SOURCE: not shifting into passing gear
hi passing gear is actually your transmision drpping down to second gear.if you hit the gas hard.if you hit the gas lightly it will only drop out of overdrive and go into third and not go into passing gear.
SOURCE: I have a GMC Yukon XL that shifts hard 1st to 2nd gear.
sound like shift valves sticking in valve body.
SOURCE: transmission shift problems
this could be a shift solenoid, a trans connector problem or a control module problem, the 1st thing to do is have the system tested or trouble codes and let me know what they find.
