How to Rebuild a 700-R4 Transmission


Car maintenance comes in two flavors: simple and complex. The former generally includes changing your oil or a tire, and the latter extends into very involved procedures, such as rebuilding your 700-R4 transmission. Though the steps to this process are difficult, you can greatly simplify the process by purchasing a rebuild kit specific for your transmission. This allows you to have all of the tools you need specifically for your vehicle.

Things You'll Need

  • 700-R4 rebuild kit
  • Torque converter
  • Allen wrench
  • TV cable
  • Transmission fluid
  • Purchase a 700-R4 rebuild kit. Ensure that the kit is specific to your car's year due to the changes in manufacturing. For example, the 1982 version is built differently than one from 1992. Each kit comes with a manual that offers instructions specific to your year's vehicle.

  • Purchase the tools required by the kit to perform the task. While this might seem intuitive -- and you might have your own set of tools -- most transmissions require special tools just for that task, and the 700-R4 is no different. For example, you will need a torque converter with either a 27- or 30-spline input, depending on your car. Purchase only the tools your particular instructions require.

  • Locate your vehicle's transmission and unbolt its mounting bolts. Pull apart its bell-shaped housing using the small cylinders mounted in the wall, called pinion rods. When unbolted, the housing should come off with ease.

  • Locate the cogs on the lower rear end of the upper, lower and gear shift. Take the rear gears that came with your rebuild kit and place them on each of these slots. Tighten the tiny screws in the middle of each gear with your Allen wrench, securing them in their position.

  • Locate the two long rods that protrude from the transmission -- the spindle shafts -- and remove them. If there are any scratches, replace them with the ones from the kit. Alternately, use a grinder to hone them, but the safest bet is to use new ones altogether. Remove the rubber pushing between the spindle shafts and replace it with new rubber from the kit.

  • Replace additional parts not included with the kit. For example, while it is not inherently required to do so, replacing your TV cable can save you much trouble in the future. Despite its appearance, the old cable may not be properly adjusted to your rebuilt transmission, which will cause burn-up.

  • Replace the transmission fluid. With your new transmission, you will need the fluid to help it run.

  • Replace the bell-shaped housing on the transmission and put the mounting bolts back into position to secure the housing on the transmission.
