Governor replacement and T.V. cable adjustment or replacement are repairs that can, if the problem is identified early, be performed at a fraction of the cost of a transmission rebuild or replacement. In the event of an internal clutch failure, technicians consider the transmission to have failed. The most cost-efficient means of preventing a problem is switching to a high-quality synthetic automatic transmission fluid and changing the fluid and filter at the recommended intervals. For large and heavy vehicles, an aftermarket transmission cooler is recommended by many mechanics.

To improve the automatic overdrive, mechanics upgrade and harden the input shafts and upgrade the valve bodies.When upgrading input shafts, mechanics typically use parts made from billet or chromium-molybdenum alloy. To control overdrive, they may use an electric solenoid. For some people, the automatic overdrive is a problem because its converter is locked mechanically, although others prefer it because the overdrive is not computer-controlled.

In standard form, the Ford automatic overdrive can accommodate about 250 feet-pounds of torque and 300 horsepower. Mechanics can modify the transmission to accommodate between 700 and 800 horsepower.
