P0762: Shift Solenoid C Stuck On

A shift solenoid is an electrically switched valve in the valve body; the module checks whether its clutch follows the command by gear ratio, shift time or a pressure switch. P0762 means solenoid C is commanded off but its clutch stays applied. GM's Honda-built five-speed flags a 2–3 shift slower than 0.8 s together with a 4–5 shift faster than 0.8 s, after two trips; the Allison 1000 a pressure switch 3 still applied after 2 s (up to 4 s when cold), after one trip. Ford calls it 'functionally failed on' – the CB26 brake does not release, which ties up the transmission when leaving second or sixth gear. Ford's 10R80 bulletins list it with a leaking clutch cylinder.

Medium severity. Can I keep driving?Drive as little as possible and gently. If the transmission slips or stays in one gear, go slowly to a repair shop or call for a tow truck.

Symptoms

Tie-up or jolt on shifts
Delayed shifts, engine revs high
Limp mode
Check engine light

Most likely causes

Shift spool or proportional valve sticking in the applied position
Clutch not releasing (stuck or burnt)
Solenoid stuck open or leaking
Control wire shorted to ground (permanently powered)

What to check, in order

Start with the simplest. You can tick off each step.

Check the fluid level and condition according to the manufacturer
Use the scanner to command the movement and compare the actual position with the requested one.
Check the transmission connector
Read the data with a transmission-compatible scanner
Measure the solenoid valve circuit
Leave opening the transmission to a specialized repair shop

Good to know

Repair difficulty: hard
It can trigger limp mode.
It affects emissions.
