Final Assembly

Install brake band, band strut and band servo. Lubricate servo "O" rings before installing. Install and tighten retainer bolts. Loosen piston stem. Finger tighten brake band servo piston stem enough to prevent brake band and strut from falling out.
DO NOT adjust at this time. On L3N71B models, go to step 11 . On L4N71B, JM600 and E4N71B models, apply petroleum jelly to bearing race and thrust washer and mount them to drum support. Mount drum support gasket to drum support after coating with petroleum jelly. Apply clean ATF to "O" ring of drum support.
Align drum support with overdrive case to transmission case and install. Install overdrive case and temporarily tighten it using 2 converter housing securing bolts. Insert intermediate shaft. Make sure shaft is installed in correct direction.
Overdrive pack end play and overdrive total end play must be correct. To check overdrive pack end play, assemble direct clutch assembly, overdrive planetary gear set and connecting drum.
Install this assembly on overdrive pack. Install oil pump bearing, gasket and overdrive pack on oil pump. Measure dimensions "F" and "H". See Fig 1 . Attach thrust washer and needle bearing to the drum support and overdrive case. Measure dimensions "E" and "G". See Fig 1 .

Result of sum, "E" minus .004" (.1 mm), less dimension "F" is overdrive pack end play. Overdrive pack end play range is .020-.031" (.5-.8 mm). Overdrive pack end play can be changed with overdrive thrust washers of different thicknesses. These washers, which are same as high-reverse (front) clutch thrust washers, are available in thicknesses of .051-.106" (1.3-2.7 mm) in .008" (.2 mm) increments.
Result of sum, "G" minus .004" (.1 mm), less "H" is overdrive total end play. Total overdrive end play range is .0098-.0197" (.25-.50 mm). Adjust total overdrive end play with different thicknesses of overdrive bearing race. Races are available in thicknesses from .047-.087" (1.2-2.2 mm) in .008" (.2 mm) increments.

Adjust band by loosening lock nut and tightening stem to specifications. Then back-off specified number of turns. See BAND ADJUSTMENTS table. Make sure brake band strut is correctly installed.

BAND ADJUSTMENTS

Application	Tighten: INCH Lbs. (N.m)	Back-Off No. Turns
E4N71B & L4N71B
2nd Brake Band	108-132 (12-15)	2 Turns
OD Brake Band	108-132 (12-15)	3 Turns
L3N71B	108-132 (12-15)	2 Turns
JM600	60-84 (7-10)	2 Turns

Lubricate overdrive servo "O" rings with clean ATF. Install brake band, band strut and overdrive band servo. Apply clean ATF to seal ring of direct clutch. Install overdrive bearing and race, overdrive thrust washer and overdrive pack on drum support.
Make sure brake band strut is correctly installed. Apply clean ATF to "O" ring of oil pump. Install needle bearing, race and oil pump. Make sure oil pump housing and oil pump have been centered correctly. Adjust overdrive band. Tighten piston stem to 61-86 INCH lbs. (7-10 N.m). Back of 2 full turns and tighten piston stem lock nut.
On all models, use air gun with tapered rubber tip. Test overdrive band servo operation. Install accumulator parts. Install accumulator snap ring. Remove 2 converter housing bolts used to tighten overdrive case. Apply sealant to seating surfaces of converter housing at bolt locations. Install converter housing on overdrive case and tighten securing bolts. Install input shaft.
On L3N71B models, mount oil pump gasket on oil pump with petroleum jelly. Align pump to transmission case and install. Adjust band. See appropriate SERVICING article for band adjustment procedure. Make sure that brake band strut is correctly installed. Tighten piston stem to 108-132 INCH lbs. (12-15 N.m). Back off 2 full turns. Tighten lock nut.
On all models, use air gun with tapered rubber tip to perform final air check of all assembled components. See Fig 2 . Do this BEFORE proceeding with installation of valve body assembly. This will ensure that all bolts are tightened and that seals have not been damaged during assembly.

Check that parking pawl, pin, spring and washer are assembled correctly. Install rear extension. Install control valve body with correct length attaching bolts. See Fig 3 . Be sure manual valve is in alignment with selector pin. Tighten control valve body attaching bolts. Make sure manual lever can be moved to all positions after control valve body attaching bolts are tightened.

Before installing vacuum diaphragm valve, measure depth of hole in which it is inserted. Select proper length rod for depth of hole to ensure proper operation. See VACUUM DIAPHRAGM ROD SELECTION table. Install vacuum diaphragm. Make sure vacuum diaphragm rod does not interfere with side plate of control valve body.

VACUUM DIAPHRAGM ROD SELECTION

Hole Depth: In. (mm)	Rod Length: In. (mm)
Under 1.006 (25.55)	1.14 (29.0)
1.010-1.030 (25.65-26.05)	1.16 (29.5)
1.031-1.049 (26.15-26.55)	1.18 (30.0)
1.050-1.069 (26.65-27.05)	1.20 (30.5)
Over 1.070 (27.15)	1.22 (31.0)

Install downshift solenoid, overdrive cancel solenoid and overdrive indicator switch. Install neutral safety switch and check for proper operation. See appropriate SERVICING article for checking and adjustment procedures.
Before installing oil pan, check alignment and operation of control lever and parking pawl engagement. Clean mechanism with compressed air. Make final check to be sure all bolts are correctly installed in control valve body. Install oil pan with new gasket.
Install governor tube. Carefully inspect torque converter for damage. Check converter hub for grooves caused by hardened seals. Check bushing contact area. Lubricate oil pump lip seal and converter neck before installing converter. Install converter, making sure that converter is properly meshed with oil pump drive gear.
