TRANSMISSION ASSEMBLY
a. Measure dimensions “K” and “L”, and calculate dimension “J”.
i. Measure dimension “K” between
the converter housing fitting
surface of transmission case and the needle bearing mating sur-
face of under drive sun gear.
CAUTION:
Never change the straight edge installation position before
the completion of “L” measurement.
ii. Measure dimension “L” between the converter housing fitting surface of transmission case and the oil pump fitting surface of
transmission case.
iii. Measure dimension “K” and “L” in at least three places, and take the average.
iv. Calculate dimension “J”.
b. Measure dimensions “M
1” and “M2”, and calculate dimension
“M”.
1 : Transmission case
2 : Under drive sun gear
A : Straightedge
“J” : Distance between the oil pump fitting surface
of transmission case and the needle bearing
mating surface of under drive sun gear.

49. Adjustment of front brake clearance “C”.
 Measure clearance between front brake piston (1) and frontbrake retaining plate (2).
 Select proper thickness of front brake retaining plat so that
clearance is within specifications.
a. Measure dimensions “O” and “P”, and calculate dimension “N”.
i. Measure dimension “O” between the converter housing fitting surface of transmission case and the front brake retaining plate.
CAUTION:
Never change the straight edge installation position before
the completion of “P” measurement.
ii. Measure dimension “P” between the converter housing fitting
surface of transmission case and the oil pump fitting surface of
transmission case.
iii. Measure dimension “O” and “P” in at least three places, and take the average.
iv. Calculate dimension “N”.
