Hello, I hope all is well out there in the First Gen Cummins Diesel World... It has been a while since I have been here... I have a few questions

I just had my ausomatic transmission rebuilt in my 1992 4x4 about 6 months ago. Lately It has had a problem staying in overdrive, and one of the last times it acted up like this i was cruising 65mph, no load, low turbo psi at around 4lbs and it down shifted into 3d. Top speed in that gear is about 55mph..

Anyway i brought it back to the shop and it didnt act up on them, but they said it might be a TTS sensor which can cause the tranny to shift like I mentioned? The shop called around and they could not find the part, they said the part is no longer made?

Well, I'm looking for one! Or any opinions of what would make my tranny do what it is doing..It happens more frequently now. The trany is under warrenty.

Thanks for any help! I made a video of the problem, please take a look! By the way...I have a full tank of diesel, the sending unit is out.

Have you tried adjusting the TPS?

Thanks, I'll ask the guys in the tranny shop!
I'm not sure where it is and how to adjust it!
