RE: t-5 tranny fluid

I have Mobil 1 synthetic ATF in mine and it shifts great. But... I wasn't really having any problems before either.

Dextron/Mercron III is factory, Mercron V is even better, never tried the gm synchomesh or royal purple.

RE: t-5 tranny fluid

I was just thinking of dumping that GM sychromesh fluid and trying something else.

ATFin a manual trans....k im lost....i thought it was the sametype of oilused forrear end that you put in manual trans....maybe im wrong but thats what i just thought

yes, you are wrong

ATF is the recommended fluid for Mustang T5's and alot of other late model manual transmissions.

It's the older transmissions you are thinking about Keek. Many, if not all the older stuff required gear oil.

RE: t-5 tranny fluid

synchomesh is my choice... im a former dsm guy and those mitsubishi trannys are junk!!! ive always ran synchomesh in those trannys and never had a problem... except launching a 450hp awd car with a stock tranny uausally never comes out good lol
