Honda 5-Speed

TCC Shudder or Moan

An engine vibration during lockup apply may be mistaken for a TCC apply shudder on some 2005-06 Honda Odyssey models with Active Control Engine Mounts (electronic). Check to verify that the rear engine mount has not failed. There must be a minimum clearance of 0.024" (0.610mm) between the rear engine mount's rubber bumper and the mount bracket.

There should be no visible distortion (bulges) seen on the rubber mount. An example of a rear engine mount that is in good condition shown below.

Technical Bulletin #1582

Transmission: 4F27E, FN4A-EL, FNR5 & FS5A-EL Subject: P0771, P0741/Stator Bushings

Application: Ford & Mazda Issue Date: January, 2014

4F27E, FN4A-EL, FNR5 & FS5A-EL

P0771, P0741/Stator Bushings

Codes P0771 Shift Solenoid E Mechanical (Stuck Off) and P0741 TCC Solenoid Circuit (Stuck Off) can be very misleading. Some people go straight to the solenoid and replace it. Then have the same code come back after long drive.

What we need to do is look at freeze frame data and look at the TCC slip rate when code set. Clear codes and drive while watching the tcc slip rate when commanded on. It will take more than one TCC slip per ignition cycle to set codes. Once we see TCC slip rate is changing when commanded then we know for the most part solenoid is ok, and the lock-up valve moved.

One area of concern is the stator bushing seen in figure 1. They wear out and cause a leak in the TCC circuit and will cause these codes. The bushings are the seals in this circuit.
