P0715 Chevrolet -

Question

I just had my transmission "repaired" because I was experiencing hard shifting and other symptoms before I took my truck (07 Silverado) to the transmission shop the code P0715 came on but then it went off after a day or two anyways that was before taking the truck into the shop they did fixed the hard shifting but some of the symptoms came back one of them is when I shift from Drive to Reverse there is a "clunk" that I don't like but that is no really my concern my concern is that when I stop at a red light after a few seconds I feel and hear like if the truck (transmission) is down barely down shifting into first gear it feels like some one had heat me from the back of my truck I wonder if this could be that Input turbine speed sensor (P0715)???? According to the guy who "fixed"  the transmission this symptoms has nothing to do witb the transmission. Please Help! I don't know exactly why the truck does this at a red light not all the time I can't find an exact answer anywhere?

Answer 1

P0715 Transmission input / Turbine speed sensor circuit malfunction

This symptom has everything to do with the transmission. What happens when this code is set the transmission gear will change abruptly, As for the clunk noise, check the U-joints, of the drive shaft.
