Jim Yergin Posted April 14, 2008 Report Posted April 14, 2008 I was checking the operation of the electrical switches on my R10 O/D transmission. The lockout switch was not working when I locked out the O/D. The switch itself tested OK but I discovered that I am missing the lockout switch plunger that operates the switch when the lockout arm is moved. As far as I know I never had that plunger. Does anyone have a picture and/or dimensions of the plunger? I found a reference to it in the manual but no illustration. Thanks. Jim Yergin Quote
Dodgeb4ya Posted April 14, 2008 Report Posted April 14, 2008 Jim, Here is a picture of the lockout plunger. Length is .598" Diameter is .3735" Bob Quote
Jim Yergin Posted April 15, 2008 Author Report Posted April 15, 2008 Bob, Thank you very much. I guess I will see what I can fabricate. Jim Yergin Quote
Jim Yergin Posted April 16, 2008 Author Report Posted April 16, 2008 Thanks to Bob's picture and dimensions I was able to fabricate a plunger using 3/8" steel round rod and my bench grinder. The lockout switch now operates correctly. I am very glad I decided to remove the transmission and overhaul it otherwise I would not have discovered that the plunger was missing. Without that plunger the transmission would have been in permanent lockout and I would not have known why. In my search for a replacement plunger I contacted Neil Riddle. He did not have one right now but he did tell me that it is very common to have them missing if the transmission has ever been opened up. The Borg-Warner manual does not even mention the plunger. The Chrysler Corporation Overdrive maintenance pamphlet does mention it in the reassembly portion but not the disassembly section. If anyone has acquired an O/D without knowing its history, I recommend that at a minimum you remove the lockout switch and verify that the plunger is in there. Thanks again Bob. Jim Quote
Joe Flanagan Posted April 16, 2008 Report Posted April 16, 2008 Thanks Jim. All your trials and tribulations will be instructive for me when I do the same thing. I wasn't going to open up my OD but I think now that it might be foolish not to. Also, anything that will prolong my project is OK by me. Quote
