GM Original Equipment 10-4034 (88862624) Dexron LS 75W-90 Gear Oil - 32 oz

2011 CTS-V Coupe, 57k miles. Had the dreaded clutch moan (sounds like tires rubbing) at slow speed, cold diff, full wheel turning lock. Drained old fluid, stabbed in new fluid. Few tight u-turns both ways, moan gone. 5 stars.

It's exactly what car call for.

I bought this gear oil to replace the differential fluid on my 2018 Camaro SS and so far, so good! I mean it's OEM, so it better work! I had to buy a hand pump to get it flowing, but it was such an easy job, I think anyone can do it. The price seems to have gone up about $10 since I last bought it, but I think it's worth changing out if your car has never had it done before.

I was having issues with the differential making odd sounds on my Corvette. I read that replacing the older diff fluid with newer fluid should help. Most people also suggested using the ACDelco product over other products, particularly Corvette owners. It did take a little time to quiet things down and it was somewhat gradual with usage. I read that you need to get the new fluid worked through the system and that may take doing some slalom runs, faster turns, going in reverse, etc. Also to take it easy for the first 500 miles after changing the fluid, which I did. I am not sure exactly when, but within a couple days I stopped noticing the sounds it was making before changing the fluid. I am happy with the result.

This is the OE gear oil for the Camaro ZL1. No additive needed. The race prep supplement indicates you should change the rear gear oil at 500 and 1500 miles. When I did this at 500 miles on my 2022 ZL1 there were already a lot of metallic filings on the magnetic drain plug as the gears lapped themselves into a solid fit between mating surfaces. Completely normal. Also, make sure you note the drain and fill holes and ensure you can open the fill hole BEFORE you open the drain hole. Nothing worse than draining your oil and then finding out you can't refill it! These plugs are different than the coolant service ports. Do a little homework and identify them. Mine were on the driver's side for the fill and the bottom for the drain. Very easy process to drain and refill and if the car is level then the 1.2 liter capacity is the same as when it starts to come out the fill hole.

Stick with this OEM fluid. You’ll be happy that you did.

This product is for GM rear differential with limited slip feature. The ‘LS’ tag on the label denotes this.

This is the real thing and replaces the fluid originally required for the limited slip rear axle in a GM Quadrasteer truck.
