HELP! A904 skipping 2nd gear.

I bet you'll find the strut laying on the top of the valve body. If nothing is broken and you get things back in place and the band adjusted it'll be time to put the valve body back up in place. The accumulator and spring Poison mentioned can be a bugger sometimes. Apply Vaseline to the accumulator body and sealing ring and slide it in place. The Vaseline will hold it there while you bolt the valve body in place. You may also have to rotate the driveshaft a little to get the parking pawl rod to slip back in. Torque the valve body to 100 inch lbs
