No, what is your shifting issue? How many miles? Fluid Change interval?

No, shifting in an automatic transmission is done by: A) How much throttle you are asking of it, mixed with B) Fluid pressure from the spinning gears. The movement of the transmission pushes fluid through ports and when the pressure reaches a threashold the force shifts gears. Tom above is on the right track.

You're battery is only used to start the car once the engine is running the altinator runs all of the electronics however aa bad alternator would not have any thing to do with the car shifting hard I would take it to a reputable transmission shop and find out what is wrong with ur cars tranny

Try adding some Lucas Transmission Fix Stop Slip. Works great on hard shifting. Do not over fill remove a quart if necessary.
