Car owners had to carry out periodic inspection of the pads in the transmission and at the first sign of oil leaks visiting the service center to eliminate the existing overlap. As a general rule, a serious problem and the need for major repairs occur after driving , kilometers. Repair of modified automatic five-speed transmission F5A51 is performed exclusively with the use of special equipment. In the presence of high-quality diagnostic assistant can easily determine the nature of the failure and eliminate the problem at minimal cost.

Loosen the control cable to the manual control PCM. Ignition start voltage is sent to terminal 10 and lever on transaxle.

Diagnosis here is 3. The TRS can also be checked with the connector 4. You should and turn the TRS body so the hole in the end of have continuity across the terminals shown in the chart the manual control lever and the hole in flange in Figure 20 Less than 2 ohms , related to the position of the TRS body are aligned.

If these do not check properly, Note: The TRS body can be aligned by inserting replace the transaxle range switch. Remove the alignment tool.

The output shaft The Transaxle Range Switch TRS is located on top of is not held and is free to rotate and the engine can be the transaxle, as shown in Figure The TRS is a started. This position can also be selected while the mechanical multi-position switch with four selector vehicle is moving, to restart the engine if that becomes positions on the "Tiptronic" version, seven selector necessary. The Drive position provides control. Refer to Figure 25 for the two versions of the automatic upshifts and downshifts, apply and release of Shift Lever assembly and the TRS wire schematic is the converter clutch, and maximum fuel economy shown in Figure Drive range allows the transmission to operate in each of the five forward gear "Hyundai Only" Selector Lever Positions ratios.

Downshifts are available for safe passing, by P When the "Park" position is selected, there is no depressing the accelerator. The parking pawl On "Tiptronic" models with the shift lever in "D" is engaged which locks the output shaft to the case. The position and moved into the right hand selector gate, it engine can be started and the ignition key can be enables the driver to select the range of gears by tapping removed. Refer to Figure R When the "Reverse" position is selected, the vehicle can be operated in a rearward direction at a reduced gear ProCarManuals.

This position can also be used for engine braking as necessary. Transaxle Range 2 When the "Second" position is selected, the transaxle Switch Assembly will take off in first gear and not allow any shifts above second gear.

L When the "Low" position is selected, the transaxle will take off in first gear and not allow any shifts above first gear. This position can also be used for engine 38 braking as necessary. The BCM illuminates the Reverse lamps.. Ignition start voltage is sent to terminal 10 and out thru terminal 9 to the starter relay. You should have continuity across the terminals shown in the charts in Figure 25 Less than 2 ohms , related to the position of the gear selector lever.

If these do not check properly, replace the transaxle range switch. NOTE: Wire colors may vary. The output shaft The appearance of the selector lever, as shown in is not held and is free to rotate and the engine can be Figure 29, will vary between the different vehicle started. The 2. Ignition lever on transaxle. Place the manual control lever on transaxle in 9 to the starter relay. Diagnosis here is easily done neutral position. You should the manual control lever and the hole in flange have continuity across the terminals shown in the chart of the TRS body are aligned.

Panel Conn. A coil built into voltage at output speed sensor terminal 3. A coil built the input shaft speed sensor generates a 0 - 5 volt pulse into the output shaft speed sensor generates a 0 - 5 volt signal when the input shaft rotates.

The pulse signal pulse signal when the output shaft rotates. The pulse frequency increases with a rise in input shaft speed. The PCM interprets this pulse signal as output speed. The input shaft speed sensor generates the pulse shaft speed. The output shaft speed sensor generates the signal as the teeth on the underdrive clutch housing pass pulse signal as the teeth on the direct planetary carrier the magnetic tip of the sensor. The input speed sensors all operate in the same manner The output speed sensors all operate in the same but all of the PCM terminals are different.

You must manner but all of the PCM terminals are different. You refer to the wiring schematic for the model you are must refer to the wiring schematic for the model you are working on. Mitsubishi wire schematic - See Page Hyundai wire schematic - See Page Kia wire schematic - See Page When a DTC is output four times, the short in the output speed sensor circuit, and a DTC is transaxle is locked into 3rd gear as a failsafe measure.

When a DTC is output four times, the transaxle is locked into 3rd as a failsafe measure. The PCM learns the once per second D1 thru D5 if there are any diagnostic driving habits and the preferences of each individual trouble codes stored related to the transaxle system. The PCM then position indicator D1 thru D5 is flashing once per uses this data to adjust shift timing to best suit the second Requires Scanner.

This applies to drivers style. Mitsubishi Only. The PCM monitors its input and output signals, some Note: If the selector lever position indicator light signals at all times and others only under specified D1 thru D5 is flashing "twice" per second, the conditions. When an irregular signal is initially transaxle fluid temperature is high. Diagnostic trouble codes are kept in memory by direct battery feed. The codes are retained in memory even if ProCarManuals. A compatable scan tool is required to read and erase diagnostic trouble codes.

PCM connector views Page With TCC fully applied pressure should be approximately psi. With DCC fully applied pressure should be approximately psi. The transaxle should be steam cleaned on the technicians.

Attempting repairs or service without the outside, to remove any dirt or grease before appropriate training, tools and equipment could cause disassembly begins. This transaxle can be disassembled very easily The service procedures we recommend and describe on a work bench without the benefit of any in this manual are effective methods of performing holding fixture for rotation.
