Pinpoint Tests 3.5L Ti-VCT

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Carry out OBD procedures KOEO and KOER .
Retrieve and record all DTCs.
Repair all non-transmission DTCs first.
Repair all transmission DTCs second.
Clear all continuous codes and attempt to repeat them.
Repair all continuous codes.
If only pass codes are obtained, refer to Component Tests for additional transmission component information and diagnosis.

Power is routed through the transmission solenoid power control relay (inside the PCM) to all transmission solenoids. If the power circuit to the transmission solenoids or the transmission solenoid power control relay fails open, all solenoids are failed electrically off. Check for open, short to ground or the transmission connector disconnected. The transmission solenoid power control relay disables power to the transmission solenoids when certain transmission DTCs are set.

NOTE: Without a voltage signal return to the PCM, the transmission solenoid power control relay is commanded off. By using a fused jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that may be at fault, refer to DTC Charts for a fault listing.

Follow the diagnostic sequence to diagnose and repair the concern the first time.

Refer to Wiring Diagrams Cell 29 , Transmission Controls - 6F50/6F55 for schematic and connector information.

Normal Operation and Fault Conditions

The TFT sensor is located in the transmission solenoid body. The resistance value of the TFT sensor varies with temperature change. The PCM monitors the voltage drop across the TFT sensor to determine the temperature of the transmission fluid. When the ignition is turned to the RUN position, this initial input signal is used by the PCM to determine whether a cold start shift schedule is necessary. The cold start shift schedule allows delayed shifts when the transmission fluid is cold. The PCM inhibits TCC operation at low transmission fluid temperatures and adjusts line pressure to temperature.

Line Pressure Test

Item	Service Part Number	Description
1	7A010	Line pressure tap
2	7A010	Transmission fluid drain plug

NOTICE: Carry out the Line Pressure Test prior to carrying out the Stall Speed Test. If the line pressure is low at stall, do not carry out the Stall Speed Test or further transmission damage will occur. Do not maintain WOT in any transmission range for more than 5 seconds.

NOTICE: Do not mistake the transmission fluid drain plug for the line pressure tap plug or the transmission fluid will have to be refilled.

This test verifies the line pressure is within specification.

Connect the transmission fluid pressure gauge to the line pressure tap.

Start the engine and check the line pressure. Refer to the Pressure Chart to determine if the line pressure is within specification.

Pressure Chart

Gear	Line Pressure at Idle KPa (psi)		Line Pressure at WOT Stall KPa (psi)

Stall Speed Test

WARNING: Block all wheels, set the parking brake and firmly apply the service brake to reduce the risk of vehicle movement during this procedure. Failure to follow these instructions may result in serious personal injury.

The Stall Speed Test checks:

torque converter operation and installation.
holding ability of the forward clutch.
holding ability of the low/reverse clutch.
OWC .
engine driveability concerns.

Conduct this test with the engine coolant and transmission fluid at correct levels and at normal operating temperature.

Apply the park brake firmly for each Stall Speed Test.

Stall Speed Chart

Engine	Stall Speed
3.5L Ti-VCT	2,100-2,600
3.5L GTDI	2,200-2,500

Connect the scan tool.

NOTE: If the recorded rpm exceeds the maximum limits, release the accelerator pedal immediately because clutch slippage is indicated.
In each of the following ranges Drive, Low and Reverse, press the accelerator pedal to the floor and hold it just long enough to let the engine get to WOT . While conducting this test, do not hold the throttle open for more than 5 seconds each time.

Record the results in each range.

After each range, move the selector lever to NEUTRAL and run the engine at 1,000 rpm for about 15 seconds to cool the torque converter before conducting the next test.

Use the Stall Speed Diagnosis Chart for corrective actions.

NOTE: The stall speed in REVERSE will be lower.
If stall speeds were too high, see the Stall Speed Diagnosis Chart. If stall speeds were too low, first check engine idle speed and tune up if necessary. If engine is OK, install a new torque converter.

Range	Possible Source
D, L	Forward Clutch, Low/Reverse Clutch, Low/ OWC
R	Low/Reverse Clutch, Direct Clutch

Leakage Inspection

NOTE: When diagnosing transmission leaks, the source of the leak must be positively identified prior to repair. If the vehicle is driven extensively between adding the fluorescent additive and performing the leak test, the leaking oil can spread and make identifying the location of the leak difficult.

Clean the top and bottom of the torque converter housing, the front of the transmission case and rear face of the engine and oil pan. Clean the torque converter area by washing with a nonflammable solvent and blow dry with compressed air.

Add Dye-Lite® ATF Power Steering Fluid Leak Detection Dye to the transmission fluid. Use one 30 ml (1 fl. oz) of dye solution for every 3.8 L (4 qt) of transmission fluid.

Start and run the engine until the transmission reaches its normal operating temperature. With the engine running, raise the vehicle on a hoist and occasionally shift to the DRIVE and REVERSE ranges to increase pressure within the transmission. Using a black light, observe the back of the cylinder block and top of the torque converter housing for evidence of fluid leakage. Run the engine until transmission fluid leakage is evident and the probable source of leakage can be determined.

If the source of the leak is obvious, repair as required. Leaks from the torque converter housing can originate from several locations. The paths which the fluid takes to reach the bottom of the torque converter housing are shown in the illustration. The 5 following steps correspond with the numbers in the illustration.
1. Transmission fluid leaking by the converter hub seal lip tends to move along the drive hub and onto the back of the torque converter. Except in the case of a total seal failure, transmission fluid leakage by the lip of the seal is only deposited on the inside of the torque converter housing, near the outside diameter of the housing.
1. Transmission fluid leakage by the outside diameter of the converter impeller hub seal and the case follows the same path that leaks by the ID of the converter hub seal.
1. Transmission fluid leakage from the converter cover weld or the converter-to-flexplate stud weld appears at the outside diameter of the torque converter on the back face of the flexplate and only in the converter housing near the flexplate. If a converter-to-flexplate lug, lug weld or converter cover weld leak is suspected, remove the torque converter and pressure check.
1. Transmission fluid leakage from the bolts inside the torque converter housing flows down the back of the torque converter housing. Leakage may be from loose or missing bolts.
1. Engine oil leaks from the rear main oil.

Remove the torque converter.

Using a black light, observe the torque converter housing. Inspect for evidence of dye from the pump bolts, pump seal and torque converter hub seal. Repair as required.

If the source of the leak is not evident, continue with this procedure to leak test the torque converter.

Install the torque converter in the arbor press. Support the torque converter on the mounting pads.

Install the Leak Tester, Torque Converter 307-421 into the torque converter hub.

Secure the press. Only apply enough force from the press to seal of the Leak Tester, Torque Converter 307-421 into the torque converter hub.

Connect a compressed air supply to the Leak Tester, Torque Converter 307-421.

With air pressure applied to the valve, inspect for leaks at the converter hub weld and seams. A soap bubble solution can be applied around those areas to aid in the diagnosis. If any leaks are present, install a new torque converter.

With air pressure applied to the valve, inspect for leaks at the stud or mounting pad and balance weight welds. A soap bubble solution can be applied around those areas to aid in the diagnosis. If any leaks are present, install a new torque converter.

After leaks are repaired, clean remaining transmission fluid dye from serviced areas.
