IT7 Tranny Question
Hi,
I just got a rebuilt 5-speed for our '79 IT7 racecar but I drained the fluid out and don't know what to replace it with. What weight/grade should I use? My Dad said it looked like gear oil but he wants to be sure about it.
Any fellow IT7 racers here?
Thanks in advance!

For the first gen tranny i've been told by some to use only a GL-4 lubricant, as the GL-5 lubes wear the syncros out faster. Personally I've always run MT-90 or Amsoil.
Your right SCCAIT7 this stuff gets too expensive. On my ITA car I just change it once a season.

Yes. It works fine for day to day use, and light drag use, but under heavy abuse the bearings don't last much.
ATF is basically 5W20 with friction modifiers.
Just did the final event of the year. This transmission has lasted all season, which is a first for me. I love Shockproof.
