2. Fit the blanking plug to the cylinder block access aperture.
9. Secure the oil cooler pipes.
Fit new Dowty washers to each union. Connect the upper
and lower cooler pipes.
Tighten to the specified torque figure.

Dual-Linear Switch (DLS)
The TCM detects gear selection by means of a switch fitted to the 'J' gate; the DLS contains two multi-track slider switches,
of which the upper controls P R N D and the lower 4 3 2 .
Output from the DLS is changed as the select or lever is moved, thus indicating selected gear position. The parallel signal is
input to the TCM by 4 discrete logic wires W0, W1, W2 and W3. The particular sequence, or gray code, will indicate which
shift position is selected, as shown in the following table where 0 = low and 1 = high:
