DESCRIPTION

4R70W is a 4-speed, automatic with electronic shift, converter clutch and line pressure controls. It uses a double-pinion compound gearset to produce 4 forward speeds and reverse. It uses 2 bands, 2 one-way roller clutches and 4 friction clutches to hold or drive the planetary gearset members. (Scheme 42)

Shift control solenoids provide gear selection and are controlled by the EEC microprocessor. For additional information on the EEC system, see SELF-DIAGNOSTICS - EEC-V article in ENGINE PERFORMANCE.

The EEC system has self-diagnostic capabilities. Fault codes for faulty engine and transmission sensors, switches and circuits are stored in the PCM and may be retrieved to aid diagnosis and repair.

CLUTCH & BAND APPLICATIONS

CLUTCH & BAND APPLICATIONS

ROAD TEST

1. Drive vehicle with transmission in "OD" position at normal operating temperature. Check minimum throttle upshifts in "OD". Transmission should start in 1st gear and shift to 2nd, 3rd, and 4th gear at approximate speeds shown in «SHIFT SPEED SPECIFICATIONS»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission__shift-speed-specifications) .
2. With transmission in 4th gear (overdrive), press Transmission Control Switch (TCS). Transmission should downshift to 3rd gear. Release accelerator pedal. Engine braking should occur.
3. Press accelerator pedal to WOT. Transmission should shift from 3rd to 2nd gear, or 3rd to 1st gear depending on vehicle speed. Torque converter clutch should disengage and then reapply.
4. With transmission in "OD" position, and vehicle speed more than 50 MPH, move transmission selector lever to manual "2" position. Release accelerator pedal. Transmission should immediately downshift to 2nd gear. Move transmission selector lever to manual "1" position. Transmission should downshift to 1st gear at speeds less than 30-35 MPH.
5. If transmission fails to operate normally or torque converter does not apply and release properly, diagnose problem by symptom. See «SYMPTOM DIAGNOSIS»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission__symptom-diagnosis) under TROUBLE SHOOTING.

HYDRAULIC PRESSURE TEST

Note. Pressure test at idle position must be taken with engine at normal operating temperature. Pressure test at WOT position should be taken at full stall speed conditions. Run engine at a fast idle in "N" position for 15 seconds to cool fluid between tests.

Line Pressure Test

1. Connect a 0-300 psi (0-21.1 kg/cm 2 ) pressure gauge to line pressure tap on left side of transmission case forward of control lever. (Scheme 52) Gauge hose must be long enough to read gauge while operating engine.
2. With engine at normal operating temperature, apply parking and service brakes. Check line pressure at idle and WOT stall in all ranges. See «HYDRAULIC PRESSURE SPECIFICATIONS»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission) table. If pressure is not as specified, perform «EPC PRESSURE CHECK»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission__epc-pressure-check).

EPC Pressure Check

1. Connect a 0-100 psi (0-7.0 kg/cm 2 ) pressure gauge to EPC pressure tap at right side of transmission case. (Scheme 52) Gauge hose must be long enough to read gauge while operating engine.
2. With engine at normal operating temperature, apply parking and service brakes. Check EPC pressure at idle and WOT stall in all ranges. See «HYDRAULIC PRESSURE SPECIFICATIONS»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission) table. If pressure is not as specified, see «TEST D: ELECTRONIC PRESSURE CONTROL (EPC) SOLENOID»(/ford/econoline/i-1985-2013/remont/automatic-trans/#diagnosis-4r70w-automatic-transmission) under SYSTEM TESTS in FORD 4R70W ELECTRONIC CONTROLS article, to diagnose EPC operation. If EPC operation is okay, go to «LINE PRESSURE TEST RESULTS»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission).

Scheme 52

HYDRAULIC PRESSURE SPECIFICATIONS

High At Idle In All Ranges

Main regulator valve sticking, EPC solenoid sticking. Check transmission wiring harness. Perform QUICK TEST under DIAGNOSIS & TESTING in FORD 4R70W ELECTRONIC CONTROLS article.

