2005 ION-2 Sedan
Default Is it the TCM?

P2764 tcc open
P0973 shift solenoid A circuit low
P0976 shift solenoid B circuit low.

When shifting into drive, it stalls. It drives in reverse fine. But stalls when put into drive. I can reset the codes and drive in drive but engine light immediately comes back on and dies at a stoplight. I replaced solenoid A and B with no change. old solenoids worked after testing. don't know where to go now other than to replace TCM? Thank you in advance.

REWARD EXCELLENCE!

Default Re: Is it the TCM?

A brief reprint from the service manual;

When the TCM detects a continuous open or short to ground in the TCC PWM solenoid valve circuit, then DTC P2764 sets........... The TCM detects an open or short to ground on the TCC PWM solenoid valve circuit for 4.4 seconds.

Check for a blown 10 amp fuse, labeled TRANS 2 Fuse 13.
