Trintity U7137 1r07d


My question is regarding the shift points. I bought a 5.7 w/ 3.55's, I know...my mistake! I am wondering if I can use the shift points in the Trinity to keep the truck in the higher RPM range to better mimic a lower gear ratio and get a little more "lugging" power?

I haven't jumped into the experimenting with shift point changes yet, only looked at the screen for making the adjustments. Looks a bit confusing with the way the upshift 1-2 and part throttle up shift ect. are setup.

Anyone have good number to start with or are there any 5.7 Hemi savy techs out there that can point me down the path of least resistance and save me a lot of heartache and time?

I'da 'preciate it!

Thanks fellas.

Nuke, the only way to achieve what you desire is to either use ERS to stay in 4th gear, or force the torque converter clutch to slip. Running in 4th will hurt your fuel economy in most cases, and there is no easy way to force the TCC to slip - not to mention that even if you made it slip, it'd just wear it out sooner.

My Ram 4x4 has the 3.55s as well, and I have been doing some research in trying to decide between 3.92s or 4.10s, but either way, upgrading the gears themselves is not that expensive or difficult. But if you're going to uprade the gears, you'll want to upgrade to a limited slip or locker too, and those are pricey.

If you have a 4x2, you only need one gear set, which can save you some money.

To get a complete set of gears (front and rear diff) for my 4x4, with the installation and shim kits, and a LSD unit, it would cost me about $1100 from 4WheelParts.com. The gears could be installed in an afternoon.
