GM Dexron VI, or castrol equivalent if you can't find it, and NO additives. No lucas, nothing...

Thanks for reply. Its shifting between third and fourth constantly till its warmed up. Figured it might help. Think i should just start with drain/fill first with no additive?

i've never heard anything good from transmission additives at all, but just in general, as picky as the tranny in these GAs are, I'm half scared to open mine at all, there is no way in hell i'd put anything other than tranny fluid in it. ever.

Lucas should ONLY be used as a last resort before a rebuild, but by the sound of it, a drain and refill with a filter change should do you well.

Use it. Castrol makes quaility oil and trans fluid.

Yes, that would work fine. When the new Dexron VI came out GM was the only one that had it, but most oil companies have there own now that meets the same specs. The new stuff meets much higher technical specs and requirements, and is a major step up from the Dexron IV.

Your clutch packs are probably worn out. Adding things is not going to help that. It needs to be replaced or rebuilt.

Thats what i was thinking. Im just hoping being it only does it when cold, the lucas stuff might help. Nothing to lose at this point i guess;crap
