Re: Transmission Not Shifting Correctly on a 87 Colony Park
take a look at where the throttle cable connects to the throttle body... there is the throttle cable that opens the butterfly and another cablae that should be connected to the arm also that pulls out toward front of the car. many times the grommet goes bad since it is plastic and gets brittle with age. when it gets brittle, it crumbles and allows the tv cable to fall out where it needs to be connected to the throttle arm. when that happens, the transmission runs at low pressure and burns up the transmission. sounds like that is what happened. sad thing is it is mostly overlooked and that $3-$5 part not being changed causes a $800+ rebuild
