got to Wells Nevada and while I was at my one of many fuel stops for the day I heard a faint knocking sound at idle but went away with any kind of rpm. I finally got to my new home in Idaho and did some investigating and the knocking sound only comes after driving it on the freeway and only while it is in gear. If I drive it around town there is no knocking sound. Now fast forward to the last few weeks and there is a big shudder when the converter locks up and now I can hear a grinding/vibration sound when driving around. The noise happens when it reaches a certain revolution like room room room if that makes any sense lol. I unplugged the electrical connection on the side of the trans and there is no shudder but there is still a grinding and vibration like I mentioned before. The trans was rebuilt earlier this year with a new lockup converter. The transmission shifts fine and the fluid looks nice bright red and clean no shavings etc. I know new parts can fail but I am at a loss here any ideas? Flexplate maybe?

Also, this might be unrelated but my starter has been turning over really slow sometimes and today when I was out it BARELY started the truck. So my question is could the flex plate be warped or cracked causing the starter to drag more and ultimately making all this noise. Other times it starts really quick like it normally does. Any advice would be appreciated.

Re: 81 Chevy K10 ShortBed

Congrats on the move! I’m spit-balling here, but maybe you smoked the lockup clutch in the torque converter? And it is hanging up when you’re starting the truck? In neutral (park) that might not make much drag. I feel your pain. My truck is back in the trans shop for another rebuild 15 months after the last one.

Re: 81 Chevy K10 ShortBed

A cracked flexplate can simulate a knock sound.


Might just start there.
