[QUOTE="DILLARD000, post: 1051560, member: 74901"] Welcome to the Herd; lots of friendly knowledgable folk in these forums. Your 2004 SportTrac has the V6~4.0L~SOHC Engin, not the V6~4.0L~OHV. Completely different incompatible engines; swap requires moving Electronics + Harness + Computer\PCM +... along with Engin from donar vehicle to the 2004 ST. 1998 controls are also likely not compatible with the 2001+Later version of the 5r55e Trans in the 2004 ST (different Transmission sensor arrangement & housing) so older Trans would be needed in the swap. Assuming your 2004 V6~4.0L~SOHC Engin &\or 5r55e Trans are shot & need to be replaced\rebuilt? Might make more sense to rebuild what you have or find suitable newer lower mileage 2001~2012 replacements. I'd avoid any V6~4.0L~SOHC block 2002 or older due to FailureProne TimingTensioner+Guide design. You need a 2001 or newer 4WD version of the 5r55e Trans. [/QUOTE]
