Why is my Dodge Avenger stuck in 2nd gear (limp mode)?

Short answer: When the Avenger's transmission computer sees a problem, it goes into limp mode: it locks the transmission in one gear (usually 2nd) to protect it. P0700 just means 'the transmission has a code stored'; you need a scan tool that reads the transmission computer to see the real code. Owners found solenoids, wiring and the TIPM (the main fuse and relay box) involved. Parts-swapping without the real code wastes money.

Symptom: The car suddenly feels like it's in neutral, then won't shift above 2nd. The check engine light is on. Restarting may clear it for a while.

What to check first

1. Get the transmission codes read with a scanner that talks to the transmission computer, not just a basic code reader.
2. Check the fluid level and condition.
3. Check the wiring connectors at the transmission for damage or corrosion.
4. Check for software updates at a dealer.

Likely causes

1. Shift solenoid pack. One owner had it replaced twice.
2. Wiring or connector short. A tech fixed the same code on another Chrysler by fixing a shorted harness.
3. TIPM or computer. Replaced on one car; not the fix by itself.
4. Speed sensors. Another owner replaced both without fixing it.

What it usually costs

The threads didn't give dollar amounts. One owner's car got a computer flash, a solenoid twice and a TIPM, and was eventually bought back. Another replaced both speed sensors, the TCM, a solenoid and fluid and filter and still had codes. Get the real code before buying parts.

Is it safe to keep driving?

You can usually limp home or to a shop, but stuck in 2nd you can't keep up with highway traffic, and a car that drops to neutral is dangerous in traffic. Verify with a mechanic.

DIY or shop?

DIY for fluid checks and reading codes with a capable scanner. Diagnosis and repairs are mostly shop work.

What owners report

• In Transmission issues on DodgeForum, a 2008 SE owner's car slipped to neutral, then went into limp mode in 2nd with P0700 and P0755. The dealer flashed the computer, replaced the solenoid twice and the TIPM, and the car was eventually bought back. A tech replied that he fixed the same code on a 300M by finding a shorted wiring harness.
• In Trans limp mode on DodgeForum, a 2008 owner had replaced both speed sensors, the TCM, a solenoid, and the fluid and filter and still had P0700 and P0750. Members said he needed a scan tool that reads the transmission computer to find the actual cause.

Quick tip

Don't let anyone start swapping parts on a P0700 alone. Get the real transmission code and have the wiring checked; both threads show how expensive guessing gets.

Vehicle focus: 2008–2014 Dodge Avenger and Chrysler Sebring/200 with the 4-speed or 6-speed automatic.

Safety / mechanic note

Dropping to neutral or being stuck in 2nd can be dangerous in traffic. Verify with a mechanic.
