It will most likely not, unless you have a GM Tech II or the like that can read trans codes.
While you are doing 70, are you maintaining speed, or trying to accelerate when the flucuation happens? It may not be your trans at all, could be tune-up related.

car never stalls it just has the problem at 70+ mph

took car to trans shops said torque converter slips at 70mph need solinoid

Dusty.. the maintenance on the car is up to par correct? Needing a tune up of plugs and wires or throttle body/maf cleaning can also exhibit the same symptoms.
