installed a differential and now its in limp mode
so 3 years ago me and my dad put a new differential in a chrysler 300 c
hemi 5.7L 2006 and now its stuck in limp mode and the differential is a
different ratio and we tried to tune it but it just keeps failing im using a
versus snap on it spits out 3 codes one is gear ratio and 1st and 2nd gear
but if we are driving its only 2nd and gear ratio codes that pop up.
but i don't really know anything about it.we tried getting the dealer ship to
fix it but they cant we tried a transmissions shop too so i don't know if we
should just get a whole new differential that match's the tmc's ratios and
that would just fix it but if anyone can tell me how to tune it,it would save my
dad a ton of money.
