Hello, and thank you for choosing Just Answer!

This is not a 'quick, easy' job..... it calls for 8.0 hours of labor to replace the TCC in this transmission.

Here are the different procedures that have to be done to change the TCC:

The OE service manual does not provide a specific service and repair procedure for the Torque Converter Clutch (TCC) solenoid, Refer to the following articles in the specified order;

about how much in price
Expert:  ase_master327 replied 8 years ago.
Well, the solenoid is cheap.. usually about 40-50 dollars.
The labor, on the other hand... Depending on where you take it, most shops charge between 60 - 110 an hour... The national average is close to 72 per hour, though. As I said the job calls for 8.0 hours of labor.
