What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Have actual idle speed, engine running quality and mount condition and installation assessed before further transmission work. Use the correct specifications instead of raising idle to mask the complaint.

2CarPros editorial correction - October 12, 2026

The earlier suggestion to increase idle speed in Drive or use Neutral as a repair has been withdrawn. Have the vibration diagnosed, including actual idle speed, engine running quality and the condition and installation of the mounts, using the correct vehicle specifications. Do not adjust idle controls to mask an unidentified fault. Another owner's similar symptom does not establish the cause, and no successful repair was reported for the original Mazda.
