I have a 2008 4L60e with ISS and 15 pin connector. Can this Trans. fit into a 2003 Silverado and operate correctly.

I would think as long as the Trans is a complete 2008 unit (Matching Pump, Input Drum, Valvebody, etc), it would just swap into the vehicle in place of the earlier 2003 model using a 13 pin connector, just the ISS and extra 2 pins would not be used for anything, as the vehicle side plug is provisioned with addt'l blank holes to accommodate the extra pins.

Can anyone confirm they have done this successfully with no problems.
