Re: 4L80E & TH400 Tech.
Why use 3rd party hosting when photos can be uploaded to this site directly?

Too bad, because this thread is great. I'll see if I can find an archived copy on the internets to save as a pdf. It looks like the photos are still on photobucket but embedded img tags are blocked... I already didn't like photobucket but this is ridiculous. imgur.com is free, fast, and has none of that nonsense fwiw.

Re: 4L80E & TH400 Tech.
Okay guys, quick question. I've got a 4l80e in my 03 2500hd, the converter locks fine around town, until you're on the highway and then it will unlock after about 73mph. I read somewhere that the pcm sends a ground signal to the tcc solenoid. Is this correct?

Re: 4L80E & TH400 Tech.
His thread was very helpful glad I was able to get answers to my questions before he left. Ill leave the transmissions to pro next time took to many hours to figure everything out ill just take it to a shop. Problem is not too many shops here do mods mostly just stock rebuilds.
Looks like he stopped posting here back in 2017. I saw a post from him on other forums seems to still be around not here. Last edited by kell490; 02-19-2019 at 12:34 AM. |

Re: 4L80E & TH400 Tech.
I just google searched his name. If you go to this forum yellowbullet there is a guy named Hutch he is an expert on transmission builds has a sub-forum there. You probably search / post over there find out lot of good information also if you can't find Clinebarger.

Re: 4L80E & TH400 Tech.
Is clinebarger still active here?
Did a 4l80 in my 73 and the tailshaft won't stop leaking 2 bushings 3 seals and all I've made it do is leak worse.

Re: 4L80E & TH400 Tech.
Google 4l80e rear seal and bushing issues. I believe there were two different bushings used over the years. Something like 40 or 50 thousands difference on the inside diameter.

Re: 4L80E & TH400 Tech.
It looks like your driveshaft may be too long. The slip yoke should not go all the way into the tailshaft on the transmission. It should stick out about 3/4 to 1 inch.
