4L60E/4L65E/4L70E TCC on/off conversion valve 2005-UP
This valve help prevent or repairs most PO1870 codes by converting 1996-2006 TCC to on/off, removing modulation during lock up.
NOTE: The 77754A is easily converted into the 77754 by continuing the cut (groove) and removing the end of the stem. If you have a 1999/2000 and you’re not sure which valve you need… order 77754A
