Most valve bodies now a days dont need the added aid of a pressure loc due to the advancements made in the boost valve circuit, throttle valve circuit and the switch valve circuit.
There are some aftermarket valvebodies that run low line pressures that will benefit from the aid of the pressure lock.
The pressure loc gives you increased line pressure at the low throttle positions, once you get to about 60% of your throttle and above you basically return to whatever your original pressures were without the pressure loc.
In other words if originally had a pressure of 100 psi, you will still have a pressure of 100 psi.
Hm,
Multi disc clutch topic again, interesting .
If when considering a product and you dont know the proper questions to ask you could find yourself in a little bit of trouble.
When you are seeking product information and you dont know the answer then the answer you are given really doesnt mean anything .
Here is an analogy for you, if you owed a standard transmission and you constantly rested your foot on the clutch, would the clutch last a long time? or do you think you would be shortening the life by doing so.
On an automatic the tc clutch is released by hydraulic oil, the moment you start your truck up hydraulic oil (atf) pushes the clutch piston away from the front cover towards the turbine. If you have multiple disc clutches you are actually hydraulically applying the lock up clutch as the lock up clutch fibres are being squeezed by the atf.
2 of the 3 clutch fibres are on all the time the moment you start your truck up till you shut it off. They are constantly being dragged, this will result in premature failure. By the time the average person even figures out what is going on, they will not only have contaminated their transmission but they would be looking at contamination of the heat exchanger and the transmission cooler. It could turn out to be a expensive repair bill.
You wont get much warning till the truck just up and quits.
We have been down many roads and discarded many ideas along the way, the best advice i can give you guys out there is to keep your rpms high , pressures up, and use lock up devices with care .
