Re: 98 Vs 94 4L60E

[Len Sabatine <sabatine@epix.net>]

      Might want to check if 94 4L60E has PWM Pump , 98 has it , OBD2 PCM
      will be looking for it. If 94 is sans , Install later PWM Pump and 
change the
      internal harness and connector. Trans control harness from 94 PCM 
will be
      missing the required extra wire[s]. Ya just need to compare what you 
have
      against the 98. Most 95 and later 4L60Es are PWM, Most 94 and earlier
      are not. The 98 trans should have  a bolt on bell housing , your 94 
may not.
      Compare all functions from the 98 to your 94 , avoids problems 
later.You'll
      need longer Selector- Detent  shaft to utilize the external PRNDL / 
BackUp
      Light switch module and the needed Metri Pack connectors.If you get 
the 98
      Trans, get torque converter with it.   FYI.
