The 3rd gear issue should be pretty easy since 4th gear works and it is the=
same switch for both of them. Sounds like the isolation switch just needs=
to be threaded in slightly more so that the switch closes when in 3rd. Sh=
ouldn't take much.
The 2nd gear could be the same issue IF you have an isolation switch instal=
led.. if the switch is missing it means the top cover has to come off and d=
isassembled to be able to drill and tap for a switch. May not be worth it.
Possibly the wiring could be wrong for the 2nd gear setup though I can envi=
sion what that would take. Probably worth taking the car up on the lift to=
see if you can figure it out from below but most times the gearbox cover w=
ill come off for this kind of work.
Cheers
Randy

Subject: [TR] A-type OD questions
I have had my TR4A transmission converted to an A-type OD by noted special=
ist, and the removal/installation service was done by a reputable shop.
I just got it back and the OD seems to work perfectly in 4th gear.
In Third, It will work for a short time, then goes out of OD. It appears t=
hat it is related to the isolator switch. If I gently push the shifter for=
ward, it stays in OD just fine. If I pull it back slightly (still in 3rd),=
it does out of OD, and when I push it slightly forward again, OD re-engage=
s.
In second gear, it does not ever engage OD. I did not see the transmission =
after the conversion, so I do not know IF there is a 2nd gear isolator swit=
ch. But, I think there OUGHT to be..
I picked up the car at the end of last week, and I am sure the shops will m=
ake good on a perfectly functioning OD. But I want to know if this is a si=
mple adjustment issue. Maybe I can do it myself. I can get the car on a l=
ift and do the work from below if it were feasible.
I would rather not pull the interior to access the top, but maybe it is nec=
essary.
Any advice/experience with this sort of issue?
