DIY Gearbox Replacement

Gearbox replacement is often a necessary process in order to assure that the car runs smoothly without compromising on the speed, possible oil leak and excess play in the steering wheel. A faulty gearbox requires either a replacement or repair and as replacement is a relatively more expensive option, it is usually recommended that it be adhered to when the issue is not a minor one and when repair is expected to get extensively problematic. Two kinds of gearbox or transmission are found in cars namely automatic or manual and either ways, its replacement is only a moderately challenging task. Using the tools and materials, as per the steps explained below, you can go about your project with little difficulty.

Tools and Materials Needed:

  • Floor jack
  • Wrench
  • Jack stand
  • Torque converter
  • Transmission jack

Step 1 - Lift the Car Up

Place the jack underneath the back as well as the front side of your vehicle. Use jack stands so that you may raise the car so you can crawl beneath the car and reach the gearbox easily.

Step 2 - Remove the Wiring

Once the car has been lifted up, let loose the fluid cables which are tied to the radiator. Also loosen the link cables that are connected to the gearbox. Using a wrench eradicate the 2 "U" bolts from the back end of your car. Glide the drive shaft away from the gearbox. Once these things have been removed, get the speedometer gear mechanism out and position the jack stand underneath the gearbox pan. Lift the gearbox and using a wrench. Get the torque converter bolts, cover of the lower bell housing, bell housing bolts, cross member bolts off (usually 4 in number) and rear transmission mounts off.

Step 3 - Replace the Gearbox

Once the wiring and cables mentioned in Step 2 have been removed, lower the transmission and move the jack towards the back side of your vehicle. See to it that all the components are unhooked. Proceed by taking out the worn out, old gearbox and place in the new replacement onto the jack, but slightly lift the gearbox while you slide it underneath the vehicle. Hold tightly onto the torque converters and turn them around until they click. Finish off the project by putting the cross member back and replacing the old vacuum lines found in the moderator (if applicable). Lastly, get your jack stand off the hook and lower your car to the ground.

Step 4 - Additional Tips

In order to avoid gearbox replacement and improve the working life of your gearbox, several tips and preventive recommendations can be used or applied.

  • Maintain the fluids in your car at a moderate temperature
  • Ensure that the pump and all other wiring works effectively
  • Replace the torn out or dysfunctional parts
  • Keep a regular check or balance on the devices running.

Usual problems with the gearbox could be easily avoided if maintenance of the filter are done consistently and responsibly.
