Hey there, i've changed the transmission roles for the automatic gearbox, however when the car needs to gear up, the next gear takes a while to come in, making the car to increase the RPM Reading over the net and talking to another mechanics told me that i need to ride the car for a while in order to make the gearbox used to the car again
My questions: 1) is that true? 2) If not... Do i need to change my gearbox? thanks
My car has 170000 miles.
My car has an automatic transmission.
