Below is a sketch documenting how I checked the over-drive relay after I lost the use of over-drive last winter. It follows a technique I’d seen posted on the Brick Board, probably by Dave Barton. It took a while to troubleshoot but I eventually sucked it up and got the $40 Over-drive Solenoid Bypass kit from IPD and it’s worked great since then.
UPDATE: Added photo of the bypass kit install at bottom of this post.
In the ongoing saga of my transmission shifter, I discovered the retaining ring I installed isn’t the right fix. It snapped off at some point, and I was left back where I started. Actually, it was worse, because I had to shut the car off while it was sticking 1/2 way into the street with no ability to get out of gear. While I biked to the hardware store my wife had to deal with a local cop, who demanded the car be moved off the street. I got back and quickly put on a new clip, only to have that one pop off 5 minutes later.
Obviously the retaining clip doesn’t work so I posted an inquiry on the Brick Board. Art Benstein posted some great pics and it was explained to me that I either needed to weld the end of the rod adjuster to a washer, or flare the end around a tight fitting washer. I chose the later and here’s the result.
I’m hoping that this fix, plus new bushings for the shift levers and a new transmission mount, will solve the shifting problems. Because I don’t need to be stuck in reverse in a parking lot with no way to park.
Last night after grocery shopping with the family I discovered a problem with the brick. It started up fine, but when I went to put it in reverse the shift lever went slack. I tried putting it back in Park, but it was stuck in reverse and the shift lever could just bounce back and forth through the range of gears without any resistance. I pulled the parking brake, shut it off and explored under the car.
A rod hung from underneath the shift lever and after a little exploring I saw that it should have been attached to another lever on the transmission. But there was nothing to hold it in place. I was parked over a sewer grate, so if there had been something that fell of it was gone. Luckily I had just thrown a roll of duct tape into the trunk, so I was able to fasten the levers and drive home.
This morning I removed the duct tape, pulled the mechanism and walked to the local hardware store for a retaining ring and washer. The guy in the nuts and bolts section was clueless when I asked for help. He told me they didn’t have retaining rings, but after a short search on my own I found a drawer with plenty.
Reassembly was easy and now it shifts properly. But the whole shift assembly is loose and sloppy, so someday I may have to go in there and swap out some of the bushings. Right now I’m just glad we were able to get home, and the repair only cost $.75 in parts.
