I have had my TR4A transmission converted to an A-type OD by  noted specialist, 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 that it is related to the isolator switch.  If I gently push the shifter forward, 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-engages.
 
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 switch.  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 make good on a perfectly functioning OD.  But I want to know if this is a simple adjustment issue.  Maybe I can do it myself.  I can get the car on a lift 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 necessary.
 
Any advice/experience with this sort of issue?

I do believe (haven=E2=80=99t 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.

I am hoping that the top was drilled properly.  But it makes me wonder when it can be made to go in and out of OD by pressing the shifter slightly forward and backward all while in 3rd gear. 

It almost strikes be as if the drill hole is a little too far forward…..????   Could that actually be the case?   I have no idea because I don’t know the precise shape and positioning of whatever it is on the selector that triggers the switch.

Randy, thanks for the info. It would be wonderful if I could get my fingers o=
nto the 3rd/4th switch from below to see if it has unscrewed itself a tiny a=
mount somehow.

Same for verifying the PRESENCE of the 2nd gear switch. =20

Thought to DO anything about it seems as if it will require pulling the inte=
rior. =20

I am assuming the shop that did the removal and install will be willing to m=
ake this right.   And the shop that did the transmission could deal with the=
  control top, I suppose maybe without the need to pull the whole transmissi=
on?? =20

Install a thinner washer. Generally fixes that symptom. DP
