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.
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
