Description
B Position
The flow of fluid through the torque converter circuit is the same as in position.
The line pressure (1) becomes the line pressure (3) and flows to the 1-2 shift valve. The line pressure (3) becomes line
pressure (3') at the 1-2 shift valve and flows to the servo valve. The servo valve is moved to the right side (Reverse range
position) and uncovers the port to allow line pressure (3") to the manual valve as in position. The line pressure (3")
from the servo valve is intercepted by the manual valve.
However, hydraulic pressure is not supplied to the clutches, and power is not transmitted.
NOTE: When used, "left" or "right" indicates direction on the hydraulic circuit.

Inspection (cont'd)
6. Measure the 2nd gear axial clearance while pushing
the 4th/2nd clutch toward the 1st clutch.
STANDARD: 0.07 - 0.15 mm (0.003 - 0.006 in)
NOTE: Take measurements in at least three places,
and use the average as the actual clearance.
7. If the clearance is out of tolerance, remove the 2nd
gear thrust washer and measure its thickness.
8. Select and install a new 2nd gear thrust washer,
then recheck.
2ND GEAR THRUST WASHER, 37.5 x 56 mm
9. After replacing the 2nd gear thrust washer, make
sure that the clearance is within tolerance.ProCarManuals.com
