GENERAL INFORMATION

Zachekanka of a case of hydrokinetic transfer at installation of a sealing ring


And – a core for a zachekanka,
In – traces of factory stamping,
With – points of stamping of a new sealing ring

Since May, 1986 the sealing ring of the oil pump is recorded by a zachekanka of a case of hydrokinetic transfer.

Knot of the vacuum regulator of gear shifting

1 – vacuum regulator,
2 – pusher,
3 – valve,
4 – identification pro-point of the valve
Since June, 1988 the new valve of the vacuum regulator of gear shifting with designation is used: 84 GT 7D 080 BA. It can be determined by a pro-point in a middle part (4).

Bolts of adjustment of tapes of brakes of the automatic transmission

And – a bolt of adjustment of a tape of an average brake,

In – a bolt of adjustment of a tape of a forward brake

Since August, 1988 the method of adjustment of tapes of brakes of the automatic transmission is changed:
  – the bolt (A) of adjustment of a tape of an average brake has to be unscrewed (after full screwing up) on 2,5 turns;
  – the bolt (V) of adjustment of a tape of a forward brake has to be unscrewed (after full screwing up) on 2 turns.

The changed form of the oil pallet of the automatic transmission

The arrow specified the changed pallet form.

From model of 1989 automatic transmissions are equipped with oil pallets of the changed form and oil pumps with longer oil receiver.

From a factory code 8 K 24 automatic transmissions have oil pallets with a magnet.

AUTOMATIC FORD A 4 LD TRANSMISSION

In April, 1989 the electrohydraulic control of the transmission about blocking of hydrokinetic transfer is entered by system of inclusion of the 3rd and 4th transfers.

Blocking of coupling of hydrokinetic transfer provides the electronic EEC IV actuation device. This coupling will be unblocked by each pressing a brake pedal.

Transition from the 3rd to the 4th transfer provides the additional electromagnetic valve operated by the electronic EEC IV actuation device.

The switching moment with the 4th on 3-y transfer (a transfer reduction) is optimized on the basis of data on the speed of the movement, load of the engine and provisions of a pedal of an accelerator.

After pressing of a pedal of an accelerator against the stop (kick-down) the electronic device operating automatic transfer causes:

  – blocking of hydrokinetic transfer to time of the movement on the 3rd transfer with a speed of 130 km/h;
  – switching of transfer with the 3rd on the 4th at speed more than 6100 rpm;
  – a transfer reduction with the 4th on 3-y at engine speed less than 4200 rpm.

Adjustment of a cable of a reduction of transfers (kick-down mechanism)

PERFORMANCE ORDER
1. To include ignition, to press against the stop a pedal of an accelerator and to hold it in this situation.
2. To turn the lever of the kick-down mechanism of the automatic transmission counterclockwise against the stop.
3. To install Ford 17.031 adaptation on a cable not to allow its excessive tension.
4. To weaken bolts of fastening of the electromagnetic valve.
5. To move the electromagnetic valve in forward situation at which considerable resistance is felt.
Prevention

If the electromagnetic valve is moved too far, the cable will be weakened. In this case it is necessary to remove the valve back and to repeat the previous operations.


6. To tighten the corresponding moment at first the lower bolt of fastening, and then the top bolt.
7. If adjustment is carried out correctly, then the electromagnetic valve has to hold the kick-down mechanism lever at distance of 0,3-0,8 mm clockwise from extreme situation.
8. If the cable is too tense, then the electromagnetic valve will not reach the correct situation and the lever after passing through a magnet will return to the previous situation. It is necessary to repeat adjustment of a tension of a cable.

Other information concerning a technical characteristic of adjustment and repair of the automatic transmission is provided in subsection 6.3 (Ford C3 transmission) and in subsection 3.1.3.15 (Ford A 4 LD transmission).
