🔧 ACDelco GM Original Equipment 10-4033 75W-90 Manual Transmission and Transfer Case Fluid - 1 qt: Optimal Performance for Your GM Vehicle Review

This product has no viscosity for use in a manual transmission. The description says it is a high viscosity oil but upon opening one of the bottles I found that it is very thin and a reddish color very similar to ATF. I would not use this product in a manual transmission. I can't return the item as it has been opened, don't fall for the bad publicity.

Misrepresented product. It is listed as 75W-90 for a manual transmission but it is not. It doesn't say 75W-90 anywhere on the bottle, I opened one of the three bottles I received. The viscosity was thin and pourable, similar to an automatic transmission oil. 75W-90 should be a thick liquid, thicker than motor oil. I don't know what the actual viscosity of the fluid claimed is, but it's not 75W-90. Because I opened a bottle, they didn't refund the purchase price. Don't be fooled by a…

I did a lot of research and found that just because they are from the same manufacturer and have the same number of gears, not all Tremec transmissions are the same.

They said their computer showed the correct part, made by AC Delco, part…

Not much to say about the oil. It would be nice if they just shipped ones like gear lube with a cap with a tipped point to install since you don't spill anything. Luckily I have a lot of these in stock.

GM recommended fluid for T56, I've used it on several different six speeds and it's always worked great. Not synthetic, so works with both paper and carbon blocking rings. Cold weather performance is still chunky, but much better than some other liquids I've tried. Highly recommended and Revain has always had the best price I could find.

This oil was recommended by the dealer for my 2002 GMC Yukon Denali transfer case and works great. Tried an Autozone transfer case which was a bad idea and burned it would recommend this oil, pretty cheap on Amazon compared to dealer price, cost me 2 1/2 liters last year, 207k+ miles is great for the money compared to retail price
