What fuse powers the transmission control circuit in this diagram?

Fuse position 24, a 15A fuse in the fuse box, which feeds the Main Relay via B/R and B/W wires.

What wire colors run from the Transmission Control Module to the shift solenoids?

G/R, G/Y, and G wires run from TCM connector E43 pins 11, 12, and 13 through connectors E55/C11 and C08/P01 to the shift solenoid valves and TCC solenoid valve at connector P04.

Where are the vehicle speed sensors connected?

One vehicle speed sensor is on the transmission at connector P06 (W and O wires from TCM pins 2 and 3 via E55/C11 and C08/P01), and a second vehicle speed sensor is in the combination meter, connected through E37/G06 pin 22 (Y wire) and G09/G11, with B/Y wires to ground point 10.

Which connector pins does the Engine Control Module use in this circuit?

The ECM connects at E34 pin 10 and at E33 pins 10, 16, and 7, with P/Bl and P/G wires linking to the cruise control unit and the transmission control module.

What solenoids does the TCM control according to this diagram?

The TCM controls the shift solenoid valves and the TCC (torque converter clutch) solenoid valve, connected at P04 pins 1, 2, and 3, each internally grounded.

This document is a scanned automotive wiring diagram covering the automatic transmission control circuit. Power flows from fuse position 24 (15A) in the fuse box through wires B/R and B/W to the Main Relay (connector E61, pins 1-4), then via Bl and Bl/B wires to the Engine Control Module (connectors E34 pin 10 and E33 pins 10, 16, 7) and the Cruise Control Unit. The Transmission Control Module (A/T) connects at E43 (pins 26, 6, 1, 16 on top; pins 2, 3, 4, 11, 12, 13 on the bottom) using wire colors W, O, G/R, G/Y, and G. Circuits pass through intermediate connectors E55/C11 (pins 6, 12, 2, 18, 17, 6) and C08/P01 (pins 5, 4, 6, 9, 8, 7) to the Vehicle Speed Sensor (Transmission) at connector P06 and to the Shift Solenoid Valves & TCC Solenoid Valve at connector P04 (pins 1, 2, 3), each solenoid grounded. A second Vehicle Speed Sensor located in the combination meter connects via E37/G06 pin 22 (Y wire) and G09/G11 with B/Y wires to ground point 10. The diagram gives complete pin numbers and wire color codes for diagnosing the A/T control system.
