SRX Transmission Fluid Change

Ultimate 2022 · July 26, 2017

Please let me know if this in the wrong location, or move it if needed. We have a 2010 Cadillac SRX, and it is needing a transmission flush or change. Does anyone have this type of car, and can anyone tell me if I should go with a drain and fill or a flush? Also, if anyone has done this procedure before, is it an easy one?

What engine does it have in it? 2.8 or the 3.0? The transmissions are from different manufacturers for each engine on those and the procedures do vary.

It's a 3.0 with 87,000 miles

3.0 has the 6T70/75 GM unit. On the driver side half of the transmission towards the front of the vehicle there is a small bolt that sticks out of the case. That is the drain plug. Vehicle off, you should get 5-6 quarts out of there. I'd do it after it runs for a few minutes, then let it settle for a few minutes that way its warm and flows out good. Torque spec is 106 lb in.

To fill, there is a cap on the top of the transmission from under the hood. Screws more or less into the front cover of the transmission. Has a dipstick as well. I'd throw 4-5 quarts, and then drive it.

Before you check it and top off, shift the PRDNL a couple times, waiting 2-3 seconds between each shift. The fluid has to be at 180-200 F operating temp before checking, hence my recommendation to drive it. Or you can idle it for a bit with 800-1000rpm in park to heat it up.

You could have someone do it, up to you really. Filter isn't serviceable, requires teardown of trans.

Thank you! That helps a ton!
