On the side of the transmission is a black box with wire plugs check those first. unplug them clean them and reinsert and if the problem doesn't go away u will need a full shop diagnostic on it. they have multiple issues that it could be on that year range gm SUV

    sounds like you are going to need a complete shop diagnostic, if the shift selector module on the side is good you may have mechanical wear issues internally.

2008 Jeep Commander running fine then slows. Then its won't shift or move over 30 mph. Engine light comes on. Code says chip in transmission needs replaced. Need a good & honest Transmission Shop


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

Transmission -does fine until it warms up, then does not want to shift correctly, drive begins flashing.


d flash mans, tranny fault
so scan it. us the obd2 scan tool, any and scan it.
the A/T IS VERY complex, do the tests shown in the FSM
guessing dont work
but in general (experience)
wont shift correctly dont cut it. (200 parts, and 50 was to mess up)
????
flare, skips gears, wont up shift, wont down shift, or shifts wrong speed. what gears work, what dont. just a clue and help goes get better
The tranny TCM can go to limphome mode, this mode is very clear.
and covered in the FSM and
one common failure, that happens with high mileage and poor service (not doing a flush at 50k miles)
is stuck in 1st gear, hot. only.
the ATF fluid gets more thin hot and pump output drops
this is usually a vary bad sign.
the Stall test fails.
the pump pressure test fails, hot.
there is no vacuum lines to this electronically shifted trans.
the ended back 1990(about). with old 3speeds.

scan it, could be something slimple like
the PRNDL shift switch fibbing like crazy. (common)
this car has TCM, a transmission brain.
look for OBD2 DTC errors P07xx (trans)
this TCM (part of PCM) function relies on sensor for shifting
they are:
1: TPS
2: engine INPUT rpm
3: tranny output rpm
4: shift selector.
5: ECT (engine temps)
6: ECU part of the PCM calculates load at all times and sends that to the TCM , so that TCM can down shift on hills, or upshift faster on the flat or down hill.
this LOAD feature is what replaced the VACUUM of old days.

The D light , hopefully is just a bad input (cheap)
scan it. and see, its begging for you to do that.

The torque converter clutch issue, won't effect the
shifting issues

I would stop using it,unless your prepared to
completely rebuild it, in a few weeks.

It has to be diagnosed and resolved, now,quickly.

Having once owned a trans shop, I don't like the
fact your driving it at all,hung shifts for 7 miles

2001 Jetta won't shift into high gear/


In 2001 the "Check Engine" light might give information about what's going on with the transmission. You may want to have it checked by a shop before the transmission decides to die. It might be a simple fix.

Trans light comes on and then it won't shift into low


Sounds like either the range sensor is not properly adjusted or the kick down cable is not adjusted right.If the cable is not adjusted right early failure of the trans will happen.So if you can have them scan the van and see if the range selector which tells what gear its in is right and make sure the drown shift cable is adjusted right because thats what controls your shift pattern and controls and pressure to the trans.I hope that this helps you.Have a great day..
