have 06 uplander. transmision jerking in/out of gear when at stop light and on acceleration . changed trans. oil and filter,but didn't help. found problem was bad spark plug wires shorting to engine bock on occasion.it was draining enouph power to affect transmision solenoids .moral of story is .....make sure your vehicle is tuned up before you decide to have any major drivetrain work done.
