On some vehicles, the bands can be adjusted
externally with a torque wrench. On others, the transmission
fluid must be drained and the oil pan removed. Locate
the band-adjusting nut (Figure 40-20), then clean off all
dirt on and around the nut. Now, loosen the band-
adjusting bolt locknut and back it off approximately five
turns. Use a calibrated pound-inch torque wrench to
tighten the adjusting bolt to the specified torque. Then,
back off the adjusting screw the specified number of turns
and tighten the adjusting bolt locknut while holding the
adjusting stem stationary. Reinstall the oil pan with a new
gasket and refill the transmission with fluid. If the
transmission problem still exists, an oil pressure test or
Transmission teardown must be done.
