2 - STRAIGHTEDGE
  1. Check torque converter hub and hub drive flats for sharp edges burrs, scratches, or nicks. Polish the hub and flats with 800/1000 grit paper and crocus cloth if necessary. Verify that the converter hub o-ring is properly installed and is free of any debris. The hub must be smooth to avoid damaging pump seal at installation.
  2. If a replacement transmission is being installed, transfer any components necessary, such as the manual shift lever and shift cable bracket, from the original transmission onto the replacement transmission.
  3. Lubricate oil pump seal lip with transmission fluid.
  4. Align converter and oil pump.
  5. Carefully insert converter in oil pump. Then rotate converter back and forth until fully seated in pump gears.
  6. Check converter seating with steel scale and straightedge. Surface of converter lugs should be in front of the bell housing face about 25 mm, (1 in.).
