Don't see your model? We service all Dodge vehicles — call us to confirm.
Dodge builds vehicles with a singular focus: performance. The Charger and Challenger are the last remaining American muscle cars with V8 power, and the Durango is one of the few three-row SUVs available with a genuine HEMI V8. These are vehicles built for drivers who want excitement, and they deserve service from a shop that appreciates what makes them special. Riley Auto Care & Transmissions services the complete Dodge lineup with the expertise these performance vehicles require.
Dodge's HEMI V8 engines — the 5.7L, 6.2L Hellcat, and 6.4L 392 — are powerful, durable powerplants that reward proper maintenance. The Multi-Displacement System (MDS) on the 5.7L HEMI can develop lifter issues similar to GM's AFM system, and we can diagnose and address these failures. For Hellcat and Redeye owners, we pay particular attention to supercharger belt condition, intercooler coolant, and oil quality — all critical for maintaining extreme power output.
As HP Tuners certified technicians, we can recalibrate Dodge's PCM for improved performance, whether you're looking for more power from a stock engine or optimizing a modified setup. The 8HP70 ZF automatic transmission found in Chargers and Challengers is a robust unit that benefits from regular fluid service. Serving Dodge owners throughout the area, we deliver the performance-focused expertise your vehicle deserves.
Riley Auto Care & Transmissions is HP Tuners certified. We can unlock the full potential of your Dodge with professional ECU tuning — improving power, fuel economy, and drivability.
