This past week i got my car back with a new tranny and i noticed some differences. Before i could light up the tires inbetween first and second, now i am no where close. the car feels like they put different ratios on because 2nd gear does not take me as far as it use to. Before i could get to around 74 now i am getting to about 70ish. But in the lower end it feels like i have more pull so i am not sure if this new tranny hurt or helped

 

they probably made the car slower

 

recet the ecu and it will go back. i had the same thing.

 

they said that they put a new ecu in when i picked up the car, so i doubt resetting it would do any good

 

Give it a week for the ecu to create new maps for your car. After that if it feels sluggish talk to the dealership.
