I just started adding fluid to my New Pro-built Tranny and I have a leak, but its not coming from the pan. From what I can see its from the TV Cable area, I let the tranny down as far as possible but cannot pinpoint location, but like I said its building up behind the backside of the TV Cable. I have tighten down on the one screw that hooks the TV cable to the tranny and its still leaking most of all im loosing my Pro-Built fluid. Can somebody give me any suggestion on how to stop this leak? I DO NOT think it has anything to do with PRO-Built Transmission. Just want to make that CLEAR. Maybe there is a gasket that goes under the TV Cable to Tranny or I should have put some permatex to help keep the seal. Need help Quick.
Thanks: David

 

since your in a hurry- my th350 did that. it was the filler tube it neededa newrubber and the kickdown needed an o ring. drain your fluid and check them before you make abig mess like i did.

 

it would help to know what kind of tranny your refering to.. have you checked the gasket around your filler tube? cooler lines?

 

Its a 700R4, its not leaking from the filler tube or cooler lines. Its coming from TV Cable area. Maybe its missing the o-ring I will have to take it loose and see. Rest assure it not the cooling lines or Filler tube.

 

There is a rubber seal that goes around the TV Cable housing. Its possible that it got damaged when you installed the TV Cable.

 

most likely its missing oring, my th350 leaked like a siv after i did the swap, dropped it, looked at the tv cable and it didnt have an oring, put an oring on, its as water tight as a frogs *** now
