Automatic transmission shuddering on shifting what is the possible cause or causes?
One mechanic says diagnostic said solenoid bad. Another said valves warped.
Valves are pistons. What IS going on?
Pray that it's the solenoid. I believe that can be fix without pulling the transmission.
I would try a transmission flush before you spend the big bucks. I've seen it work wonders. I HIGHLY recommend BG brand flush fluids.
