Does anyone have some knowledge on shifting problems with these transmissions? I have a 99 GTP that I just
bought used. I feel that it revs way higher than it should (~5-6000 rpm) at highway speeds. So I went to a parts store and got them to do a free scan on the PCM computer. A DTC
code of P0756 came up. It refers to the the "2-3 Shift Solenoid Valve Performance". The info the parts place gave me on P0756 states that if the PCM commands 1st gear, but the gear ratio indicates 4th gear for 2 seconds, or, if the PCM commands 2 gear, but the gear ratio indicates 3rd gear for 1 second then DTC P0756 sets. This has the following action:
-The PCM illuminates the malfunction indicator lamp
-The PCM commands 3rd gear
-The PCM commands max line pressure
-The PCM inhibits TCC
-The PCM freezes shift adapts
-The PCM stores DTC P0756 in it's history
Would I be correct in telling the tranny guys to basically not fool around and just go straight to the 2-3 shift solenoid? Suggestions?
