I've never had a car with rear gears before so this is new to me. When I take it on the parkway in D I get up to around 65mph and my rpms are up around 3500. I can't put it into OD because the OD band is almost completely shot. I'm afraid to go above 65 mph because i'm so damn close to the redline..... what's the deal? Is it normally like this when you have rear gears and an AOD?
