2. Lubricate converter drive hub and oil pump seal lip with transmission fluid.
3. Align converter and oil pump.
4. Carefully insert converter in oil pump. Then rotate converter back and forth until fully seated in pump gears.

Fig. 139 Checking Converter Seating - Typical:

5. Check converter seating with steel scale and straightedge (Fig. 139). Surface of converter lugs should be � inch to rear of straightedge when converter is fully seated.
6. Temporarily secure converter with C-clamp.
7. Lightly grease crankshaft flange hole.
8. Position transmission on jack and secure it with safety chains.
9. Check condition of converter driveplate. Replace the plate if cracked, distorted or damaged. Also be sure transmission dowel pins are seated in engine block and protrude far enough to hold transmission in alignment.
10. Raise transmission and align converter with drive plate and converter housing with engine block.
11. Move transmission forward. Then raise, lower or tilt transmission to align converter housing with engine block dowels.
12. Carefully work transmission forward and over engine block dowels until converter hub is seated in crankshaft.
13. Install and tighten bolts that attach transmission converter housing to engine block.

CAUTION: Be sure the converter housing is fully seated on the engine block dowels before tightening any bolts.

14. Install torque converter attaching bolts. Tighten bolts to 88 Nm (65 ft. lbs.).
