Years ago this problem was very frequent. Charging systems are far more advanced now.If the voltage regulator is bad, I can see that the higher than expected
voltage increased the current, causing the fusing to blow out. However,
if the voltage regulator is good (if the voltage regulator is on the
alternator, one would hope it is good), then the voltage should be ok.
So the possible problems include:
1) Bad voltage regulator, leading to too high a voltage, causing the
fuses to blow out.
2) The mechanic used the wrong fuses.
3) There is a short circuit in the circuits controlled by the fuses.
It should be easy to test for [1] with a voltmeter and [2] by checking the
fuse ratings against the ones in the owner's manual. If it is [3], some needs to go and figure out where the short(s) is.

sounds like one of your main fuses has blown
Are there any fuses that would cause the transmission not to reverse?
No. That is mechanical, not electric.

How fuses are rated?
Fuses are rated by amperage (current) and voltage. The larger the current need, the larger the rating of the fuse, to handle the current. The voltage rating of a fuse defines the maximum value of circuit voltage in which the fuse can be safely used. A fuse should not be used in a circuit with a voltage exceeding the voltage rating of the fuse.

have you checked the fuses?
What would cause fuses to blow in a 1994 cavalier?
possible grounded or bare wire
Fuses increase or decrease the voltage of a current electrcity?
Fuses have absolutely no effect whatsoever on the voltage applied to a circuit. Fuses are simply overcurrent protection devices, intended to disconnect the circuit in the event of a sustained overload current or a short-circuit fault current.
If you boosted your 1980 suzuki gs1100e with your car and now you keep blowing headlight fuses would you have fried your voltage regulator?
most likely.
