Chrysler 300 FAQ

Common Chrysler 300 Transmission Questions

On a 2005–2010 300 with 545RFE, P0745 governor solenoid is the most common cause. $350–550 repair.

Identical. Same platform, same transmission, same failure patterns and repair costs.

If you're seeing P0740, P0750, P0755 together on a W5A580, yes — conductor plate failure. One repair, not multiple solenoids.

3–4 days.

The 300 Hemi is a well-built sedan — transmission rebuild is worth it for a clean car.
