In Reply to: new tranny fluid leak? :( posted by David S. on May 27, 2002 at 18:24:45:

Last week I had the old tranny fluid replaced with Redline and was pleasantly surprised by the new ease with which the shifter worked. (no short shift kit installed). Now, after having a tranny mount and flex disc replaced - I smell burning tranny fluid and have a some garage floor staining. It had a weekend of fairly hard use autocrossing, but I smelled it prior to that. Any ideas?


There's a detent spring cover on the top/rear of the tranny that will leak. You can replace it with a sturdier one, but I do not know the part number. It has 3 humps on it and is held down by a couple of bolts.

Replacing the rear main seal can be a real PITA. You need a 30mm 12-point socket, not impact socket. Pry out the lock-tab. Use impact gun to remove the nut. Pull output flange. Remove old seal with a seal puller. Seat new seal about 1mm deeper than the old seal so it rides on a different section on the ouput flange.

Do not use picks to pull out the selector shaft seal. I broke two in there, but I got the metal pieces back out. You best bet is to keep prying on it with a good, small screwdriver. I knocked mine in a little on one side and pried it out from the other side. Careful not to gouge the selector shaft too much. Seat the new seal with a 14mm or 15mm deep-well socket. Be careful not to bend the seal during reinstallation. It's probably a good idea to have 2 of each seal, just in case something goes wrong. They're not expensive.

I use MT-90 in the 280 and MTL in other Getrags.
