2. The second function of the assembly involves the T.V. exhaust valve lifter rod, spring and the T.V. exhaust ball. The function of this system is
to prevent the transmission from operating at low (idle position) pressures, if the T.V. cable should become broken or disconnected. If the
cable is not connected or broken, the T.V. lifter rod will not move from its normal spring loaded position which holds the T.V. exhaust check
ball off its seat. The T.V. lifter rod will drop down to allow the T.V. exhaust ball to seat only if the cable is broken, disconnected or extremely
out of adjustment. With the transmission pan removed, it should be possible to pull down on the T.V. exhaust valve lifter rod and the springs
return the rod to its normal position. If the throttle lever and bracket assembly or lifter rod binds or sticks so that the T.V. lifter rod cannot lift
the exhaust ball off its seat, high line pressures and delayed upshifts will result. The normal shape of the T.V. lifter rod is shown in Figure
7A-6. The right angle leg must not be bent to any other angle or it will not function properly.
