Replaced rear transmission mount (hydraulic) I unhooked battery for several hours. After I finished installing mount , I drove car and transmission slipped really bad going into all gears , if you leave off gas it goes into gear with a jerk ?

 

Did you reattach the vacuum hose to the mount ?

 

Yes I did, I figured it out . It was the shift control valve under the battery box. I lifted the tranny to high and damaged the solenoid . I replaced it off an old transmission I had and it ran perfect . Thank you
