I've had the Ltd. for three years with no problems. I've now had the SRT-6 three months, and it has cutting-out twice while stopped at a light. I don't believe I restarted the engine the first time, but just as the light changed (a minute and half wait) it began to run normally.

The second time was at a longer light stop for the Metro Railcar to pass by. Eventually I turned off the engine and restarted, once again when 'all clear' it ran perfectly. A bit weird in that the two cutting out's were only a quarter mile apart on the same street.

What I've garnered from reading the previous comments is:

Put dielectric grease on the TB relay clip (a hint where it is located?)

Really need help here: install a new APPS and (??) its wires to the PCM (whatever/wherever that might be).

Replace the electrical plate IN (??) the transmission with a new speed sensor.

[Could someone tell me how they 'know' it is either an APPS problem or a trans speed sensor?]

Are there any tests for these - or is it just easier to replace then bother testing?

After all is completed (correctly), it shouldn't cut out any more?
