[saniutza]

i have a Tremec 3550 with about 10k miles.... was leaking before after i rebuilded the engine, changed the rear main seal i think it's called and now it's still leaking... somebody was saying there's a seal inside... anybody has a clue what's that seal called??? i would like to go and buy one to change it and i don't know how it's called... i looked in the repair manual but doesn't say anything about any seals inside or how to change it... tnx

There is a seal on the input shaft and another on the tailshaft housing for the drive shaft yoke. Which one are you talking about?

The Tremec rebuild kit I bought was $384, it included syncros and all the bearings. There were no shims in the kit, and you will need them to assemble the trans with proper preload on the roller bearings for the main shaft and countershaft.

There is a video on how to rebuild your T5 or Tremec 3550. If http://www.hanlonmotorsports.com/ are out of stock see http://cartapes.com. It costs less than $20, and is worth every penny of it.

i attached a pic with the seal that it has been changed... i think it's the tailshaft housing seal.... i'm pretty sure i don't ahve to rebuild it because i don't have any grinmding or anything... it's just leaking from this rear seal...

because this seal was changed what could make it still to leak???

btw tnx a lot for all the info

The seal on the talshaft will leak if the yoke is worn. Remove the driveshaft and carefully inspect the yoke. There may be a groove worn in the yoke or other damage.

Can leaving a leaking/seeping seal in there (auto or manual) for a while cause any damage to the driveshaft?
