I just took a trip into the mountains of Bristol VA. During that trip, my 2004 WJ 4.7l did the following
would jump rpms from about 2k to 2.3k when I would hit a bump doing 70
would not increase rpms when I hit the brake while cruising steady.
Would keep steady rpm at 80.
I stopped off at a shop and asked for a transmission flush. the gentlemen said that he didn't do that anymore, trannies would go bad shortly afterwards. He indicated that he thought it was a bad solenoid.
That follows, because if you hit the brakes, the torque convertor should unlock, right?
I'm a fair wrench, and am pretty sure I can drop the pan off and swap the solenoid. As far as I know, the tranny fluid has never been changed, nor the filters.

for info as well.
Anybody got any advice? I'm thinking I should just drop the pan, replace the filters, replace the solenoid and see what gives.
