TR6 1972 TR6 with "A"OD, issue with shift cover

[bailee2]

Seems I have broken/jammed something on the shift rods.
When coming our of reverse the shifter jams up.
All gears run through OK.

In-addition, sometimes the transmission will jump out of reverse.
I don't drive this car hard at all.
Restored ground up in 2007. Transmission came with the car new and rebuilt once.

If I replace the cover is it the same as a standard 4 speed? Which I believe it's not.
Before I remove anything I would like to have all the parts there to reduce down time.

Can a standard 4 speed cover be modified if this is the case?
I appreciate any advice.
Thanks Arlie

Arlie, it's possible that you may need no parts. A selector fork could be loose. The jumping out of reverse is probably only a spring adjustment. This: https://www.vtr.org/maintain/TransRebuild/TRTrans02.pdf should help show whats going on in there. I would also look thru this: https://www.buckeyetriumphs.org/technical/Gearbox/GearboxCover/GearboxCover.htm.
I'm pretty sure you have room to take the cover off once the dash support is removed but will let someone with a TR6 confirm.

Trans shift covers are the same. You will have to drill and tap the std cover to install the o/d switches. Other than that you can swap out. All this can be done without pulling the trans out of the car. I may have a spare trans cover that is for an overdrive. I do have several std covers. PM me if you want one.

Not as simple as it might seem, though. The hole location is important, and not necessarily centered on the boss in the casting. Plus the thread is a weird metric size, not usually found in sets.

Thanks all.
I will remove the dash center console and transmision cover later today to inspect.
I appreciate your help.
