DIY Transmission Installation

  • webmaster
  • Apr 25, 2019

If you followed our steps in the previous post on how to successfully remove a transmission, you are ready to install the replacement transmission. Hopefully, you came to our Houston salvage yard and purchased one of our high-quality used transmissions to replace the old one. Purchasing a great used transmission from our Houston junkyard and installing it yourself can save you hundreds or even thousands of dollars. The following are general Do It Yourself guidelines to installing an automatic transmission:

  1. Using a jack, raise your automobile and secure it with jack stands.
  2. Install the torque converter (make sure to fill converter with one quart of transmission fluid before installation). Push and wiggle the converter until you feel three “clicks” each time the converter drops into place. This signals that the converter is engaged.
  3. Install transmission brackets.
  4. Clean off any dirt, grease, or burs found on the transmission bell housing and engine. *Note: transmissions purchased from Airline Auto Parts are already cleaned in advance.
  5. Lift up one side of the transmission and have someone else slide the jack under the transmission pan. Slide the jack under the vehicle. Position the jack so that when raised, the transmission bell housing will be slightly behind the engine.
  6. Raise the transmission and slide the jack forward until the bell housing touches the back of engine. Line up the dowels with the dowel holes and push the transmission forward. When the dowel pins are in the dowel holes, install the bell housing bolts.
  7. Line up the torque converter holes with holes in the flywheel and install the torque converter bolts.
  8. Install the starter. *Note: Get both starter bolts started before fully tightening the bolts. 
  9. Attach all electrical connectors and vacuum hoses. 
  10. Install the transmission oil filler dipstick tube and new filler tube O-ring.
  11. Install cooler lines, shifter linkage, exhaust, flywheel/flex-plate cover, cross member and then driveshaft.
  12. Remove the jack from underneath the vehicle. Jack up your automobile and remove the jack stands.  Lower your automobile to the ground.
