test a transmission out of the car?

I dont plan on spending money on the 904 because I despise automatics and the only valid use for one is if you have missing or disfunctional limbs.They take so much fun and joy out of driving that every car is boring to drive unless it has stupid amounts of power.There is fundamentally no difference in driving my 93 v8 dakota with an autotragic and my 2005 dodge grand caravan.Both are appliances, although one sounds alot better and accelerates faster.Neither of them compare to my 84 Nissan 300ZX turbo 5 speed or my 310 hp/686 lb-ft at the rear wheels 94 Dodge ram 2500 CTD with a 5 speed.With the 904 I'm just interested in seeing if it works to decide if I should keep it or sell it.
