We have an old '87 Maxima, automatic transmission. We start the car.
It runs reasonably well. Upon putting it into gear, either
drive or reverse, the car lurches briefly, then the engine immediately
dies.
We suspected the converter lock-up solenoid was not working. Ran some
"click" tests and were mostly unable to hear any clicks
(except once, weakly). This lock up solenoid has been giving symptoms
of going bad for some time.... lurching at stop lights, etc.
Does anyone have any experience, recommendations with the lock-up
solenoid? Just some moral support would be helpful, as we intend
to dig into the tranny and see what's going on with it. Anyway to
bypass it, like tinkering with the valve body or something? The
cheeseball solenoid itself is over $100 dollars!

Also the transmission controller could be suspect. But I don't know how to
diagnose it. Try getting a shop manual.

We did the click tests directly from the leads to the solenoid in the
transmission. Furthermore, we tried applying power directly to the
leads leading directly into the solenoid in the transmission
(bypassing any computer junk). This should have engaged the solenoid,
thus disengaging the converter clutch. We still had the same problem
upon trying to shift into gear.

Turns out the lock-up solenoid was good. The valve body itself was
bad.
