Head check on a transmission fluid change M6

bootss · 04-16-2024, 01:19 PM

I'm going to change the fluid on my ZLE (M6). I have 4 quarts of GM Fluid 88861800 and a pump.

I plan to drain from the sensor and fill from the fill to 1/8th below the hole. A good way to measure this is full then remove 240ml

Am I missing anything here?

All sounds good. Alternatively, you can pump in 3 full bottles and then pump in an additional 12 oz (20 oz remaining in bottle) and that should get you to the same level of fluid in the trans, rather than pumping until overflowing and then removing.
