95 lebaron GTC acting a bit strange

1995 Lebaron GTC 3.0L with 95,000 miles, second (!!!) rebuilt transmission
( yep, A-604 with the revised solenoid pack and using ATF +4 fluid), less
than 1000 miles on this transmission and I've replaced the output speed
sensor, cleaned and tightened all underhood connectors I could reach and
re-trained the transmission computer (late version with heat sink).

Speedometer occasionally quits and trans goes into limp mode. Sometimes this
happens at start up and a restart often fixes it, sometimes it happens while
driving (under 45 mph, I ain't going out on the highway with it!!) and a
rolling restart fixes it, then a quick second start gets the trans out of
limp mode.

When the trans shifts correctly, it works just like it's supposed to, smooth
shifts, 4 speeds, lockup all work as they should. It worked well for about
200 miles after installation before this all began

Tried a new ignition switch (Standard brand), but I had only limp mode with
the new switch and it was much harder to operate. That really puzzles me . .
.. it was installed correctly, nothing jammed up.

Idle rpm is often high or erratic when these things happen, but I have a AIS
motor on order and it should be in any day. Will R&R throttle body, clean it
and install the new AIS.

Any help would be appreciated. Any links to parts sources also, would be
helpful.

TIA

I forgot to mention that I can't take it to a dealership as the closest one
is in Grand Junction CO and I live in Moab UT, 112 miles one way. There are
no local mechanics with a dependable reputation, and a Ford dealer, and a GM
dealer, and I have no means to haul it over there. I am on fixed income.

I wish to publicly thank Ed M, who made a good try to assist me with my
car's problems. His answer did not help since my transmission uses the
output sensor to give speed readings, but he tried.

Thank you, Ed, but it looks the car will be down for a long time so I will
be looking for another vehicle.

Is it setting any codes?
Key from of to on 3 times.
I would recheck the speed sensor and wiring real close.

 

Now that I've decided to park it until I can save up some money to buy a
second vehicle, someone responds . . .oh,wow.

The book I got for my transmission (A604) from ATSG didn't give the right
code list. It contains the list for the minivans, not Lebaron cars. My
Haynes manual doesn't give the right code list because I checked and
repaired / replaced the items on the key codes pointed to and the darn thing
still acted up, that's how I ended up with a $24 output speed sensor, $85
dollar AIS, a $1600 rebuilt transmission (retrained according to the ATSG
manual), a $45 aftermarket ignition switch that doesn't work and can't be
returned bcause it's an electrical part.

You apparently didn't read the OP very close or you would know I cleaned,
tightened, etc. all the underhood connectors I could reach, that I replaced
the transmission, output speed sensor, the ignition switch and today, the
AIS. So far, the car is working ok, worked correctly on three test drives,
but it's done that before also, then back to limp mode after a couple days
and a few miles.

Btw, yes, I know how to get the key codes. I get "12" and "55" at present.
Battery was disconnected while cleaning the throttle body and installing the
AIS.

Now, I'm going to go start looking for another, older and more dependable
car so I don't have to bum rides everywhere.

As for this thread, it's done. No more replies needed from anyone else.
