Rear dif oil change convertible

Johnny Camaro · 06-21-2024, 02:27 PM

Hi guys I want to change my rear dif oil (2019 ZL1 Vert) but as you guys know the convertibles have a different a dif then the coups.
So my question is do I still use the same oil ? Dexron LS gear oil GM 88862624 or do I need other oil?

At the same time having it on the lift already I want to do my transmission oil as well. I saw multiple vids on YT but most of them are ZL1 LE are those the same 10A Speed tranny as in a regular ZL1?

I also see some do some don't change out the filter what do you guys do?

One guy brought the temp up first by letting the motor run for a while before he poured in the oil is that something you guys did to? He also made a big point of perfectly leveling his ZL1 LE, isn't the car leveled enough on a 2 post lift?

The A10 is the exact same in all ZL1s. The video you saw is correct on how to correctly do it. You have to bring it up to a certain temp, check the level by trying to drain any fluid out.

I hate it that GM went this route but it is what it is.
