21. Install reverse gear shift rail into transmission case by aligning ball stud with slot in case and aligning reverse gear shift rail with reverse shift fork. Once ball stud enters case, rotate reverse gear shift rail clockwise and push in reverse gear shift rail until ball aligns with reverse gearshift lever. Rotate reverse gear shift rail counterclockwise until ball stud fully engages reverse gearshift lever.





22. Install fifth speed cluster gear, synchronizer and gear shifter fork as an assembly.





23. Install synchronizer blocking ring, brake ring retainer and fifth gear synchronizer snap ring

NOTE: Alignment tab on the brake ring must engage the alignment slot in the extension housing when installing the extension housing to prevent component damage.

24. Apply Pipe Sealant with Teflon D8AZ-19554-A or equivalent meeting Ford specifications WSK-M2G350-A2 and ESR-M18P7-A to the shift rail rear pin threads and install the shift rail rear pin.

NOTE: Before installing the shift rail rear pin, make sure the reverse gear shift rail ball stud is fully engaged with the reverse gearshift lever.





Tighten shift rail rear pin to 34-47 Nm (25-34 ft. lbs.) using a T55 Torx(r) driver. Apply Pipe Sealant with Teflon D8AZ-19554-A or equivalent meeting Ford specifications WSK-M2G350-A2 and ESR-M18P7-A to the backup lamp switch and install using a 22 mm socket. Tighten to 27-47 Nm (20-34 ft. lbs.).





25. Using needle nose pliers, install reverse idler gear retaining ring on shift rail rear pin.





26. Install speedometer drive gear.

NOTE: The tab on the speedometer drive gear retaining clip engages a hole in the output and fifth gear drive shaft.

27. Apply 3.2 mm (1/8 inch) bead of Silicone Rubber D6AZ-19562-AA or equivalent meeting Ford specifications ESB-M4G92-A and ESE-M4G195-A to case cover assembly.

CAUTION: Do not apply silicone sealer to top of transmission case surface under any circumstances, as sealant could fall into transmission and affect operation.





28. Position case cover to filler plug side of transmission and lower into position until gear shifter forks engage synchronizers. Continue lowering case cover and move into position to engage reverse gearshift lever. Install case cover retaining bolts. Tighten case cover retaining bolts to 8-15 Nm (71-132 inch lbs.).

NOTE: Make sure all synchronizers are in the NEUTRAL position and that the gear shifter forks in the case cover are in the NEUTRAL Position.





29. Apply a 3.2 mm (1/8-inch) bead of Silicone Rubber D6AZ-19562-AA or equivalent meeting Ford specifications ESB-M4G92-A and ESE-M4G195-A on the extension housing mating surface. Apply silicone rubber to the oil pick-up funnel and install funnel to extension housing.

30. Coat shifter interlock spring with petroleum jelly and install in gearshift offset lever. Lubricate detent plate and install detent ball in neutral position on plate. Position gearshift offset lever in extension housing with shifter interlock spring over detent ball.





31. Slide gearshift offset lever and extension housing into position as an assembly.

NOTE: Make sure lubrication funnel engages into fifth-gear synchronizer.





32. Press downward on gearshift offset lever to compress shifter interlock spring and push gearshift offset lever and extension housing into position.





33. Install extension housing retaining bolts. Tighten to 47-61 Nm (35-44 ft. lbs.).





34. Using a suitable pin punch, align the hole in main shift control shaft with hole in gearshift offset lever and install roll pin. Install gearshift shaft bushing in gearshift offset lever.





35. Check output shaft geartrain end play as follows:

NOTE: Output shaft geartrain end play must be checked and adjusted at this point.

^ Rotate transmission to the vertical position with extension housing facing up.
^ Mount Dial Indicator with Bracketry TOOL-4201-C or equivalent on the extension housing with the indicator stylus contacting the output and fifth gear drive shaft.
^ Rotate the input shaft and output and fifth gear drive shafts. Zero the dial indicator.





^ Using a wood block, push upward on the input shaft and note the dial indicator reading.





36. Rotate transmission to the horizontal position and remove the main drive gear bearing retainer. Remove bearing race from main drive gear bearing retainer and install the necessary shim(s).

Shim Thickness In Thousandths Of An Inch:

NOTE: A shim must be installed that is the thickness of the dial indicator reading. This will provide zero end play.

CAUTION:
^ Thickest shim must be installed closest to the front bearing cup for necessary cup support.
^ Although zero end play is the ideal end play, up to 0.050 mm (0.002 inch) is an acceptable tolerance. Do not overload the bearings with too thick a shim as transmission damage may occur.





37. Apply a 3.2 mm (1/8 inch) bead of Silicone Rubber D6AZ-19562-AA or equivalent meeting Ford specifications ESB-M4G92-A and ESE-M4G195-A to main drive gear bearing retainer.
