P0893 Code: Multiple Gears Engaged

The P0893 code means the transmission computer detected a gear ratio that matches two gears being applied at the same time. This is a serious fault and the transmission can lock up. Do not keep driving the vehicle, and have it inspected right away.

What the P0893 code means

When two clutches or brakes that should never be applied together engage at once, the transmission fights against itself. The vehicle loses power suddenly or the drivetrain locks up. The computer notices it from the ratio between input and output speeds and stores the P0893 code.

The usual causes are a solenoid stuck on, a stuck valve in the valve body or an internal failure. On any transmission code, the first check is the fluid. Check the level using the manufacturer procedure, which often means the engine running and the fluid at a specific temperature. The fluid should be red or pink and should not smell burnt. Low or degraded fluid causes slipping, harsh shifts and solenoid or ratio codes that disappear once it is corrected.

Read up on the P0700 code as well, since it explains how transmission codes are read and why you need a scan tool that can talk to the transmission module, not just the engine computer.

P0893 code symptoms

  • The vehicle suddenly slows down or loses power.
  • Hard jolts or bangs when shifting.
  • Limp mode.

Likely causes of the P0893 code

  1. Solenoid stuck on. It applies a clutch that should be released.
  2. Stuck valve in the valve body. It sends pressure to the wrong clutch.
  3. Badly degraded fluid. Particles clog the valves.
  4. Internal failure. A damaged clutch or piston.

How to diagnose the P0893 code step by step

  1. Check the fluid level, color and smell.
  2. Read every transmission code with a scan tool that can access the transmission module.
  3. Inspect the solenoids and the valve body.

How to fix the P0893 code

  • Replace the solenoid or the valve body.
  • Repair the transmission if there is internal damage.

Technical reference data

  • The measured ratio does not match any valid gear.
  • Approximate values only: check the manufacturer data for your vehicle.

Brand-specific notes

This code shows up on a couple of well-known transmission families. If you drive one of them, mention it to the shop so they can look at the known weak spots first.

P0893 on Chrysler

It appears on Chrysler 62TE transmissions.

P0893 on GM

It appears on GM 6T transmissions.

Frequently asked questions about P0893

Can I drive with a P0893 code?
It is not recommended. The transmission can lock up, which can leave you stranded and may be dangerous in traffic.
Is the P0893 code serious?
Yes. Two gears applied at once puts heavy stress on the internal parts and can destroy the transmission if you keep driving.
What usually fails?
A solenoid or the valve body. If neither is at fault, the cause is internal damage to a clutch or a piston.
How much does it cost to fix P0893?
Between $300 and $4,000. A solenoid or valve body repair sits at the low end, and an internal rebuild at the high end.
What does the P0893 code mean?
The P0893 code is a generic OBD2 code that means the transmission computer sees a ratio that matches two gears being engaged at the same time.
Will a P0893 code clear itself?
The light may go out if the fault does not return, but a stuck solenoid or valve will bring it back. Do not wait for it to clear before you have the transmission checked.
What is the most common cause of P0893?
A solenoid stuck on or a valve stuck in the valve body, often helped along by degraded fluid.
