I've got an 09 Cobalt SS (E69/LNF) that I swapped out the F35 for an F23 manual trans. The vss reluctor on the F35 is 85 teeth vs the 29 on the F23; I've corrected the pulses per mi value and my speedo is reading correct, but the DIC appears to still calculate mileage/avg speed/mpg based on the old trans info.

Not a huge deal, more of an annoyance. Anyone else run into this problem? Am I missing something somewhere that will correct this? Is there a table not accessible in the E69 that would correct this?

Thanks,

Jim
