How to Remove the Tailshaft From a 727 Torqueflite


The first automatic transmission offered by the Chrysler Corporation for use in Plymouth, Dodge, DeSoto, Imperial and Chrysler vehicles was dubbed the Torqueflite and was introduced in the mid-1950s. An improved version -- called the A-727 Torqueflite -- was introduced in the early 1960s and used for many years afterwards. Some AMC and Jeep vehicles used Chrysler-built 727 Torqueflites as well. The tailshaft of the 727 Torqueflite adapts the rear of the transmission to the driveshaft, which powers the rear wheels.

Things You'll Need

  • Automotive ramps
  • 2 tire chocks
  • Chalk
  • Drain pan
  • Socket set
  • Ratchet wrench
  • Drive the vehicle onto a set of automotive ramps and apply the emergency brake. Chock the tires to prevent rolling.

  • Crawl under the vehicle and make a chalk mark on the driveshaft and on the transmission tailshaft, as this will ensure the driveshaft is installed into the correct position in relation to the tailshaft upon reassembly. Place a drain pan under the tailshaft.

  • Locate the four retaining nuts that secure the rear of the driveshaft to the rear differential. Loosen and remove the nuts with a socket and ratchet wrench. Pull the U-clamps from which the nuts were removed straight out. Lower the rear of the driveshaft from the differential. Slide the driveshaft towards the rear of the vehicle until it clears the transmission tailshaft. Note that a small amount of transmission fluid may leak of out the tailshaft. Place the driveshaft aside.

  • Locate the six retaining bolts that secure the tailshaft to the rear of the transmission. Loosen and remove the bolts with a socket and ratchet wrench.

  • Slide the tailshaft assembly straight out from the rear of the transmission and remove it. Note that the ball bearing behind the tailshaft may fall out once the tailshaft is removed from the transmission.

Tips & Warnings

  • The transmission tailshaft and the driveshaft may be installed in the reverse order of removal.
