I have an '06 Aero SC automatic tranny and when I'm in 5th gear going about 45-50 mph and lightly accelerate my car jumps and it feels like the transmission is slipping. Does anyone have any insight into this problem or experienced this problem?

Well the valve bodies have issues but that is mostly in the shifting under heavy throttle such as doing 50-60 mph then in downshifting to 3 or 4. The solenoids stick and the bucks like a bronco not going into the lower gear.

Your situation might be different. Do you have the proper fluid in there and has it been changed?

Here's a link to the common issue.

has anyone changed the gearbox oils......sometimes this creates problems with the valves getting air in them which can seriously wreck an auto box.
