A torque converter in a Ford F-350 is the sole link between the truck's engine and transmission. As such, it is located between the two components, and requires removing the entire transmission to access. The installation process takes approximately four hours to complete.
Disconnect the negative battery cable. Raise the vehicle off the floor using a hydraulic floor jack and jack stands.
Remove the driveshaft yoke bolts and lower the rear end of the driveshaft. Slide the driveshaft out of the rear of the transmission.
Disconnect the transmission shift linkage, fluid cooler lines, speedometer cable and wiring harness connectors. Support the transmission from beneath with a floor jack. Remove the transmission bellhousing to engine block bolts and slide the transmission backward as much as possible. Pull the old converter off of the transmission input shaft.
Fill the new converter with one quart of fresh transmission and slide it onto the transmission input shaft. Rotate the converter left and right as you slide it onto the input shaft. Three distinct clicks should be heard as the converter engages the outer input shaft, inner lockup shaft and front pump.
Perform steps one through three in reverse order to reassemble the drivetrain.
