Automatic Transmission 45/545RFE

NOTE: Apply trans jell or petroleum jelly to all slide portions, rolling contacts surfaces, thrust surfaces etc. to prevent burnout during initial operation. Lubricate O-rings and O-ring seals with MOPAR® ATF+4. Soak all friction disks in MOPAR® ATF+4 for at least two hours before assembly of clutch packs.

NOTE: Clean and inspect all components. Replace any components which show evidence of excessive wear or scoring.

NOTE: If the transmission assembly is being reconditioned (clutch/seal replacement) or replaced, it is necessary to perform the Quick Learn Procedure using the scan tool. Refer to STANDARD PROCEDURE .

NOTE: Before final assembly of transmission centerline, the 2C/4C clutch components should be installed into position and measured as follows:

Install the 2C reaction plate (4) with the beveled edge down (rearward) into the transmission case. See Fig 6.
Install the 2C clutch pack (2, 3) into the transmission case. See Fig 6.

Install the 4C retainer/bulkhead (2) into the transmission case. Make sure that the oil feed holes are pointing toward the valve body area. See Fig 7.
Install the 4C retainer/bulkhead tapered snap-ring (1) into the transmission case. Make sure that the open ends of the snap-ring are located in the case opening toward the valve body area.
Using a feeler gauge through the opening in the rear of the transmission case, measure the 2C clutch pack clearance between the 2C reaction plate and the transmission case at four different points. The average of these measurements is the 2C clutch pack clearance. The correct clutch clearance is 0.455-1.335 mm (0.018-0.053 in.). The reaction plate is not selective. If the clutch pack clearance is not within specification, the reaction plate, all the friction discs, and steels must be replaced.
Remove the 4C retainer/bulkhead and all of the 2C clutch components from the transmission case.

Using Alignment Plate 8261 (1), Adapter 8266-17 from End-Play Tool Set 8266 (2) and Dial Indicator C-3339 (3), measure and record the output shaft end-play. The correct output shaft end-play is 0.22-0.55 mm (0.009-0.021 in.). Adjust as necessary. Install the chosen output shaft selective thrust plate and re-measure end-play to verify selection. See Fig 17.

1 - TOOL 8266

2 - TOOL C-3339

NOTE: When measuring the input shaft end-play, two "stops" will be felt. When the input shaft is pushed inward and the dial indicator zeroed, the first "stop" felt when the input shaft is pulled outward is the movement of the input shaft in the input clutch housing hub. This value should not be included in the end-play measured value and therefore must be recorded and subtracted from the dial indicator reading. If NO input shaft end play is noted, disassemble the input clutch assembly and check for the #2, #3, or #4 thrust bearing fallen out of position or cracked. Replace any cracked thrust bearing and reassemble using trans jell or petroleum jelly to retain the thrust bearings.

Using Adapter 8266-1 from End-Play Tool Set 8266 (1) and Dial Indicator C-3339 (2), measure and record the input shaft end-play. The correct end-play is 0.46-0.89 mm (0.018-0.035 in.). Adjust as necessary. Install the chosen thrust plate on the number 5 thrust bearing and re-measure end-play to verify selection. See Fig 20.
