Wonder what I was thinking?

Friend had this for sale for $400.00 last night. I said, I'll give you $125. He said, where's your truck. Only a couple of years use but his driver had a heavy load and pulled a trailer in OD and now it slips in 4th. It's a good wrench replacement on a 1991 one ton. He said the original ran over 20 years and finally replaced it couple of years ago. Let one of his drivers use it to move and burned it up. Early model but GM updated to the newer internals for that case. I'm hoping some clutches and a TransGo HD reprogram will fix it up.

Easy fix. Good core price. When I purchased my last Chevy truck new, I read the owners manual. That thing says you can tow in overdrive. ?????? Really? Go ahead, you better have a light load, flat ground, and a good warranty. I wanted to do it just to burn it up. That way I could go in and say GM said this was ok.

I would contact Jakes performance in Texas all he does is 4l80e transmissions. I went through him for a rebuild kit I used in a 4l80 I rebuilt. He doesn’t use the transgo reprogram kit but gives you the instructions to do the same thing internally without having to spend the money on a kit and it worked well for me. I will see if I can find my instructions again if your interested.

Is it something you can email?

Once I find them I could make a copy and mail them if you like.

I have been told that the HD versions of those have straight cut planetaries that fit into TH400s.

These transmissions are basicly th-400's with overdrive added.
