VALVE BODY, GOEREND, HIGH PRESSURE WITH SOLENOIDS
Our custom valve bodies, built in house, fill the torque converter in all gears, including park. This ensures that the front bushing of the transmission will get oil while the engine is idling.
The lube circuit of the valve body is modified such that there is always line pressure feeding the lube circuit. With the factory valve body, when the transmission gets hot, you may lose oil to the lube circuit while decelerating downhill if the engine is at low rpm or idle. With our upgraded valve body this will not happen.
Our valve body has increased pressures starting at 60-75 psi at idle and up to 150-175 psi at wide open throttle. A factory valve body has pressures of 50-60 psi at idle and 85-95 psi at wide open throttle. Even though our pressures are much higher than stock our transmission still retains a smooth shift. We do not like a firm bang shift.
This valve body is capable of lockup in 2nd through 4th or optionally, all forward gears. If 1st through 4th lockup is desired a toggle switch can be added at no extra charge. A manual lockup switch is used with an exhaust brake or to keep transmission temperatures down while towing uphill.
When the valve body is built to lock up in 2nd through 4th, the engine will not be killed if you forget to turn off the toggle switch when you come to a stop.
For race applications you can turn the lockup switch on at the starting line and the converter will lock when it shifts to 2nd. For sled pulling, you may want it to lock in 1st also.
Please note that we do not recommend letting the transmission shift from one gear to the next while the converter is locked, unless equipped with "billet" shafts.
The new valve body comes complete with solenoids. The governor pressure solenoid and governor pressure sensor are new factory Dodge parts.
When using a new valve body a stronger 1-2 shift lever is also recommended. The higher pressures may break the stock lever.
