Buy a NADP, Suncoast, ATS, or Goerend 68RFE Transmission.

Or get a tuner, run around on the 120HP tune and 20-80k miles later, buy the new transmission.

The 68RFE is designed for the 350/650 that comes stock in the truck. Bump up the power, drop the life expectancy of the transmission. If you're only going to keep the truck for 60k miles or so, just get an H&S tuner with the OVERDRIVE tuning and have fun.

Overdrive, MHP or B&G, or the Co-pilot by ATS are just new programs for your transmission.

In older transmissions you'd put a different valve body in or tweak things in the transmission to adjust your shift points, harshness, etc.

The 68RFE is fully electronic, so the program basically does the same thing as a "shift kit" did in the earlier transmissions.

The programming will only help to a certian extent as you still have the "hard parts" like your clutchs and other items that will not stand up to the extra HP & TQ for very long.

The performance transmissions offer upgraded "hard parts" such as different pumps, better and stronger clutch packs, billet components, better bearings, etc to make the transmission reliable with the higher HP & TQ numbers.
