View Full Version : AOD Shifter Lever Issue

I am using a rebuilt Ford AOD and, as part of installing the shifter assembly, am also replacing the stock shift lever (the part that sticks into the transmission) with a Lokar unit. I hit a snag and could really use some insights. I bought the tranny from a non-local supplier, and I would prefer to solve this myself or locally.


The Lokar instructions and the geometry of the linkage requires that the shift lever be vertical when the transmission is in Park. As delivered, my AOD lever was in the 2:30 or 3:00 position. To swap the lever or reset the existing one, I first need to pull the 1/8” roll pin that holds the lever assembly in place. As delivered, the pin was mounted near flush (typically it sticks out about an eighth to a quarter inch). The Lokar instructions suggest that I use diagonal cutters to grip the pin and, using the transmission case as leverage, wiggle it out. Looks good on paper…

My best guesses is that either the pin is working far better than intended, or the rebuilder used Lok-Tite, or I am inept. In either event, that bugger is NOT moving. I've (a) snapped a couple of carbide drills trying to drill it out, (b) lubricated it, let it sit overnight, and the trying drilling a hole in the case next to (touching) the roll pin hole, and (c) I've used so much force wiggling/leveraging the cutters that the pin is now cut flush with the case. I cannot get a screw or hook in there to pull from behind; the inside of the case is now mangled (but not the machined area where the gasket sits); the pin is now mangled; and I still have the OEM shift lever out of place.

Has anybody here had a similar issue? What have you done to address it?

Thanks,

Brian

Is there anything stopping you from tapping it out with a drift the opposite direction?

Yes. The entire transmission. :) It is a blind hole.

Maybe use a dremel tool to machine a "screwdriver slot" in the end of the pin and try to get it moving with a screwdriver?

I agree, your options are pretty limited. Another option is to grinf down the trans case around the pin so you can grab the pin.

Thanks. Your and Dale's ideas are similar to some that I pulled from the "practical machinist" forum and a couple of mustang-related sites, so I will be trying those later this week.

If necessary, Plan B will be to fab a lever extender similar to the attached pic, which will shift the clocking from 2:30 up to 12. A bit labor-intensive, but it beats pulling the tranny and going to AAMCO.
