[TR] A-type OD questions

[Allen Hess]

I do believe (haven’t checked the manual) that the isolator switches on top of the gearbox have paper washer shims to adjust the on/off of the switch. There should be a 2nd gear switch and if you have backup lights, one on reverse. So I think you do have to pull the trans cover.

If I pull it back slightly (still in 3rd), it does out of OD, and when I push it slightly forward again, OD re-engages.
