Installing a S-10 T-5 five-speed transmission in a flathead 6-powered Dodge or Plymouth Truck with a truck style bellhousing

  1. Press fit the enclosed bronze pilot bushing into the rear of the crankshaft.  This bushing fits the nose of the T-5 to the opening in the crank. (Figure 1). Make sure to remove the old pilot bushing before trying to install the bushing in the kit.
  2. Press fit the enclosed, larger bushing into the standard Mopar throw-out bearing. (Figure 1 & 2).



    You may need to heat the enclosed thin ring over the front bearing retainer of the T-5. This insures and exact alignment of the T-5 transmission into the original bellhousing.

    DO NOT SKIP THIS STEP! 5th gear failure will result!
    (Figure 3).




  3. Drill and Tap four new holes into your original TRUCK bellhousing to match the four mounting holes on the T-5.  Use a transfer punch to locate these holes.
  4. Enlarge the opening in the center brace of the TRUCK frame to accommodate the larger T-5 tail shaft.
  5. Attached a compatible T-5 universal joint yoke in the mounted transmission and measure u-joint to u-joint centers to have a new driveshaft made (or you can use your existing driveshaft with a new front yoke welded to it to match the T-5 u-joint).
  6. Final "clean-up" include a new wooden or metal floorboard to accommodate the shifter location and create a new longer shifter handle then add a shifter boot to cover the hole.
