Help making a valve body decision

[Gus]

Hi guys, I am getting ready to pull the trigger on a valve body. I have the 68rfe and we tow our RV a lot, up mostly mountain grades. I know my transmission is one of my weak links and I am trying to help improve it. I am in the market for a valve body and I am a little undecided and can sure use your advise, suggestions or thoughts.

Here are the 4 that I am considering:
1) revmax
2)Randy's
3)Sonnax
4)ATS

I wasn't sure if my trucks info shows up on my posts but I am running a 2014 2500, crew cab, short bed, 6.7 Cummins, 68rfe behind it, all stock.

My 2014 2500 68rfe torque converter lockup went out on me a few months back. After calling revmax I ended up ordering a 550 68rfe with billet input shaft and flexplate.

Revmax will credit the valvebody purchase towards a built transmission if you go that route in the future.

Oh that’s great to know, thanks for that info.

Have about 3,000 miles with the revmax and Calibrated Power tuning. Was pricey but runs and shifts GREAT!!! Feels like a new truck

I’m wondering if it’s worth changing the valve body if I am not planning on doing any trans tuning? Is it worth doing?

In your position with a stock truck I would leave it alone. Plenty of stock trucks running 100's of thousands of miles with no issues. The trans is the weak link for guys running higher HP tunes, not so much on a stock truck.

You an try and just have the trans tuned to your liking. Different shift points, high fluid pressures. No nee to tear into the trans to do so.

Thanks for all the feedback everyone. I started thinking about this as I was traveling north on 395 in California. If you have even been on that road climbing the hill from the owens valley when it’s 110 outside and hauling our camper. The tranny wasn’t too happy. I could feel the trans working a little different. Slower response. It didn’t get crazy hot and at near our destination I had 2 tiered go out of round and then a failure in a heater hose Y pipe. So after going though all that with my wife and little boys with me, whatever I can do the make the truck reliable I am happy to do.

Based on many local's experiences, avoid ATS.

Been up that long steep grade on the 395 in a F250 with V10 and 4.30 gears pulling a small trailer with 2 quads. Pain in the butt.

I've put my stock 23 2500 to work hauling RVs & been wondering about this myself. As far as I know, Randys & ATS are the 2 who offer a VB without tuning. Although ATS suggests using there "copilot" with there VB. I haven't really found any solid reviews on either one (without tuning), good or bad. Hopefully someone here running one of these two can lend there experience.
