A/T SHIFT LOCK SYSTEM
DescriptionINFOID:0000000001327387
 The mechanical key interlock mechanism also operates as a shift lock:With the ignition switch turned to ON, the selector le ver cannot be shifted from “P” position to any other posi-
tion unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless the selector lever is placed in “P” position.
 The shift lock and key interlock mechanisms are contro lled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.

7. Push A/T assembly harness connector.CAUTION:
Be careful not to damage connector.
8. Remove bracket (1) (VK45DE), clips (2), oil pan (3) and oil pan gasket.
 : Vehicle front
 : Bolt (22)
 Drain plug (4)
9. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
 If frictional material is de tected, perform A/T fluid cooler
cleaning. Refer to AT-13, "
A/T Fluid Cooler Cleaning".
10. Remove magnets from oil pan.
