I would have to say that I agree with the overhaul and certainly with the trans-go kit. You can also install the alto red eagle 3-4 clutch pack and a kevlar 2-4 band.
You may want to look for a later model case. Pre-87 case's are weak and 84 may still have the smaller input shaft. 87+ with the aux valve body is the best case, install the above mentioned parts and also certainly upgrade the forward sprag to a 30 element as well as the pump vane and rotor assy to at least a 10 vane if not more (4L65E 13 vane works great), hardened reaction sun shell (aka "the beast") and hardened input housing. The list goes on and on as far as upgrades you can do but these are the bare minimums I would go with and I've built my fair share of 700's while at the dealer level.

As for your original question, the hard pedal certainly usually indicates a bad throttle valve. That can be replaced easy enough during the rebuild process without having to replace the entire valve body. These valve bodies were still cast so they don't wear as easy as the newer alluminum valve bodies we are dealing with today.......

Oh, and I would stay away from Jasper........
