TRANSMISSION APPLICATION
| WARNING | Before removing engine/transmission assembly on compressed natural gas powered vehicles, see safety precautions in the COMPRESSED NATURAL GAS SAFETY PRECAUTIONS article in GENERAL INFORMATION section. |
| CAUTION | On vehicles equipped with electrical air suspension, power to air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. The air suspension switch is located behind right kick panel area. Failure to do so can result in inflation or deflation of air springs, which may cause vehicle to shift during these operations. |
| CAUTION | When battery is disconnected, vehicle computer may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See the COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section before disconnecting battery. |
Scheme 1
- Place transmission in Neutral. Disconnect negative battery cable. Remove dipstick. Raise and support vehicle. On 4WD vehicles, remove skid plate and transfer case. See TRANSFER CASE article in TRANSFER CASES. Mark drive shaft(s) and axle flange or yoke for reassembly reference. Remove drive shaft(s).
- Disconnect oil cooler lines and filler tube from transmission. Plug all oil cooler line openings. On F350 Super Duty commercial chassis, disconnect speedometer cable from parking brake assembly. (Scheme 1) Loosen lock nut on parking brake cable at clevis. Remove clevis pin, clevis, and lock nut from parking brake cable. Remove parking brake cable from bracket on parking brake assembly.
- On all models, disconnect control cables, shift linkage, and speedometer cable from transmission. On 4WD models, remove shift linkage from transfer case (manual shift models), or unplug connector at transfer case (models with electronic shift). Unplug 4WD switch connector from transfer case. Detach wiring harness from retainers on frame rail.
- On all models, remove necessary heat shields for access to electrical connectors. Unplug connector from Transmission Range (TR) sensor, mounted at shift lever on transmission. Unplug connector from solenoid assembly on side of transmission. CAUTION: Remove electrical connector from TR sensor by squeezing tabs together and pulling connector from TR sensor. Remove electrical connector from solenoid assembly by pushing inward on center tab. DO NOT pry on tab(s) with screwdriver.
- Loosen oil pan bolts to allow fluid to drain. When fluid stops draining, remove all but 2 bolts at front of oil pan. Allow oil pan to drop. Drain remaining fluid. Reinstall bolts to hold oil pan in place.
- Remove torque converter cover. Remove starter motor. Remove torque converter-to-drive plate nuts. Support transmission with floor jack. Remove transmission mount-to-crossmember nuts and crossmember-to-frame bolts.
- Remove crossmember. Secure transmission to floor jack with safety chain. Remove transmission-to-cylinder block bolts. Move transmission rearward and lower from vehicle.
- On F350 Super Duty commercial chassis, remove parking brake assembly, remove retaining bolts, parking brake assembly, and gasket if necessary. (Scheme 1)
| CAUTION | Store parking brake assembly with breather assembly facing upward to prevent oil leakage onto brake shoes. |
- To install, reverse removal procedure. Use NEW "O" ring on filler tube. Ensure torque converter is fully seated. Align reference marks on drive shaft and axle flange or yoke.
- On F350 Super Duty commercial chassis, use NEW gasket and retaining bolts when installing parking brake assembly. DO NOT reuse bolts. On all models, tighten all bolts/nuts to specification. See «TORQUE SPECIFICATIONS»(ref-61330-S31263941572001100200000) table. CAUTION: Pickup F350 Super Duty commercial chassis parking brake assembly contains a separate reservoir from transmission. Check lubricant level at filler plug hole on side of parking brake assembly. Fluid level should be even with bottom of filler plug hole. Add Motorcraft Mercon ATF (XT-2-QDX) as needed.
- Fill transmission with appropriate transmission fluid. For fluid type, capacity and control cable or linkage adjustment, see the TRANSMISSION SERVICING - A/T article.
