fluid in a tremic 3550
 

whats up guys, the UPS guy just dropped off my 3550 gearbox, my question is could u use dextron III ATF for a substitute for the GM syncromesh fluid ? any feedback would great ! thanks guys

I would stick with the GM Syncomesh fluid. It's what Tremec recommends.

Just go down to your local GM dealer and buy some from the parts dept. It's about $11-$12 a quart.

I agree 100%
I even called several different dealers around my house and the price varied by a couple of bucks per quart!
Good Luck
