Does anyone know what the top speed of each gear is for the 7AT?

 

The following is the factory spec, though the actual top speed will vary based on real time conditions:

 

Thank you!

 

what is stall torque? Would changing this help improve acceleration?

 

Stall torque, or stall speed, is the maximum amount of torque that can be generated while output remains zero.

In a nutshell, it is the maximum RPM's a engine can turn while the transmission is in gear without moving (brakes fully applied).

A higher stall speed will affect acceleration, but there are way too many variables in that equation to come up with a concrete answer. In reality, the cons can highly outweigh the benefits. Unless you are going for a fully built race car, this is not a real viable option for a daily driver.
