Well, it's certainly looking like the motor needs to come out again.
Everything was triple-checked this evening to no avail. The old TC was
reused -- drained and refilled.

I recommend that you get access to a factory service manual. If you do not
have one, yhou can get on line access at techinfo.toyota.com. There is a
procedure for testing the one way clutch in the torque converter and for
checking how the TC engages the transmission body.

Question -- Do either of you know whether or not it's possible to
damage the oil pump by incorrectly installing the torque converter?
The prevailing question now is whether to replace the transmission or
to attempt it _again_ with the unit that isn't working.

Yes, I suppose it is theoretically possible to damage the oil pump by
incorrectly installing the TC, but I would imagine that it would make a huge
grinding noise if the notches in the TC didn't engage the notches in the
transmission.

Is there a way to test the pump with the transmission out of the car?
Perhaps by filling it up and turning the torque converter by hand?
Will that build up enough pressure to tell us anything?

Thanks again!

The factory service manual has specs on line pressures at the test ports on
the transmission with the transmission installed. I recommend actually
measuring line pressure before removing the transmisison again.

My guess is that the TC did not engage the front pump when it was installed.

my 1989 v6 Camry . Did you also replace the TC or just did a drain and
re-fill on the old unit? When sliding the TC back on you must make
absolutely sure it is engaged with the front pump. It is very possible
to
slide it on without engaging the pump. The TC has 2 slots where it needs
to
engage. With the TC out of the transmission, you can see through the
transmission front seal where the 2 slots must engage.

The motor went out, presumably rod bearings based on the horrible noise
it was making -- so we acquired another longblock and proceeded to swap
it out. Unbolted the transmission, torque converter from the old
motor, refilled the torque converter with fluid, attached the torque
converter to the transmission, making sure the splines connected on
both the gear shaft and oil pump shaft, bolted it all back together,
and now it won't engage any gear.

Any ideas?

The transmission was working fine before. The 'new' motor sounds
perfect. Fluid level shows full, the linkage is reconnected and
appears to work properly. No fluid pressure exists. I can pull the
top hose on the tranny oil cooler and nothing comes out.

I know next to nothing about auto trannies. They're magic to me. Did
we neglect some important step? Is the oil pump trashed? Does it need
to be primed in some fashion? Any suggestions would be greatly
appreciate as I have no idea what to do short of getting a junkyard
tranny and bolting it up instead.

Thanks!
