The shifting is slowed by a little resitor next to the battery. You can unplug it to speed up shifting with the following side effects 1. semi-harsh shifts, 2. power light blinks on startup and returns a solenoid a error code, 3. the tranny will drop rpms and hunt for gears if you put the car in 3rd. My tranny failed in January, I have a 92 with 85k on it now. My first (and pretty much only) sign of failure was that the car wouldn't roll in D unless you pushed the gas, then one day it just wouldn't go in 1st gear. I don't think the synthetic oil would have any ill effects besides possible leakage.
