Short answer: Harsh Comfort-mode shifts are a common MDX Type S complaint. Start with software and a careful fluid inspection before assuming you need a full transmission.
Symptom: Jerky or harsh upshifts/downshifts in Comfort, smoother in Sport, occasional flare or clunk, or owner worry about a Type S transmission defect.
What to check first
- Compare Comfort vs Sport on the same road.
- Ask for the latest TCM/PCM software.
- Record a video of the harsh shift for the service advisor.
- Have fluid inspected if the problem is getting worse.
Likely causes
- Transmission calibration in Comfort mode. Owners say Comfort mode feels notchy or jerky while Sport is smoother. Software updates are the first dealer step.
- Aggressive downshifts / torque management. Some describe a brief neutral-like flare or harsh re-engagement during certain throttle inputs.
- Actual transmission or transfer-case wear. If harsh shifts come with noise, flares, or metal in fluid, dig deeper than a software flash.
What it usually costs
Software updates are usually covered. Fluid service is moderate. A full transmission is major.
Is it safe to keep driving?
Drivable if mild. If it flares into neutral or bangs hard, limit driving and get it diagnosed.
