P0745

Pressure Control Solenoid A

Q: Is it safe to drive with P0745?

Short trips are usually fine, but slipping or harsh shifts and limp mode can accelerate transmission wear, so repair it soon.

Q: Can I just clear P0745?

You can, but if the solenoid, fluid, or wiring is at fault it will return — often quickly under load.

What it means

P0745 means the transmission's pressure control solenoid A — the valve that regulates hydraulic line pressure for shifting — is not responding correctly. Wrong line pressure leads to harsh, slipping, or delayed shifts, and the transmission may enter a protective limp mode. It is often caused by low or dirty fluid or a wiring fault, not just the solenoid itself.

Can I keep driving? Usually drivable, but expect harsh or slipping shifts and possible limp mode — get it looked at soon to avoid transmission wear.

Common symptoms

What you'll notice

Harsh, delayed, or erratic gear shifts
Transmission slips or fails to engage cleanly
Transmission may drop into limp (failsafe) mode
Check-engine light on
Reduced fuel economy

Common causes

Most likely first

Failed pressure control (line pressure) solenoid ALikely
Low or contaminated transmission fluidCommon
Damaged wiring or corroded connectors in the solenoid circuitCommon
Restricted valve body or internal hydraulic faultLess often
Failed transmission control module (TCM)Less often

How to diagnose & fix

Work through it in order

Check transmission fluid level and condition first; top up or service if low, dirty, or burnt.
Read freeze-frame data and inspect the solenoid connector and wiring for damage or corrosion.
Measure the solenoid's resistance against spec and test its circuit; replace the solenoid if out of range.
If wiring and solenoid check out, inspect the valve body for sticking or debris.
Clear the code and road-test; suspect the TCM only after the above pass.
