Will a faulty alternator effect the transmission

My car has 112000 miles.
My car has an automatic transmission.

If you have a faulty alternator and the vehicle battery gets low on voltage then the computer may not shift the transmission gears correctly and cause other drive symptoms like stalling or surges and rough shifts. Engine and transmission may even go into failure mode and cause various drive symptoms.
