TRANSMISSION TRANSMISSION UNIT (DISASSEMBLY) Preparation SST 49 H075 4958 Body (Part of 49 U019 OAOA) For disassembly of transmission For disassembly of transmission For disassembly of transmission 49 U019 OAOA Hanger set, transmission 49 U019 003 Holder (Part of 49 U019 OAOA) For disassembly of transmission For disassembly of transmission Precaution General notes: 1. The oil pan could contain small chips, shavings, and other particles helpful in checking the condition of the transmission and diagnosing certain problems. To ensure that all foreign particles stay in the oil pan, make sure that the transmission is never tipped completely over while the oil pan is still installed. L/ 2. Disassemble transmission in a clean area (dust proof work space) to prevent entry of dust into the mech- anisms. 3. Inspect the individual transmission components in accordance with the QUICK DIAGNOSIS CHART during disassembly. 4. Use only plastic hammers when applying force to separate the light alloy case joints. 5. Never use rags during disassembly; they may leave particles that can clog fluid passages. 6. Several parts resemble one another; organize them so they do not get mixed up. 7. Disassemble the control valve assembly and thoroughly clean it when a clutch or brake band is burned; or when the ATF has degenerated. Cleaning notes: 1. Clean the transmission exterior thoroughly with steam or cleaning solvents, or both, before disassembly. Warning Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air. 2. Clean the removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages with compressed air, and check that there are no obstructions. Gartner Banana

TRANSMISSION K 29. Remove the bearing races and bearing. 30. Remove the intermediate shaft. I 45UOKX-116 31. Loosen the 2nd band servo locknut and tighten the pis- ton stem. I 1 45UOKX-117 32. Separate the drum support, accumulator and fourth gear case from the transmission case by tapping it lightly with a plastic hammer. Remove the gasket. u 45UOKX-118 Remove the bearing races and bearing from the drum support, accumulator and fourth gear case. Remove the bearing from the front clutch hole. Loosen the 2nd band servo piston stem and remove the 2nd band strut. Hold the brake band together with a piece of wire as shown in the figure. Remove the band strut. Gartner Banana

TRANSMISSION K DRUM SUPPORT (2) Measure distances C and D with a straight edge and vernier calipers. (3) Calculate the front clutch end play by using the for- mula below. Formula: T=C-04.1 mm {0.0039 In) T Front clutch end play. C: The distance between the drum support mounting surface (including the drum support gasket) of the transmission case and the bearing surface on the front clutch assembly. D: The distance between the sliding surface of the bearing and the drum support gasket contact sur- face. 0.1 :The compression amount of a new gasket. (4) Adjust the front clutch end play by selecting the prop- er bearing race. Front clutch end play: 0.5--0.8mm (0.020--0.031 in) Bearing race sizes rnm (in) 16. Set the 2nd brake band and strut in position. 17. Tighten the piston stem lightly. 18. Apply petroleum jelly to the bearings and bearing races, and install them as shown. Bearing outer diameter 0: 35.0mm (1.38 in) @: 70.0mm (2.76 in) Bearing race outer diameter 0: 76.0mm (2.99 in) 0: 33.0mm (1.30 in) Gartner Banana
