5R110W TRANSMISSION WONT SHIFT OUT OF 1ST FREE

The output shaft is free to turn, and the engine can be started. N – In Neutral, there is no power flow through the transmission.R – In Reverse, the vehicle can be operated in a rearward direction at a reduced gear ratio.The engine can be started and the ignition key can be removed. The parking pawl is engaged, locking the output shaft to the transmission case. P – In Park, there is no power flow through the transmission.

The TorqShift transmission has seven range positions that can be selected with the manual shift lever: P, R, N, (D), 3, 2, 1. Do not try to back-flush and clean the OTA cooler. Ford recommends replacing the OTA cooler as part of any overhaul or exchange. This unit is equipped with an oil-to-air (OTA) cooler in front of the radiator. The remote filter in the cooler lines also should be replaced at each service interval. The filtered fluid then is directed back into the rear lube circuit through the large opening in the remote-filter manifold. This filter passes 10% of the fluid through a small orifice into a serviceable screw-on filter element.

This transmission also is equipped with a new remote fluid filter. Ford recommends replacing the fluid and bottom-pan filter every 48,000 km (30,000 miles) regardless of normal or special operating conditions. The use of any fluid other than Mercon SP can result in abnormal operation and/or transmission failure. The new transmission also uses a new fluid called Mercon® SP, which is not interchangeable with Mercon® or Mercon® V. All transmission gear ranges, including all five forward gears, are available when using the tow/haul feature.

Another new feature on this unit is called the tow/haul mode, which is designed to assist the driver when towing a trailer or a heavy load. The current is varied between 0 and 1 amp from the PCM, and 0 amp equals maximum pressure in the oil circuit.Īdded to the instrument cluster is a transmission temperature gauge that we think is long overdue. Three of the solenoids – line pressure, coast clutch and direct clutch – are inversely proportional, meaning the pressure output is inversely proportional to the applied DC current. The current is varied between 0 and 1 amp from the PCM, and 1 amp equals maximum pressure in the oil circuit. Four of the solenoids – TCC, OD clutch, intermediate clutch and the low/reverse clutch – are directly proportional, meaning the pressure output is directly proportional to the applied DC current. Line pressure and the torque-converter clutch each have their own dedicated solenoid. There are no other shuttle valves in the solenoid body.įive solenoids control all shifts. A solenoid and a pressure switch are dedicated to the function of each clutch pack, except the forward clutch, which is controlled by the manual valve. This is due to a total redesign of the control valve body. There were no lags between shifts, and every shift was very positive. Looking for more technical transmission info like this?

In hot mode the transmission will shift 1st, 2nd, 3rd, 5th (ratio 1.00), 6th. All sound familiar? In cold mode (below -15☌ (5☏), determined by the transmission-fluid-temperature sensor), the overdrive clutch is engaged in 3rd gear to provide a ratio of 1.09 for 4th gear, and the transmission will shift directly from 4th to 6th gear (overdrive), which has a ratio of 0.71. 3rd gear provides a ratio of 1.54, the same as the 4R100’s second gear. For 2nd gear the overdrive clutch is applied to provide a ratio of 2.20. The ratio for 1st gear was changed from 2.71 to 3.09. The TorqShift is a five-speed, rear-wheel-drive unit that actually has six forward speeds with ratios depending on whether the transmission is operating in hot or cold mode.
