No way to be sure - it depends on how much abuse the trans has already seen. Do you know how old (miles) the ATF & filter are? Does it already have the upgraded brass bushing for the TV cable on the throttle lever? If not, take it to a slushbox pro for adjustment IMMEDIATELY.
And you really need to read the owner's manual.

How do you know if he has 1.5" or 2" springs, or what they're rated for? The tow package also includes F&R sway bars and quad front shocks, as well as brake controller wiring, trailer light relays & fuses, a steering damper...
