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.

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.
Ah, ok. The one pic showed the yoke all the way in.