Low At Idle In All Ranges

Low fluid level, restricted inlet filter or damaged filter inlet seal, loose valve body bolts, damaged gaskets or separator plate, pump leakage, case leakage, faulty valve body, excessively low engine idle or main regulator valve sticking.

Low In "P"

Loose valve body, faulty main oil regulator valve sticking or reverse servo leakage.

Low In "R"

Separator plate, reverse clutch or reverse servo leakage. Loose valve body.

Low In "N"

Loose valve body or main oil regulator valve sticking.

Low In "OD"

Faulty forward clutch, main oil regulator valve or loose valve body.

Low In "2nd"

Forward clutch, intermediate clutch or valve body leakage.

Low In "1st"

Forward clutch, reverse servo or valve body leakage.

DIRECT CLUTCH PRESSURE TEST

Note. Shift quality is affected when pressure gauges are attached to transmission. DO NOT accelerate or decelerate rapidly during test. Transmission failure could result.

1. Attach a 300 psi (21.1 kg/cm 2 ) pressure gauge to the forward clutch pressure tap and the direct clutch pressure tap. (Scheme 52) Mount gauges inside vehicle.
2. Drive vehicle. Note pressure difference between forward clutch pressure reading and direct clutch pressure reading.
3. If the difference is less than 15 psi (1.05 kg/cm 2 ), direct clutch circuit is okay. If difference is greater than specification, there is a leak in direct clutch pressure circuit. Repair as necessary.

STALL SPEED TEST

Testing Precautions

When performing stall speed test, do not hold throttle open longer than 5 seconds. Allow a cooling period of 15 seconds with transmission in "N" position and engine speed at 1000 RPM between each test. If engine speed exceeds maximum limits shown, release accelerator immediately, as this is an indication of clutch or band slippage.

Testing Procedure

Ensure engine is at normal operating temperature. Apply parking and service brakes. Stall test transmission in each driving range at WOT. Note maximum RPM obtained. Engine speed should be within RPM specifications. See STALL SPEED SPECIFICATIONS table. If maximum RPM obtained is not within specifications, see STALL SPEED TEST RESULTS .

STALL SPEED SPECIFICATIONS

Low In All Ranges

Check engine performance. Check torque converter using bench test for stator one-way clutch slippage. See STATOR ONE-WAY CLUTCH CHECK .

High In "OD" Position

Check planetary one-way clutch.

High In "OD", "2" & "1" Position

Check forward clutch or intermediate clutch.

High In "D", "2", "1" & "R" Position

Perform HYDRAULIC PRESSURE TEST .

High In "R" Position

Check reverse clutch and reverse band or servo.

Test Procedures

1. A no-drive condition can exist even with correct transmission fluid pressure, because of inoperative clutches or bands. The inoperative components can be located by substituting air pressure for fluid pressure to determine location of malfunction.
2. Remove pan and drain fluid. Remove valve body assembly from transmission. See «VALVE BODY ASSEMBLY»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission__valve-body-assembly) in ON-VEHICLE SERVICE. Using attaching screws, install Transmission Test Plate (T92P-7006-A) and gasket. Tighten bolts to 80-97 INCH lbs. (9-11 N.m)
3. With a rubber-tipped air nozzle, apply air pressure into the appropriate test plate locations specified in the following tests. (Scheme 53) If servo or accumulator does not move when air is applied, clean and inspect to locate cause. If during test, 2 clutches apply or clutch fails to operate, check fluid passages in case and front pump for blockage or damage.

Scheme 53

Reverse Clutch

Apply air pressure to reverse clutch passage. A dull thud can be heard when clutch piston is applied, or movement can be felt by placing fingertips on clutch drum.

Forward Clutch

Apply air pressure to the forward clutch apply passage. A dull thud can be heard when clutch piston is applied, or movement can be felt by placing fingertips on input shell.

Intermediate Clutch

Apply air pressure to intermediate clutch apply passage. A dull thud can be heard or felt if clutch is operating properly.

