PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX
controller only to the PCM. Those vehicle TCMs only communicate to the DRBIII® using
CCD communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting
those modules to the DRBIII® vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because
of this you will need to use the Yellow SuperCard2, CH8361, to set pinion factor or when
using a "new" (superseded) TCM from parts as only the SuperCard2 properly sets the
pinion factor on these updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.
