Tranny Trouble? Rut-Roh...

[PGBCruiser]

Hey kids, funny thing happened on the way to the dentist.
Engine stalled a bit at low speed, just a hiccup. About 1/4 mile later I had a more definite stalling feeling, the speedometer whipped from 0 all the way to the right then back (very surprised it wasn't the tach).
I had to limp the car a few miles. As I approached 20 MPH the PT felt as though it should be shifting; but wouldn't (automatic trans). I kept it at 35 MPH maximum (in a 45 zone) and the tach was sitting at 3. I was afraid to take the car any faster.
Got to the dentist, had my appointment, then called AAA for a tow.
My usual garage told me they don't do tranny work so I should head to the dealer.
There my car sits as they said they were swamped and couldn't look at it 'til Saturday AM.
I'll keep you posted as the diagnosis and prices greet me in the morning.
Think good, inexpensive thoughts!

I would suggest that it might just be the output speed sensor or the wiring going to it. If the output speed sensor goes bad the TCM will shut off relay that powers the solenoid pack for shifting and puts the PT Cruiser in limp mode.

ptcruisersteve, that's pretty interesting in that the results of the initial stall was lack of shifting, "limping" the car to my destination. The initial stall made me think electrical in that the speedo went berserk and it seemed like more than just the engine stalling due to fuel line problems, etc.
My TCM was replaced 5/31/14, beyond the 12 month warranty; but the dealer service guys are pretty good so they may help me out.
If they recognize that it is the output sensor or wiring, then the TCM did exactly what it should do and may not need replacing.
Let's hope for the best!
Thanks for the info, always better to talk to these guys armed with a little knowledge!

And the winner is... ptcruisersteve! You nailed it.
From the invoice; Found Output Speed Sensor failing.
Remove and replace Output Speed Sensor with new, Quick Learn Trans, Perform PCM update, road test and clear codes.
So, my $27.50 replacement part cost a total of $447.25 out the door.
Svc Materials: $24.95
LAB/Mechanical: $367.50
State Sale Tax: $27.30

A lot for a 27.50 part; but I would not have a clue how to put it in and get it connected with the electrical/computer stuff. Paying for the knowledge of others.

Bottom line, it was a whole lot cheaper than a new tranny; and it you believe in Divine Providence, just today we received a check from our insurance provider for money they owed us... $415.
