I was in bumper to bumper traffic this afternoon for a 45 mins when the temp started to creep up over 200. I find a parking spot but needed to unload the car first before getting in the spot, about 5 mins later I go to put the car into reverse and feel nothing. Car seems to be stuck in park. We go eat and get back to the car. starts right up and goes into gear. I go to the auto parts store (I'm 54 miles from home) to check the fluid level and add fluid. It is not low.
I put the car into reverse and the car is stuck in park again! I let it cool and it is still stuck in park Shifter moves freely. I rock the car back and forth a couple times and cycle the shifter. It breaks loose. I start the car and put it into reverse, it does go into gear but will not shift into any other gear except park and once in park it is stuck there again.
Anyone have any ideas where to look before I tear into it? Valve body?
