I have a four speed automatic. The check engine light was on p0715 was the code. I had the g68 speed sensor changed, water and cooling fan sensors changed. No codes still in limp mode? I get and overheat warning light intermittently. Also sometimes the check engine light flashes. I was able to read a code once stating P0715 circuit A.
Can anyone please tell me what may be going on here? Or where I should look?
Thank you

The first thing you should look at since you already changed the sensor is the wiring. Look for faulty wiring that has either chafed, corroded or broken wires or connector. Has there been a leak of the transmission fluid that could have caused damage to the wiring or connector? Check the wiring between T2 and T68 and the connectors themselves.

Hope that helps.
