there are bushing drivers that fit the bushings correctly. You can use a hammer to drive the bushing in if you have the correct bushing driver.
I use a chisel to remove the bushings and an arbor press to press bushings in.
Most tool trucks carry very little for internal transmission work. Prices on tranny tools are a bit high IMHO.
Dont worry how old you are... it is the mileage on your body that adds up.
