hi
im getting p1810 so i read most of old treads but not clear. i put a new pressure switch about a year when the valve body was rebuilt. so do i need to change the pressure switch only again? or does the valve body need something again? also im getting hard engagement when puting it into drive or reverse to. and reverse engages way to fast while drive is slow. is that a manual valve link agajustment? and the tcc locks up only every other drive cycle. any input very appreciated.

 

anyone?

 

:icon_fryingpan Did you find out your problem? I'm having same problem as you but my 05 Zr2 isn't going into 4th every time also. Any help appreciated thanks.
