[95 King GT]

i just bought a New High performance AODE Called the AODE INTERCEPTER, (off of transmissioncenter.net) and i had it Installed at a transmission shop, It drives and shift great, But when I give full throtle around 30mph It just revs up to 5grand then shifts It neutrals out, SO the tranny shop changed the Lever position Sensor. TPS Sensor, still nothing , so I sent the tranny back and got another one just in case it was a bad tranny but we got the same thing , I can't figure it out, Someone told me It might be the Vehicle Speed Sensor, Please Help
