I'm having some work on my transmission done and the guy doing it says that some codes are coming up on the PCM. What types of codes would come up on the PCM due to a transmission? It's got a 2400rpm stall, shift kit, beefed up clutches, and springs. The TC is a lock-up.

Also, he's trying to reset the codes, and for some reason the error codes are still present after the PCM has been re-flashed. He's got someone looking into it now.

Any ideas of what can cause this?

 

A4 related codes on OBD-I:

58 - Transmission fluid temp circuit, voltage low, high temperature

59 - Transmission fluid temp circuit, voltage high, low temperature

72 - VSS loss

73 - Pressure control solenoid circuit, current error

74 - TCS circuit low

75 - Transmission system voltage low

79 - Transmission fluid overtemp

80 - Transmission component slipping

81 - Transmission 2-3 shift solenoid circuit

82 - Transmission 1-2 shift solenoid circuit

84 - (A4) Transmission 3-2 control solenoid circuit

85 - Transmission TCC stuck "on"

90 -Transmission TCC solenoid circuit

 

Thanks for the reply!
