Gary, from the MOPAR installation instructions for Stage 1:
"MOPAR STAGE 1 TRANSMISSION QUICK LEARN PROCEDURE
NOTE: With your new Mopar PT Turbo Stage 1 Upgrade
kit, you also receive new transmission calibrations
(automatic transmission only). After installing your
Mopar PT Turbo Stage 1 Upgrade Kit, you must perform
the following transmission quick learn procedure in
order to establish a baseline for shift quality. FAILURE
TO PERFORM THE FOLLOWING QUICK LEARN
PROCEDURE CAN RESULT IN POOR SHIFT QUALITY
AND POSSIBLE TRANSMISSION DAMAGE. YOUR
CAR CAN BE DRIVEN PRIOR TO PERFORMING THE
FOLLOWING PROCEDURE, HOWEVER, NO WIDE OPEN
THROTTLE (WOT) UPSHIFTS SHOULD BE DONE
UNTIL THIS PROCEDURE HAS BEEN PERFORMED.
Once you have performed the following procedure
and established a baseline, shift quality will continue
to improve as the transmission control module
continues to learn your particular driving style.
Allow the transmission fluid to reach normal operating
temperature. To do so, apply the parking brake and let
the engine idle in neutral until the engine cooling fan
has cycled (turned on and off) one complete time.
Perform 15 launches from 0 to 50 mph at 25% to 50%
throttle and brake lightly to a complete stop following
each launch. This will address the 1-2 and 2-3 upshifts,
as well as the 2-1 coastdowns as you brake to a stop.
Next, drive at 40 mph and tip into the throttle 50% to
100% until you achieve a 4-3 or 4-2 kickdown. Perform
this 10 times.
After these first 25 shifts, the quick learn procedure
should be complete. As mentioned above, shift quality
will continue to improve following the quick learn
procedure. Without these first 25 shifts, however,
your car could have poor shift quality."
Make sure you talk to your dealer about this very specifically. If you go to
http://www.mopar.com/pdf/7256_PTInstructionSheets.pdf you can print out the entire instructions. These instructions are for an '03 so the part about installing injectors does not apply to your '04 model. Nonetheless, the tranny quick learn is extremely important. My dealer told me that they would program the tranny and knew nothing about the quick learn procedure. One of the many reasons I didn't buy from them, or let them install it. Whether the dealer does it or you do it, just make absolutely certain it gets done.
