Ford Escape: 6F35 Automatic Transmission Torque Converter Clutch Shudder

The 6F35 six-speed SelectShift automatic transmission fitted to most Escape variants exhibits a well-documented torque converter clutch (TCC) shudder at light throttle cruise speeds between 50-100 km/h. Ford issued TSB 18-0244 addressing TCC shudder on multiple EcoBoost applications, recommending a Mercon LV fluid drain-and-fill as a first step. However, in cases where the friction material in the torque converter is already glazed, fluid alone does not resolve the issue and a torque converter replacement is required. The shudder is often misdiagnosed as an engine misfire.

• Rhythmic shudder or buzz felt through the floor at 50-100 km/h under light constant throttle
• Vibration disappears immediately when accelerating or coasting, but returns at cruise
• Sensation similar to driving over rumble strips at a constant speed
• DTC P0741 or P175F stored in the TCM
• Shudder worsens when transmission fluid is old or contaminated

1. 1

   Test drive at 80-100 km/h at light, steady throttle on a flat road.

2. 2

   Feel for a rhythmic vibration or buzz through the floor and seat that disappears when you lightly accelerate or lightly brake.

3. 3

   Check transmission fluid colour (should be red/pink, not brown or burnt-smelling).

4. 4

   Ask for service history showing Mercon LV fluid changes.

5. 5

   Check for stored DTC P0741 (TCC performance) or P175F.

$250 to $3,200 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the transmission fluid ever been changed, and was Mercon LV specified fluid used?”
• “Do you notice any vibration or buzzing sensation through the floor when cruising at motorway speed with light throttle?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
