P0740 code...TCC circut solenoid.
Ok so for the past two weeks my Check engine light comes and goes...
it will stay on for a day or so, then go off for a day or so.
the code is the p0740(tcc solenoid circut)
Now I found the solenoid for 68 bucks at a local trans mission supply.(after chrystler wanted 274 bucks!!!)
But I am wondering if anyone has an idea of what pins to check off the Trans harness to verify it is indeed bad before I go purchase the part drop the pan just to find out its not bad... dont want to replace the part only to figure out I got a bad trans harness or TCU? not sure where the TCU even is or how to tell if its bad. some advice is welcomed! thanks.
