Hi there,

Here is the code description:

Description 

- The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehicle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.
- Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
- When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

It is possible you have an issue with the wiring, the TCM or the cvt itself. There are a lot of tests that need to be run prior to calling it a bad transmission. This needs the dealer or a transmission shop.
