Front Unit End Play Check CAUTION If end play procedures are not closely followed, incorrect shim thickness will be selected, resulting in severe damage to internal transmission components. 1. Install dial indicator on transmission case (2) to read vertical movement on turbine shaft (5). 2. Press down turbine shaft (5) and pry up on output carrier (7) to eliminate slack between end of turbine shaft (5) and stator shaft (6). 3. Pull up turbine shaft (5) to eliminate slack between snapring on turbine shaft (5) and overdrive carrier. 4. Zero dial indicator. 5. Pull turbine shaft (5) forward, and read dial indicator. NOTE * Selective washer controlling end play is located between pump cover and forward clutch housing, refer to para. 17-22. If more or less washer thickness is required to bring end play within specifications, select proper washer from table 17-6. * An oil-soaked washer may tend to discolor. * It will be necessary to measure washer for its actual thickness. Table 17-6. Front Selective Washer Thickness THICKNESS COLOR 0.057-0.061 in. (1.45-1.55 min) Blue 0.073-0.077 in. (1.85-1.96 mm) Red 0.089-0.093 in. (2.26-2.36 mm) Brown 0.105-0.109 in. (2.67-2.77 mm) Green 0.121-0.125 in. (3.07-3.18 mm) Plain 6. Resulting travel or end play should be 0.004-0.022 in. (0.102-0.559 mm).
