Which fluid does everyone use? I know you can't use the older style fluid in new transmissions, but what can you use? What does GM use?
I really don't want to go synthetic, too expensive and have heard bad things about clutches slipping and mine are already on the way out. I just want to drop the pan, change the filter and top it off to see if it helps my transmission problems.
thanks guys.

 

I just used pennzoil Dexron III in mine. I discovered my tranny was about a quart low and i guess had been since I bought it new. I think most fluid brands are ok as long as they are the right type.

 

Anything qualified for Dextron III would be fine.

 

Thanks for the feedback guys.

 

I've been using Walmart brand, Supertech I think, since I got the truck with 17k. 100k later and the little 4L60E is still going strong even with a 6.0 in front of it and I rag on it all the time.

 

lol nice.. ya i use dextron III.. i wouldnt change to synthetic.. i heard that the fluid that you have been using creates a glaze over major componets of the tranny and when other types of fluids are used that it may ruin the transmission.. may be a myth.. but ppl have told me they've seen it happen.
