Why is my Chrysler Concorde transmission slipping or slow to go into reverse?

Short answer: Concorde automatics are fussy about fluid: members stressed using only Chrysler ATF+4, since a substitute fluid can cause hard shifts, shudder and slipping. If the rpm suddenly surges at cruise, get the transmission codes read (solenoid or torque converter codes are common). A delay going into reverse on cold mornings in a high-mileage car usually means internal seals are wearing out.

Symptom: At steady speed the rpm jumps from about 2,000 to 5,000, or on cold mornings it takes a while to engage Reverse.

What to check first

1. Find out what fluid is in it. Members said only ATF+4 belongs in these transmissions.
2. Read the transmission codes. Codes for the 2-4 solenoid or the torque converter clutch point the diagnosis.
3. Have the solenoids and wiring tested before agreeing to a rebuild.
4. Check the fluid level and condition.
5. For delayed reverse only when cold, weigh the car's age and mileage against the cost of an overhaul.

Likely causes

1. Wrong transmission fluid. A non-ATF+4 fluid can cause shudder and slipping.
2. Solenoid or torque converter clutch fault. Shows up as stored transmission codes.
3. Worn internal clutch piston seals. Causes delayed engagement on cold starts in high-mileage cars.

What it usually costs

One 1997 Concorde owner with 87,000 miles was quoted $2,000 for a transmission rebuild; a member suggested shopping for a cheaper local rebuild. Prices from owner posts.

Is it safe to keep driving?

A transmission that slips or surges at speed can leave you without power. A short delay engaging reverse is more an annoyance, but it will get worse. Verify with a mechanic.

Recalls, bulletins and complaints in plain words

• Recalls: NHTSA lists no recall for transmission slipping on the Chrysler Concorde in the model years we could check on 2026-10-24 (the recall lookup returned an error for 1 model-year queries). Check your VIN at nhtsa.gov/recalls. If your car is part of a recall, the dealer fixes it for free.
• NHTSA complaints: 305 keyword-matched complaints for Chrysler Concorde 1993–2004 (of 2,293 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-24; keywords: transmission, slip, shift, gear, reverse, torque converter). This counts complaints that mention these words. It is not a defect finding.

What owners report

• In Torque converter slipping on 97 chrys. Concord lk on Car Talk, a 1997 Concorde 3.5 with 87,000 miles had the rpm surge from about 2,000 to 5,000 at 35 mph and was quoted $2,000 for a rebuild. Codes showed a 2-4 solenoid circuit error and a torque converter clutch fault, while the solenoids measured within spec. Members stressed using only genuine ATF+4, warning that substitute fluids cause hard shifts and shuddering, and suggested shopping for a local rebuild if the car is otherwise good.
• In 2001 Chrysler Concorde transmission on Car Talk, a 2001 Concorde with 387,000 miles and fluid changes every 30,000 miles sometimes wouldn't go into reverse right after a cold start. A transmission specialist said it was age: the clutch piston seals were leaking, an overhaul was the only fix, and he'd just ride it out.

Quick tip

Fluid first. If anyone has topped it off with generic ATF, get it changed to ATF+4 and read the codes before you pay for a rebuild.
