TF904 rebuilding tips or tricks?


Recommended Posts

I guess it depends on your level of mechanical ability, but you may want to find someone who has experience with auto's to help you with it. There are parts under spring pressure where you will need special compressors to safely remove and install snap rings. Various seals need special care to ensure that they are not damaged during installation and depending on mileage, you may have wear in bushings and planetary sets that need to be checked. The last thing you want to do is spend a couple of days on this and have the trans in worse shape than when you started. At the very least find a quality manual for doing an overhaul, not just some Chiltons guide.

This is not my first rodeo...

Just seeing if anyone had any tricks, I know how to change shift firmness on a TH trans with a drill bit, seeing if there is anything similar on the TF trannies

I meant no insult there. You give no indication on your mechanical ability. You can mess with VB springs, accumulator springs, line pressure and gov pressure if you want to to improve shift firmness and make it a bit more snappy. Is this bolted up to a 2.8? If so, then there is little to be gained by messing with the trans.
