Truck lunges/jerks at steady speed

Hey all, Noobie here and seeking help about an issue. Tried search but couldn't find anything. I've owned the truck for about 2 months. Its a 96 F350 ext cab, Auto with 4.10s. Truck has 67,000 miles on it and was well maintained by original owner with a trans fluid/filter change at 35,000 miles. Maint I've done so far has been new fuel filter w/ screen clean, BB mod, and 6637 mod and this happened prior to my maint. Problem happens occassionaly where I'll be driving at no particular speed, has happened at as low as 30mph and up to 55 mph. Constant throttle, truck lurches violently, feels like its slips out of gear them immediatly regains; almost like it wants to downshift but rethinks. Its very uncomfortable cause its neckbreaking when it does and happens so fast that I don;t have time to look at tach, CEL, OD light to diagnose area; so I have no idea where this is coming from. Any help is appreciated. Love this truck , and look foward to talking with you guys about mods to get it to run closer with my 01 Lightning.
