Maximum downhill braking can be attained at speeds below approximately 40 mph (64 km/h), with the selector lever in manual First position. Manual First oil pressure is the same as intermediate 827 kPa (120 psi) because intermediate oil is still present.

Lo oil from the manual valve is directed to the 1-2 throttle valve. Lo oil pressure and the 1-2 Throttle Valve (T.V.) spring force will close the 1-2 shift valve at speeds below approximately 40 mph (64 km/h). This allows lo oil to enter the lo 1st passage where it seats the lo 1st checkball (3) and passes through an orifice to the lo blow off valve, which exhausts lo 1st oil down to 241 kPa (35 psi). The lo 1st oil is then directed to seat the lo and reverse checkball (4) and to the lo and reverse clutch for a smooth apply.

SUMMARY
The forward clutch is applied. The lo and reverse clutch is applied. The transmission is in Manual First Gear.
