anyone have part numbers? tips on removal/installation? truck has 142k on it an the trans hasn't been serviced so i'm planning on changing the filters an draining the fluid an putting in new. should it be flushed? wouldn't that cause problems being higher mileage?

 

also curious if continuing to drive it will cause any damage to the hybrid 1 and 2 clutches

 

pic of the truck. 09 sierra 4wd. I put a 4/7 drop on it and decladded stock gmc 20s an had them powder coated

 

Apparently its a restricted part from gm. They want to run several tests before they can approve of it be a bad pump

 

decided to check the codes since it was working properly. no p2797 but had a p0ac4 code.
