I didn't feel like looking it up. I know dexron is ATF, but i have seen some std'* that use it as well on other boards.

I wish I had a manual...

I have not picked it up..but i know its ready.
GM dealership looked it up and said Dexron III

Along with the Specialty Transmission shop that does them all day thought
it was supposed to be Dexron III

WTF?

I will have it changed if I have to....but I am hearing from more then one source
that ATF is very common now adays in manual trans. ??

Some manuals DO use ATF, and some Isuzu FWD 5 speeds used 5W30 engine oil. Transmissions are something I personally think fluid recommendations should be strictly followed, I've seen what can happen otherwise! Good Luck!
