So I finally got my mustang back up and running after my new heart transplant (motor swap). The problem I have now is that the guy I bought the car from swears the car is not geared, but the speedo reads 90mph when im only doing 75mph (gps confirmed). I also scored some 3.73's in a deal but im affraid it already has them... so how can I confirm this without pulling apart my whole rear end if I dont have to? Also the AODE has been acting a little funny. When I take off and it tries to shift to 2nd it falls on its face for a little bit (feels like forever) before it shifts real hard braking the wheels loose again in second. I figured the tranny was done but didnt really care cause im swapping to manual here soon anyways, but i was just looking through other threads and just read that if its geared and the comp hasn't been chipped or adjusted/tuned the shift points could be off by up to 20%. So is this the possible problem with my tranny?
