2007 DODGE RAIDER

Typical onset: 90,000-140,000 mi

Symptoms: Harsh 2-3 or 3-4 shifts with shuddering under light throttle, Slipping in overdrive, especially when towing or loaded, Check engine light with P0750, P0731, or solenoid pack codes, Delayed engagement from Park to Drive after sitting overnight

Fix: The 45RFE/545RFE transmission is undersized for the 4.7L V8's torque, particularly in hot climates. Solenoid pack failure is common (8-10 hours R&R), but by the time codes appear, clutch pack damage often requires full rebuild. Expect 18-22 hours labor for rebuild, add 4-6 hours if torque converter is also cooked. Preventive fluid changes every 30k mi can delay but not prevent failure.

Estimated cost: $2,800-4,500

Typical onset: 70,000-110,000 mi

Symptoms: Grinding or growling noise in all gears that increases with speed, Noise present in neutral with clutch out (manual) or in drive coasting, Metal shavings in transmission fluid during service, Vibration felt through shifter at highway speeds

Fix: Output shaft bearing wears prematurely due to inadequate lubrication design and heat buildup. Requires transmission removal to replace bearing and often the output shaft itself if splines are damaged. 14-18 hours labor including fluid refill and alignment check. Catch it early before bearing disintegrates and contaminates the entire transmission.

Estimated cost: $1,800-2,600

Typical onset: 60,000-100,000 mi

Symptoms: Trans fluid puddle under front of vehicle near radiator, Pink or red fluid mixed with coolant in overflow tank, Transmission overheating warning or erratic shifting after coolant contamination, Milky brown fluid on transmission dipstick

Fix: Steel cooler lines rust through at mounting brackets and where they enter the radiator-mounted cooler. If coolant mixes with ATF, immediate flush of both systems required plus radiator replacement. Lines alone are 3-4 hours; if internal radiator cooler fails, add radiator R&R (6-8 hours total) plus transmission fluid flush cycles. Many shops install external aftermarket cooler to prevent recurrence.

Estimated cost: $800-2,200

Typical onset: 80,000-130,000 mi

Symptoms: Random no-start with no crank, shifter won't move out of Park, Limp mode with transmission stuck in 2nd or 3rd gear, Multiple solenoid codes (P0750, P0755, P0760) appearing simultaneously, Speedometer drops to zero intermittently while driving

Fix: TCM mounted on transmission valve body fails from heat cycling and vibration. Requires transmission pan removal, valve body drop, and TCM replacement with VIN programming. 4-6 hours labor. Some units can be repaired by specialists for half the cost of new, but core exchange requires 2-3 week turnaround. Common to also replace output speed sensor during this job as they fail concurrently.

Estimated cost: $900-1,600

Symptoms: Rough idle and stumbling acceleration after refueling, Loss of power on highway grades, won't maintain speed above 65 mph, Engine stalling at idle after extended driving, P0171, P0174 lean codes with no vacuum leaks found

Fix: In markets with questionable fuel quality, the in-tank filter clogs with sediment and water contamination. Tank must be dropped for filter replacement as it's integrated with the fuel pump assembly. 3-4 hours labor. Many techs replace the entire pump module ($400-600 part) rather than risk old pump failure after disturbing it. Use premium fuel and add fuel system cleaner every 5k mi in high-sulfur regions.

Estimated cost: $600-1,000

Typical onset: 70,000-120,000 mi

Symptoms: No crank in Park, but starts in Neutral or vice versa, Backup lights don't work or stay on in all gears, Cruise control won't engage or disengages randomly, P0705, P0708 transmission range sensor codes

Fix: Range sensor (neutral safety switch) on driver's side of transmission wears from heat and contamination. Requires shifter linkage adjustment after replacement to ensure proper gate alignment. 2-3 hours labor including alignment procedure and test drive through all gear positions. Often replaced during transmission service as preventive measure.

Estimated cost: $350-550
