TORQUE SPECIFICATIONS

The transmission fluid cooling system, without an auxiliary transmission fluid cooler, consists of

  1. an in-tank fluid cooler inlet tube.
  2. a non-repairable in-tank transmission fluid cooler.
  3. an in-tank fluid cooler return tube.

The transmission fluid cooling system, with an auxiliary transmission fluid cooler, consists of

  1. an in-tank fluid cooler inlet tube.
  2. a non-repairable in-tank transmission fluid cooler.
  3. fluid cooler hoses.
  4. hose clamps.
  5. an auxiliary transmission fluid cooler.
  6. a fluid cooler return tube.

The transmission fluid flows from the transmission (front fitting for TorqShift®, bottom fitting for the 4R75E), to the in-tank transmission fluid cooler, to the auxiliary transmission fluid cooler (if equipped) and returns to the transmission (rear fitting for TorqShift®, top fitting for 4R75E).

For the Transmission Fluid Cooler Backflushing and Cleaning procedures, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 4R70E/4R75E or AUTOMATIC TRANSAXLE/TRANSMISSION - TORQSHIFT .

Inspection and Verification

Note. When internal wear/damage occurs in the transmission, metal particles, clutch plate material and band material can travel into the torque converter, the transmission fluid cooler tubes, the in-tank transmission fluid cooler and the auxiliary transmission fluid cooler, if equipped. These contaminants are a major cause of recurring transmission concerns. To prevent future concerns, remove these contaminants from the cooling system before placing the transmission back into use. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 4R70E/4R75E or AUTOMATIC TRANSAXLE/TRANSMISSION - TORQSHIFT for the Transmission Fluid Cooler Flow Test, Transmission Fluid Cooler Backflushing and Cleaning and Torque Converter Contamination Inspection procedures.

  1. Visually inspect for obvious signs of mechanical damage, incorrect component installation and system leaks. Repair as necessary. Install a new or remanufactured radiator when transmission fluid is found leaking from the in-tank transmission fluid cooler. Refer to «ENGINE COOLING»(/ford/econoline-e250/2012-2013/remont/cooling-system-mechanical/#engine-cooling-system) . Install a new O-ring seal when transmission fluid is found leaking between the radiator transmission fluid cooler and the transmission fluid cooler fitting (not the cooler tube into the fitting). Refer to «COMPONENT TEST»(/ford/econoline-e250/2012-2013/remont/automatic-trans/#automatic-transmission-cooling-system) . Install a new auxiliary transmission fluid cooler if there is leakage from the auxiliary transmission fluid cooler, and always as part of a transmission overhaul or exchange. Refer to «AUXILIARY TRANSMISSION FLUID COOLER»(/ford/econoline-e250/2012-2013/remont/automatic-trans/#automatic-transmission-cooling-system__auxiliary-transmission-fluid-cooler) .
  2. If the fault is not visually evident, GO to «SYMPTOM CHART»(/ford/econoline-e250/2012-2013/remont/automatic-trans/#automatic-transmission-cooling-system__symptom-chart-transmission-cooling) .

SYMPTOM CHART - TRANSMISSION COOLING

Symptom Chart - NVH

Note. NVH symptoms should be identified using the diagnostic tools that are available. For a list of these tools, an explanation of their uses and a glossary of common terms, refer to NOISE, VIBRATION & HARSHNESS . Since it is possible any one of multiple systems may be the cause of a symptom, it may be necessary to use a process of elimination type of diagnostic approach to pinpoint the responsible system. If this is not the causal system for the symptom, refer back to NOISE, VIBRATION & HARSHNESS for the next likely system and continue diagnosis.

ConditionPossible SourcesAction
Vibration - a high frequency (20-80 Hz) that is felt through the seat or selector lever. Changes with engine speedTransmission fluid cooler tubes grounded outCHECK the transmission fluid cooler tubes. REPAIR as necessary. REFER to TRANSMISSION FLUID COOLER TUBES - 4R70E, 4R75E or TRANSMISSION FLUID COOLER TUBES - TORQSHIFT .

Transmission Fluid Cooler Leaks at Radiator

Transmission fluid may leak between the radiator in-tank transmission fluid cooler and the transmission fluid cooler fitting (not the transmission fluid cooler tube into the fitting), which may result in a residue of transmission fluid on the radiator tank around the transmission fluid cooler fitting. This may be caused by insufficient thread sealer on the transmission fluid cooler fitting.

  1. Clean the area around the transmission fluid cooler fittings.
  2. Verify that transmission fluid is leaking between the transmission fluid cooler tube fitting into the transmission fluid cooler (not the transmission fluid cooler and the transmission fluid cooler fitting). Inspect the rubber transmission fluid cooler hose and the transmission fluid cooler fitting clamp. If the leak is at the transmission fluid cooler fitting, install a new transmission fluid cooler fitting clamp or the transmission fluid cooler hose.
  3. If the leak is at the transmission cooler fittings, install a new radiator. Refer to «ENGINE COOLING»(/ford/econoline-e250/2012-2013/remont/cooling-system-mechanical/#engine-cooling-system) .
