How many speeds on a 1993 Nissan Maxima SE automatic transmission?
should be a 4 speed automatic
Your car most likely has an automatic transmission. If you're noticing the rpms going up and down it is because your automatic transmission is using its torque converter. it uses the torque converter to get the transmission up to speed with the engine and then it locks but when the torque gets to be too much for the engine it unlocks and speeds back up again.
