How can I tell if I have a 3 speed automatic transmission or a 4 speed automatic transmission?
Does the vehicle number have it somewhere?
My transmission was replaced with rebuilt transmission could they have used a 3 speed or 4 speed?

It has three speeds but 4th gear is achieved by the lockup torque convertor. So there are 4 speeds like 4 is OD
