[B]Diagnostic code 1870... 99 v6 firebird[/B] Diagnostic code 1870... 99 v6 firebird my sis's 99 v6 firebird's trany is shot. Dia code 1870 comes up, trans component slipping with no apparent problem, is usally caused by a worn tcc regulator valve bore. this bore can be repaired with a kit which will restore the valve body's hydraulic integrity. Could this be the problem? I haven't driven the car to hear it, she went to a dealer and they gave her that code. Anybody please help thank you. |

That code is usually associated with a malfunctioning Torque Converter clutch. Most of the time, this is caused by the TCC Regulator valve like you mentioned, but can sometimes be the converter itself. A TransGo Reprogramming kit will fix the valvebody issue since it has a redesigned Regulator Valve, plus you get enhanced shift performance to boot. |
thanks for the info |
