    Dexron VI in a Manual Transmission

    can anyone tell me why you CANNOT run dexron VI in my 2002 trans am with a 6 speed manual? Why is Dexron III allowed and Dexron VI isn't?

    this is my educated guess..becuase there is a formula change with VI over III..so the gaskets, and everything else is designed to work with III but VI might eat or degrade gaskets and so forth very fast.

    i put the dexron VI in mine and put on maybe 50 kms and read that it is a no no, so i dumped the oil last night and let it drip over night. i will be filling it up with gm's manual tranny oil tonight.

    A GM Service Bulletin says the following:
    Quote Originally Posted by GM

Dexron VI is also compatible with any former version of Dexron for use in automatic transmissions/transaxles.

    Dexron III must not be used in place of Dexron VI in models that specifically call for the use of Dexron VI, fluid and component life will be compromised.

    The content of this bulletin does not apply to manual transmissions or transfer cases. Any vehicle that previously required DEXRONģ-III for a manual transmission or transfer case should now use P/N 88861800. This fluid is labeled Manual Transmission and Transfer Case Fluid. Power Steering Systems should now use P/N 9985010 labeled Power Steering Fluid.

    dex vI (88861003) is not allowed in manual transmissions or power steering thats what the back of the gm dex vI bottle says. I went to the dealer yesterday use part # 88861800 its called manual tranmission and transfer case fluid it was $30.72 for 4qts. Thats the part # number alldata revised also
