On the 2014-2020 Acura MDX 3.5L J35Y5 V6, third-generation MDX models with the ZF 9-speed automatic suffer from torque converter shudder during light throttle acceleration between 30-50 mph. The lockup clutch in the torque converter vibrates as it engages, creating a sensation similar to driving over rumble strips that many owners mistake for an engine misfire.

This issue also affects: Acura TL, Mitsubishi Outlander, Acura ILX

Common Symptoms

Vibration/shudder at 30-50 mph under light throttle
Sensation like driving over rumble strips
Shudder disappears under hard acceleration
Vibration felt through seat and steering wheel
Transmission slipping sensation

How to Fix

Update the TCM software to the latest Acura calibration that modifies torque converter lockup strategy. Perform a complete ATF drain and refill with Honda DW-1. If shudder persists after software update and fluid change, the torque converter assembly must be replaced.

TipGet the TCM update first — it resolves about 70% of cases for free under warranty. If the shudder returns after 10,000 miles, the torque converter needs replacement. Do not let the dealer just change fluid and send you home.
