Code P0751 ??
OK, I am getting a code that is troubling me....
10-PCM P0751 H C
I've done a bunch of poling around here looking for info, and every person that has this code is as a result of putting in a High Stall Torque Converter. However, I am running a STOCK torque converter. So, in my case, what could this mean?

The service manual gives a pretty thorough explanation of what sets this code.
The code indicates there could be a problem on a shift solenoid valve or an associated hydraulic circuit in the transmission. One of the possible causes are damaged seals on the valve.
If you have trouble reading the diagnostic you really should go to a dealer or qualified transmission shop to get the trouble analyzed and repaired.

Had that code after a tranny install. Check the connector at the trans for a bad pin or socket. Do the doors lock cycle, if you shift? It will sometimes lurch on start up. I finally had the issue resolved via a PCM tune... highly recommended to synch up your drive train.. my locks still cycle but the code doesnt set anymore. Drove me nuts for awhile but it was in the PCM not the connectors or the solenoids

Never had any issues with the door locks. Sounds like a different animal. I know that the code can be disabled during a PCM tune which makes sense if you are getting nuisance codes after a TC upgrade. I would guess that your tuner just hid the problem by disabling the code.
