You will no longer be lugging gears with over sized tires on your truck. We specifically make “purposed built” trans tuning for your tire size and gear ratio. We aim to sell smooth controlled transmission tuning to keep your transmission reliable for years to come! We have the capability to keep OEM Part lock TC behaviors or upgrade them to Locked Shifts to remove the TC "flare" feel during the shifts. On top of that, Torque converter firmness can be kept in a stock feel or enhance to a firm early lockup. We have options to lock in 2nd, 3rd, or 4th gear. Our highest seller is 3rd TC Stock feel. If you are looking to put all the power to the ground with a 68RFE. Look no further, we can achieve that for you with locked shifts.
Locked Shifts in Detail, What is Locked Shifts? The 68RFE has been a very delicate transmission in Chryslers eyes. In order to keep it jello, Chrysler decided to "partially lock" the Torque Converter DURING the shifting event. This takes strain off the clutches inside your transmission and really cushions the shifts for the hard parts. In doing so, some may notice a rise in RPM during the shift. - Almost like a slip/flare feel. This is the TCM going into a partial lock up state to jello the shift, it also comes really apparent on worn transmissions with slow to bleed off pumps. 2013-18 trucks are really bad at feeling this effect. In order to solve this annoying rise in rpm, we use Locked Shifts. The earlier 07-12 trucks were "tighter" for the Partial lockup, meaning locked shifts are not really required as they feel OK. 2019+ trucks, Chrysler made the partial lock up tighter like the 07-12 trucks again.
Another reason to keep partial lockup is if you Tow Heavy or plan to run high HP tuning with a stock transmission. This will allow smooth shifting and allow the transmission to live a longer. Under 120HP, We recommend locked shifts on the 13-18 trucks. Ideally its your choice.
We add Line pressure when and where needed within the calibration. Our TCM tuning is compatible with all large name Transmission building companies. whether you’re running a stock valve body(180PSI) or aftermarket (225PSI). We provide TCM files specifically to your build/request.
