Key internal upgrades include upgraded clutch packs, a SunCoast Valve Body Calibration Kit, and a Mag-Hytec Deep Pan. The 5R110 TorqShift 5-speed transmission, introduced in 2003 with the 6.0L diesel engine and later used with the 6.4L, includes adaptive shift control and a Tow/Haul mode. SunCoast's design addresses common issues like center support distortion and direct clutch problems, ensuring accurate and crisp shifts. A billet flexplate is recommended for optimal reliability at this power level.
