Is it worth doing it half-arsed? It's a flush because there are parts of the gearbox containing old oil that wont be drained unless you're flushing it with new oil while shifting through R N D or something like that.you can DIY with a drain and refill.
They didn't flush it, but I'm still having issues with it. They found a bad axle and engine pads (ie: motor mounts) so they just flashed the trans software stopped there. But the deep trembling (best word I can use) is still there at certain speeds and RPMs in certain gears. I am bringing it back in after a family trip next week, and will demand that they flush the torque converter and trans. They didn't even look at the fluid to see what color it was or what condition it was in.Thanks, it makes sense what you say. Any other mechanics with some advise on the issue. To flush or not...
T5forLife said he would ask/consider... Any news?
