Title: Auto Transmission Solenoid Adjustment
Post by: KUMARB on November 20, 2009, 02:21:32

I just bought a new electromagnetic solenoid which mounts on the top of the automatic transmission and controls pressure regulation. The pressure regulation lever seems to move freely with a movement of 15 degrees. Is the free movement normal or do I I have a defective pressure regulator? 

The transmission is still mounted on the car.  How do  I fix the problem if I really have a defective pressure regulator?

Also, the ball attached to the lever of the solenoid broke off. Apparently, the ball is welded to the lever. Any guess why the ball broke off? This ball makes the ball and socket joint for the connecting rod to actuate the pressure regulation lever.

Thanks,

Hello,

These transmission linkage ends have a locking wire clip.  The clip locks the linkage onto the ball  and must be removed before the linkage can be removed.

The only way to tell if your modulator is adjusted correctly is to test it with a gauge.  Review the instructiions on "Sun Valley Auto Dismantlers" web site for a good break down on adjusting the modulator.

Joe is certainly right about the locking clips. I had originally thought that these sockets were the same as the throttle sockets and just popped off. They aren't. Maybe someone tried to pry the sockets off and ended up breaking it because of the locking clips.

I tried taking the clips off through the trans tunnel access hole and gave up. How do you remove these little monsters? Do you have to remove the trans to be able to get to them?

I also bought a new socket and a clip at the local MB dealership. They showed me how the clip fitted on the socket.

The clip sits in a groove on the socket neck.  With a finger nail or a flat screw driver, push the end of the clip (this end is on the right side of the socket, with socket facing down) up all the way, and slide out the clip.

My car has two access holes, on the top of the transmission tunnel and the other  on the right side. I found working on the solenoid easier when both access holes are open.

Good luck.

I just wanted to thank Joe Alexander and Wallace Wheeler for their helpful responses.  Thanks. Kumar
