Just got the car back from the shop and I have a very delayed and then hard shift into 2nd gear. I remember reading something about a sticking accumulator piston (i think?) causing this issue. FWIW, right before I made it back home after the accident Sunday, the O/D light started to flash. I'm assuming this was due to the lost fluid which caused the remaining to overheat? Tranny has like 20,000 miles on it and had no issues before my accident.
