1998 Saturn sc2. got stuck in snow tried rocking car to get it out didn’t work had to be pushed out. after that check engine light on and when i get to about 40 mph wont go in to overdrive. ran diagnostics came back with code PO734 gear 4 incorrect ratio. what does that mean? do i need a new tranny or are there other things i can do first to try and fix without having to replace tranny?

  1. You can try replacing the shift solenoids inside the transmission as long as the trans fluid is nice and clean looking. If the trans fluid is dark or burnt looking, it time for a new tranny.

  2. can a transmission for a 1998 saturn sc1 be put onto a sc2
