nice how there is 3 different answers. I've even heard (in a different thread a while back) of using 5w-30 engine oil.

Mobil 1 ATF meets Dexron 3 standards.

5W30 works in the Isuzu. Just depends on the year, at some point GM specified syncromesh instead of 5w30. Kinda like how with all the auto's they specify Dexron VI now.

I've never tried 5w-30, but I have run Mobil1 90W and my Isuzu HATED it... I was on my way home with some synchromesh to swap it out that night and my input shaft literally fell apart inside the tranny.

I'm just going to stick with synchromesh from now on.

Paying someone to install parts and bragging about it being fast, is like watching someone bang your wife and being proud to raise their kids.
