ATS Diesel 2007+ Dodge 68RFE Billet Transmission Upgrade Kit - Valve Body and Co Pilot
If you tow heavy with a 2007.5-and-up Ram 2500 or 3500 Cummins on the 68RFE, or you have added a tune and the stock transmission is starting to flare, slip or run hot under load, this ATS billet upgrade kit pairs a reworked valve body with the ATS Co-Pilot controller to raise the line pressure the transmission can produce and hold without the stock hardware working against you.
The 68RFE is a clutch-to-clutch six-speed, and every shift depends on the valve body routing line pressure through its bores and spool valves to the correct clutch pack, timed by the solenoid pack the computer commands. On a stock truck that hardware is sized for factory power and factory towing limits. ATS reseals the accumulator pistons and uses a higher-grade accumulator plate in the valve body so it can physically carry more line pressure without the accumulators blowing out, while the Co-Pilot is a separate transmission controller that commands the TCM to actually produce that higher pressure. Installed together, ATS documents the pair as letting a 68RFE hold roughly 200 horsepower over stock; the valve body alone, with the factory TCM still commanding stock pressure, gives a smaller gain on its own, which is why ATS sells and recommends them as a matched pair rather than either part by itself.
This is a preventive and performance upgrade, not a repair for an already-failed transmission; if your 68RFE is already flaring, slipping or throwing codes on a stock, unmodified truck, diagnose that first with our 68RFE valve body problems and testing guide rather than assuming a billet kit will fix an existing hydraulic fault. ATS's own documentation for this valve body and Co-Pilot combination covers 2007.5 and later 6.7L Cummins trucks running the 68RFE, not the earlier 5.9L-based 48RE, so confirm your engine and transmission combination before ordering.
Built for 2007.5-and-up Ram 2500/3500 trucks with the 6.7L Cummins and 68RFE. ATS's documentation for this specific valve body and Co-Pilot pairing requires the solenoid pack with the white connector already installed in your transmission; the kit itself does not include a solenoid pack. If your truck still has the earlier gray-connector solenoid pack, order a matching 68RFE solenoid kit alongside this upgrade or confirm your connector color before you buy. See the full 68RFE parts collection for every other part sold for this transmission.
Drain the fluid, drop the pan, disconnect the solenoid wiring and swap the valve body, then install the Co-Pilot controller per ATS's wiring instructions and run the transmission's drive-learn relearn afterward rather than driving it normally, since the computer needs to relearn clutch apply timing against the new hardware and the higher commanded pressure. Refill with Mopar ATF+4 only. Because this kit is aimed at towing and tuned trucks, pair it with a deeper, better-cooled pan such as our heavy duty cast aluminum transmission oil pan if you are not already running improved cooling, since the failure modes this kit prevents are heat-driven as much as pressure-driven.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Not necessarily. This is a preventive and performance upgrade for towing and tuned trucks, not a repair kit. If your transmission is already flaring, slipping or throwing codes on a stock truck, diagnose the actual fault first rather than assuming this kit will correct it.
ATS documents the valve body and Co-Pilot as a matched pair. Installing the valve body alone without the Co-Pilot gives only a partial gain, because the stock TCM is not commanding the higher line pressure the reworked valve body can carry. Installing the Co-Pilot alone without the upgraded valve body risks commanding pressure the stock hardware was not built to hold.
No. ATS's documentation for this valve body and Co-Pilot pairing requires the solenoid pack with the white connector already in the transmission. Confirm your connector color, or order a matching solenoid kit alongside this upgrade, before you install it.
This kit is built for 2007.5-and-up Ram 2500/3500 trucks running the 6.7L Cummins and 68RFE, not the earlier 5.9L Cummins trucks with the 48RE. Confirm your engine and transmission combination before ordering.
Mopar ATF+4 only. Refill with ATF+4 after the swap and run the transmission's drive-learn relearn procedure rather than driving it normally so the TCM relearns clutch apply timing against the new hardware.
It is worth considering. The failure modes this kit targets, like clutch slip and converter wear under towing, are heat-driven as much as pressure-driven, so a deeper, better-cooled pan pairs well with this upgrade if you have not already improved cooling.
