4L60E TCC Valve P1870 Fix (1996-2006 w/ OBD2 Computer) Fitzall

Product Description

A TCC (torque converter clutch) valve for GM 4L60E transmissions with an OBDII computer, addressing the P1870 code for 1996 to 2006 model years.

It can be converted to the A74741Q design by extending the cut groove and removing the end of the stem, which is recommended if you have a 1999/2000 model and are not sure which valve you need. It will not work on 2005-up vehicles with a CANBUS computer.
