68RFE hardening for ~550hp/1150tq?

[patricio2626]

Hello all, first post here. I've perused the forum and Googled a bit, but am still not quite sure about this. I'm purchasing a Calibrated Power EZ Lynk AutoAgent 2.0 for my 2020 2500 Cummins. I see that the "Built Transmission" Race tune is supposed to add 160hp and 300tq. What sort of trans mods would be needed to handle this for very occasional use of all of that power (stoplight challenges)? I asked the sales guy and he mentioned having to drop $10k-$15k to hold this kind of power, which I find suspect. I'm quite sure that there are some here with experience in this area.

A 2500 does not have an Aisin.

Sorry, had silly on the brain. Wish I did have the Aisin in this

If your goal is to tune, then the Aisin is NOT what you want. The RFE has numerous options for billet parts, and tuning out there, and can be built to hold pretty big power.

You are going to want a trans tune, an a modified Valve body that can hold higher line pressures at the least.

if you plan on having "fun" with it, you'll need more than a valve body for longevity.
