i work at a chry jeep eagle dealer as a tech, usually the trannys come with a torque conv, those trannys are pretty straight forward, there are no tricks or special tools, just dont forget to support the engine and FLUSH THE TRANS COOLER (this is probably the most important) sometimes the trans cooler will be plugged, and will cause the tranny to overheat and if so warranty void. if you dont have a trans cooler flush kit use some brake cleaner and blow it through the lines with compressed air. hope this is of some help.
