Ok, so I have a very hard shift from park to drive and reverse but mostly goes away once it gets to normal operating temp. Also a hard 1-2 shift all the time and feels sluggish in 1st gear. So far I've tried a new tps, a new epc solenoid, cleaned maf sensor and changed the tranny fluid and filter. Nothing has helped so far. What should I look into next? A whole new valve body?

 

I would suspect a failing acumlating Piston in the valve body

 

Thanks for the reply, i was thinking about that myself. I wish i had put a drain plug on the pan when i had it off.

 

Today i changed the 1-2 accumulator and put in a sonnax pinless forward accumulator piston. The 1-2 shift feels better but still clunks into drive. Do i need to unhook the battery to reset the computer?
