How difficult is it to replace the overdrive solenoid on a 940, what's involved? I am a solid mechanic, but I don't want to get over my head with the tranny. I change my own fluid but that's it for trannys and me, at least up to this point... Any input?

 

Try doing a search for "Overdrive Solenoid" and see what pops up.

 

I did some digging and decided to go with the bypass kit from ipd. I'll post an update when I've completed the work.

 

Simple; located on the left side high on the trans;

Held on with 2 12MM bolts. Angle is tight; and may need a
bent 12MM wrench.

Test the relay; by removing the cover; and manually clicking
the magnetic lever.

Before you pull it; test it first with a 12V+ direct lead.

Before you re-assemble; blow out the air passages.

If your solenoid unit is dead; remove the plunger; and it
will be full time overdrive.

Good luck. And use jack stands for safety
