Re: Alternator output for transmission.
You need 13.8V to charge the batt. Under a major load it might drop down around 12V, which is OK if it's only for a short time, as you're not charging the batt.
It's hard to say if low voltage will cause a problem, you didn't state what year or tranny you have.

Re: Alternator output for transmission.
YES, low volt WILL cause retarded symptoms through out the whole truck.
OUTPUT volt from alt should be nothing less then 14v while truck is running WITH accessories on, if it's less then this, it's dying.
