Ford Contour FIT408

FIT408 is a two part fitting that requires an O-ring seal to

the transmission line.

CAUTION: These fittings are a matched set and must be

kept together in the small plastic box marked FIT408.

Instructions

1. Remove the transmission cooling line from the

radiator.

2. Attach the female portion of FIT408 to the

transmission cooling line.

3. Attach the male portion of FIT408 to the radiator

(see Figure 58).

Ford Escort FIT401

CAUTION: These fittings are a matched set and must be kept

together in the small plastic box marked FIT401.

Instructions

1. Remove the vehicle bolt, fitting and crush washers from

the radiator.

2. Install the

T-TECH female half to the stock bolt and

washers.

3. Install the

T-TECH male half into the radiator using the

white nylon gasket (supplied) (see Figure 59).

4. After T-TECH service is complete, remove the fittings and

store in FIT401, reinstall factory parts and start the engine.

Check for leaks and fluid quantity.

Ford Explorer

Many 2001 to 2006 Ford Explorer and Mercury Mountaineer models have an internal thermostat that controls the

flow of the fluid to the cooler. This thermostat solenoid remains closed until the vehicle reaches proper operating

temperature (140°F). There is no bypass or pressure relief mechanism in this solenoid that can be forced open. This

situation will result in low or no flow of transmission fluid to and though the

T-TECH, causing delays in service

times.

The following procedure is recommended to improve service times on the above vehicles:

1. Connect the

T-TECH to the vehicle (varies by model).

2. Start the vehicle, set the parking brake and with foot on brake, place in neutral increasing engine speed to

1600 RPM.

3. When the transmission fluid reaches 140°, the solenoid will open and the fluid will start to flow through the

cooler lines and to the cooler.

4. Continue to keep a foot on the brake, maintain the engine at 1600 RPM and the vehicle in neutral to

maintain optimum transmission fluid temperature and flow.

5. If no fluid flow occurs, use a non-contact thermometer and check the temperature of the transmission pan.

If not at 140° raise the engine speed to 1900 RPM to increase the transmission temperature.

6. If the fluid temperature is at or above 140° and fluid does not flow, stop the process. In some cases, the

thermostat or solenoid valve may be defective (not allowing fluid flow) and need servicing. Inspect the

transmission fluid condition and if the fluid is extremely burnt it may indicate a defective thermostat or

solenoid. This must be remedied before a service can be performed.

7. To ensure correct fluid level, always check the fluid level prior to vehicle leaving the bay. Refer to Sealed

Transmission service guidelines below.
