I am replacing the overdrive solenoid in my son's '83 240 turbo. It is an automatic. Can anyone tell me what is involved. How do you access the wiring in the shifter. How does the shifter come apart or is it necessary to take it apart? Where do the "O" rings go. I suppose this is all obvious when one tears into the project but I'm trying to avoid any surprises. Thanks Mark

make sure it is you selniod. I replace it once and it wasn't my problem. it turned out to be the relay. and the relay is a hell of a lot easier and cheaper.

good luck

hi there. the o.d. solenoid is located on the tranny. i believe you might need a 12mm crowfoot wrench/socket. once removed it will be clear where the orings go. did you check your overdrive relay? did you check the o.d. switch? did you check the wiring down near the o.d. solenoid. this is the problems i had in the past that will cause your situation. the o.d. switch comes out fairly easy but the wires going to the switch dont have much excess to play with. maybe go to junkyard and practice on a couple to gain experience. good luck

try searching for it. theres got to be at least 20048039287409735098 million posts on everybodies friend the )($*&#(&)#(*%ing overdrive solenoid.

just make sure you clean around that thing like a maniac.

and it's a hell of alot easier to change the thing if the tranny is dropped down a few inches.

man i hated that thing... i scored a brand new solenoid at the pick and pull for a dollar which can't be beat.
