  Ther's nothing much in the solenoid but a whole lot of single-strand
wire.  The end of it is scraped clean and the stranded pigtail is
soldered to that.  I redid that joint when I installed a new pigtail. 
Nothing much to be heat sensitive.  The solenoid does draw a lot of
current, so the connections must be clean and tight throuout the wiring
harness, both on the tranny and in the car.

  Just a thought, but the 1 - 2 lockout switch on the upper left of the
tranny is adjustable for depth in the hole, has to be adjusted
correctly.   If you have the prob again you can bypass the switch by
running a wire direct from the solenoid to the car's wire harness.  I
put an extra wire in my OD wire harness when I made it up for just that
purpose. (Now watch someone tell me that's a no-no. (G) )  I don't run
it that way, gang.  Anyhoo, when the case heats up, thermal expansion
could marginalize the switch closure.
