Can anyone tell me what transmission fluid came in the manual GXP’s? Having work done on my car, but at a standstill until it can be determined for certain what trans fluid is in my car. Called GM and another source, getting conflicting information.
I appreciate all of the replies. Ended up contacting Tremec, who advised to use Dexron III or Mobil 1. Decided to go with the Mobil 1. I assumed a lot of the folks on this board have mods (I don’t) and take theirs to the track (also don’t), which may be why there are varied opinions as to what type to use. Thanks again!