Overdrive Servo

Apply air pressure to overdrive servo apply passage. Operation of the band is indicated by tightening of the band around reverse clutch drum. A thud can be felt on the servo cover when the servo returns to the release position as a result of spring force from the release spring. The band will then relax.

Reverse Servo

Apply air pressure to reverse servo apply passage. A dull thud can be heard when the reverse band tightens around the planetary assembly. Movement of the ring gear should also be detected.

Direct Clutch

Apply air pressure to direct clutch passage in the adapter plate. A dull thud can be heard or felt on the drive shaft if clutch is operating properly.

2-3 Accumulator

Apply air pressure to 2-3 accumulator passage. Accumulator piston should unseat and can be detected by inserting a metal rod into 2-3 accumulator piston hole. When piston unseats, rod will move.

1-2 Accumulator

Apply air pressure to 1-2 accumulator apply passage in the adapter plate. A dull thud can be heard or felt if accumulator is operating properly.

TORQUE CONVERTER

Note. Torque converter is a sealed unit and cannot be disassembled for service. Replace if found to be defective. The following tests will identify a defective converter.

Flushing

Whenever transmission has been disassembled to replace worn or damaged parts or because valve body sticks due to foreign material, converter and oil cooler must be cleaned using a mechanically operated agitating cleaner. Under NO conditions should converter or oil cooler be cleaned by hand agitation using solvent.

Leak Test

If torque converter welds indicate leakage, attach Rotunda Torque Converter Leak Detector (014-R1067) to converter and follow detector kit instructions.

End-Play Check

1. Insert Tester (T80L-7902-A) into converter pump drive hub until tool bottoms. Expand sleeve in turbine spline by tightening threaded inner post of tester until sleeve is securely locked into spline. (Scheme 54)
2. Attach a dial indicator to tool with button on dial indicator positioned on converter pump drive hub. Zero dial indicator. Lift tool upward as far as tool will go and note dial indicator reading.
3. Reading is total end play of turbine and stator. If end play exceeds specification, replace torque converter assembly. See «TORQUE CONVERTER END PLAY SPECIFICATIONS»(/ford/econoline/i-1985-2013/remont/automatic-trans/#overhaul-4r70w-automatic-transmission) table.

TORQUE CONVERTER END PLAY SPECIFICATIONS

Scheme 54

Stator One-Way Clutch Check

1. Insert one-way Clutch Holder (T77L-7902-R) into one of the grooves in the stator thrust washer. Insert Torque Adapter (T76L-7902-C) into converter impeller hub to engage one-way clutch inner race.
2. Attach a torque wrench to torque adapter. With clutch holder held stationary, turn torque wrench counterclockwise. (Scheme 55) Converter one-way clutch should lock-up and hold at 10 ft. lbs. (14 N.m). One-way clutch should rotate freely in a clockwise direction.
3. Repeat lock-up test in at least 5 different locations around torque converter. If clutch fails to lock-up and hold, replace torque converter.

Scheme 55

Stator-To-Impeller Interference Check

1. Position pump support shaft on bench with splined end pointing up. Mount torque converter vertically onto shaft so pump support shaft splines engage one-way clutch splines. (Scheme 56)
2. While holding pump support shaft stationary, rotate torque converter counterclockwise. Torque converter should rotate freely without interference or scraping within assembly. Should interference or a scraping sound from within torque converter or if converter does not rotate freely, replace converter unit.

Scheme 56

Scheme 57

1. Place torque converter on bench, front side down. Install pump support to engage mating splines of pump support shaft.
2. Install forward clutch assembly and input shaft, engaging the splines with turbine hub. While holding stator shaft stationary, rotate turbine with forward clutch assembly and input shaft. (Scheme 57)
3. Turbine should rotate freely in both directions without interference or noise. Torque required to turn shaft should not exceed 84 INCH lbs. (9.5 N.m) If interference or noise exists, stator front thrust washer may be worn and torque converter should be replaced.
