Topic: l949 Overdrive Solenoid Removal


JT Ford    -- 07-20-2013 @ 3:13 PM
  My OD will not re-engage after driving 20-30 miles after slowing down before 22 mph. After the car cool off it works fine until its been drove on the highway.

When taking the solenoid off a convertible, where should the pull cable be, In or Out? Do you turn the unit a quarter of turn like the sedans? Never had one out and its buried in the X fram. Thanks for any help

  As I recall, the dash cable position doesn't matter. Removing the solenoid in a convertible can be tricky, but turning a quarter should disengage the shaft. Check both the pull and hold points in the unit when you get it out. They should be dressed to remove any burned spots. Before you do that, check the governor contacts to be sure they are not sticking. That sound more like the cause of your problem.

  It should not be buried in the X frame. Someone has probably removed a bit of the X member and put a non-convertible installation. Here is an overdrive showing the assembly that lets you mount the solenoid underneath the transmission.

  Mine looks like the picture, but the frame is close to unit. Not much room for wrenches. I'll check the goveneor before removing the solenoid. But, like I said sometimes it work OK. So when I am testing things
it is operatoring normal. When its hot and doesn't work its too hot to do it under the car.............
Jim Taylor Thanks for any help. PS I'll let you know if aand when I get it fixed.

  If it looks like that you just take out the two bolts and the solenoid will turn and come out. It should be under the transmission so the frame is not in the way. You do not need to take out the governor to test it. Just hook up a temporary test light from the power out side of the relay. If it comes on when you go over 23 mph then the governor is working. Next step is kickdown switch and solenoid.

  As the photo shows, the convertibles used a special right angle adapter for the solenoid. Without it, removing the solenoid is not possible without pulling the transmission.

  Its got the convertible plate to off-set it. The one bolt look hard to get at, but I suppose its do-able.

I am going through the complete test of the system as soon as the temps lower some. The govenor look like it wouldn't be real easy to miss with either. Some
say the points may need cleaning up. If it has to come
off to do that, how bad will that be???

Also is there an oil seal for the plunger like the sedan for the solenoid

  Look closely at the picture and you will see two holes at the bottom of the plate. These should be nuts and bolts and will let you remove the solenoid. Then there is a hole at the top which is the remaining one holding the cover. When the cover is removed the other bolt holding the plate is accessed. The plate is then rotated and removed. You should not have to do this unless you want to replace the seal. It is the same one for all but there is an extra one for the adapter.
If you remove the solenoid and disassemble it take note of the angle of the flat in respect to the rest of the solenoid. There is a weep hole on the cover that should be positioned on the bottom to let out moisture. Also there are two coils on the solenoid. One is a pull in and the other is a holding. When it engages there are a set of points in there that switch one from the other. Also there are a set of point to ground the coil when the kick down is engaged. It may sound confusing but it is all pretty simple.
