The transmission fluid, filter still new

Answer 1

HI there

The code is for the torque converter solenoid. What is happening is the torque converter is not locking up in the highest gear. If the fluid is in good condition then it's either a problem with the TCM, the solenoid or the wiring to the solenoid. There could also be a mechanical issue with the transmission.
