Have your mechanic rig a light to the solenoid power and observe if it
stays on (not electrical) or goes out when the symptom occurs
(electrical) see Randall's #3

Very slim chance someone fitted a J-type along with a
later gearbox, but not<br>
likely. I guess anything is possible (I once saw a
Spitfire with a 426 Hemi<br>
under the hood), but you'd have to be slightly crazy to
put a LH or D type<br>
behind a TRactor motor.<br>
<br>
Things I would look at:<br>
1) Does the pressure hold when the problem is actually
happening? (Or did<br>
they only check it on the bench)<br>
<br>
2) How far does the ball in the operating valve actually
move? It's not<br>
unusual for components to wear until the "setting lever"
is no longer<br>
accurate.<br>
<br>
3) Is the solenoid still drawing current when the
problem happens?<br>
Obviously, if not, the problem is electrical (outside
the OD).<br>
<br>
FWIW, I am currently having a somewhat similar problem
with the A-type in my<br>
56 TR3. In my case, the problem is almost certainly the
3-4 isolator switch<br>
being intermittent. Bumping the shift lever slightly
forward (not enough to<br>
shift out of gear) or backward will usually get it to
make contact again.<br>
Sooner or later, I'll have to pull the cover and change
the switch. Maybe<br>
this time, I'll pay more attention to the number of
shims under it.<br>
<br>
I'm also curious how they established that the OD clutch
is not slipping.<br>
How much torque did they apply to try to make it slip?<br>
Was that while you were seeing the problem?<br>
