OK. 08 f350 with 12 valve cummins,
Just upgraded to stage 2 EPC and direct Solenoids to reduce shift flare. 1-2, 2-3 shifts are nice crisp and firm. 3-5 shift harsh almost shudders under light throttle, 1/2 throttle or more its ok. I havent been able to figure out how to tune it out. What clutches control which shifts? have not been able to find much info on tuning a 5r110, any help would be greart...TIAScreenshot (23).pngScreenshot (22).png
