Sorry to hear about the issues you're having KnightRiderSS. Hopefully those codes don't pop up again for you and you are able to enjoy your vehicle from here on out. Glad to see your dealer was willing to work with you with your modifications as well.

Thanks for chiming in Jeff! I really hope it was just a fluke!

[KnightRiderSS]

Jeez...happened again...

Must not be a fluke....back to the dealer I go...same symptoms...this time I won't clear the codes and will let them look at it

The tranny reset after I shut the car off but seemed to want to "jump" through the gears instead of sliding into them...

Well hope they get it fixed.

DTC P0700: Transmission Control Module (TCM) Requested MIL Illumination

<A href="http://gsi.xw.gm.com/si/cellHandler.do?cellId=144619&refDoc=2415226&from=s m#ss3-2220046">Circuit/System Description

This diagnostic trouble code (DTC) indicates that an emission related transmission DTC has set in the transmission control module (TCM). The engine control module (ECM) turns ON the malfunction indicator lamp (MIL) when the TCM sends a message over the serial data circuit requesting MIL illumination. The DTC information for the ECM will only display DTC P0700, and the ECM Freeze Frame/Failure Records data will display the engine operating conditions that were present when the transmission DTC was set. The TCM Freeze Frame/Failure records data is available from the DTC that was set in the TCM.

• The ignition is ON or the engine is operating.
• DTC P0700 runs continuously.

The ECM receives a serial data message from the TCM requesting the ECM to turn ON the MIL.
