    I've got a customer that just has the VB from Revmax in his 2015. Before he even loaded the tune with the higher line pressure setting, he said just the VB made a big difference. He said it was even better after the tune.

    Ray maybe you can explain from a tuners point of view things that you can do different or better with the valvebody in place and we can form an opinion on if we would like to get one or not.

    I agree with Ray, IMO it's a lot smoother through the shifts than stock.

    The stock valve body will open its pressure relief in the forward gears anywhere from 165-180psi...depending on individual transmission. Most will do 170 psi and a few will tickle 180psi in the forward gears. Also keep in mind I'm talking a sustained amount of pressure, not a spike caused by fluid being thrown around during a shift. Also, I'm not talking about reverse either...as reverse can easily hit 250psi within its hydraulic circuit.

    As a tuner, I can tell the tune to command as high as I want, but you can never exceed the mechanical limitation set by the valve body pressure relief. The aftermarket/modified valve body raises the mechanical limitation. Once this is done, I can then change the tuning which will command a higher pressure that will be achieved because of the mechanical modification.

    OK, what does higher pressure do? Higher pressure does 2 positive things. It holds clutches together with more clamping force, which reduces slippage and wear. It also speeds up all the hydraulic processes within the transmission, which means crisper shifts and lockup. Higher pressure does have a downfall in that it can increase fluid temperature, but keeping the trans fluid changed every 25-30k miles is all that is needed to prevent problems from heat related fluid breakdown.

    Swapping out the VB isn't mandatory if you are gonna keep a mild tune on the truck, but it is a worthwhile modification.

    Re: Revmax valve body for a 68 worth it?

    Does the line pressure increase as the transmission gets worked harder or is it always applying 225 psi once the revmax is installed and tuned?

    Rhino, I'm not really looking for anything, just asking questions to those in the know on transmissions. I know a bit about trucks, but squat about transmissions. Currently, I pull a 40' camper and a 18' boat. This might be the last diesel I own. The wife and I bought a lot on the big lake in ND, with water access, so I won't be lugging around a camper and boat after another five years or so. Once my kids get older, they won't care about a place to bike or a playground; they will just want to be on the water. The lot will be perfect once that time comes.

    I have a bit of a bucket list. One thing I always wanted to do was build a truck with a decent amount of power and be able to use that power (stupid waste of money, but I'm a typical guy and farm kid). My truck is currently tuned, and I want to be able to use that power safely from time to time. I'm just curious if that valve body will enable me to do so. I would love to install the add a turbo kit from Hardway, but my wife would tell me I'm an idiot (bucket list thing). I've been looking for a used add a turbo kit so I can justify (con) it to the wife, but I haven't found anything.

    Blah, blah

    Merry Christmas, and thanks for all the help.

    I plan to have the tranny serviced with a bit over 41,000 miles (pull with the truck). I think I will go ahead and have the revmax valve body installed. I'm going to own this truck for awhile. It's a relatively small chunk of change over five plus years.

    Do I go straight through revmax to purchase the valve body or do other vendors sell it for a bit less on this forum?
