my 01 42le tranny self-destructed, so i swapped it out with a 04 42le it all looked the same. same wiring harness,everything bolts up.finished install,started up fine but noticed that the gear indicator lights on dash all light up when in park and neutral when in reverse just the R lights up, when in drive just the D lights up also just the D lights up when in 3 or L. as far as drivability issues reverse works, neutral works, drive works, but won't go into 'low' or '3'. also when driving in 'D' and causing a downshift by accelerating, engine rpm.s won't go past about 3800 rpm.but just driving normal seems to work fine. anyone have a thought on what might be the cause? thanks Bob
