Looks like the Engine is eithe rout of a Truck or Van,so probly 350,and the Trans would most likely be a 700R4 if out of a truck or Van. unless you are pulling a laod woth the truck or actually somehow getting it to hookup to the pavement,i dont think u should be worried about what trans it is...lol youll have enough power to burn the tires and too little of weight to hurt the trans.
