Transmission suddenly stopped shifting. It works in 1-2nd &R. Was working fine then would not go forward and would stall the engine. It was like the wheels locked up going forward only, reverse was fine. I backed the car onto a hill and drifted down in nuetral. When I put it in gear the wheels started turning but won't shift past 2nd gear, and the check engine light came on immediately. Could this be the ground strap, wiring. What causes this?

there is no chip in the trans. sorry.
check fuses.
then this time scan it and write down the DTCs errors numbers.
and post those, we cant guess these critical facts.

find any ASE shop, and get it checked.
they dont need to cheat you,there work load is near infinite.
no reasons at all.


no over 30mph, did the transmission up shift.?
is it stuck in 1gear. surely you can count the gears shifted?
if not , get a real mech.
if the transmission file the FSM stall test. then this it.
1: tranny RPM goes too high RPM (engine RPM) this is transmission slip.
2: RPM in drive, 1,2, or R, is too low below 1500rpm. STALLED.
this is weak engine. not trans.
see?

google stall test transmission. and read.
or read the FSM
or read same on alldata.com

Don't know-- but your done

Pull it out & go thru it

You provided no mileage or how long it
was used & slipping or not shifting correctly
or if the fluid was EVER Changed

Transmission is done,burnt up,you know that
Has to come out & be rebuilt

Sorry to tell you this. You have an AXOD/AX4N Transmission and it is going bad on you. Soon, it is going to strand you on the road.

This Transmission is a Money Maker for the Mechanics and Transmission shops around the world.

Some people will put Lucas into their transmissions to extend the life of the Transmission but there are people who do that and cause it do DIE!!!! and I mean Immediately.

I am sorry to give you the bad news but at least it is Honest...

Replace the Torque Converter Solenoid in
the transaxle

What you have is like coming to a stop with
a manual shift & not pushing in the clutch & it stalls
the motor

The converter clutch is staying locked & your
trans is connected to the motor

Sounds like a IAC motor issue (idle air control motor) it controls your idle when you stop or put the ac on it adjusts the idle so you wont stall. it could be dirty or maybe worn out due to age .Very common that they do wear out .

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

Check the output sensor on the transmission,
With out a speedometer the transmission does not know how fast you are going or when it should shift

There is a pin in the transmission that has sheared off or a band has come loose. Bottom line you need to have the transmission serviced and repaired.

YES SOUNDS LIKE IT IS THE SOLENOID NOT SHIFTING INTO REVERSE OR TRANSMISSION CONTROL MODULE NOT SENDING SIGNAL TO VALVE BODY SOLENOID
