No Shim and a Short

Lorenzo Ortiz from Phillips Transmission had a 2005 Acura TSX with the MCTA five-speed transmission come into his shop for repairs. After it was repaired and installed into the vehicle, it had a new problem. The car would not start. The immobilizer lamp was flashing and the scan tool could not communicate with the engine control module, yet all other modules would communicate.

Acura MDX with a Mind of its Own

Little did the owner of a 2005 Acura MDX know that at the time the transmission in his vehicle was being repaired that it was the start of a long uphill battle. The vehicle initially was towed into a shop for inspection due to a no-movement condition. In addition, the check-engine light was on indicating the presence of trouble codes, several of which were verified on a scanner.

It’s Not in the Manual

A while back one of our members called the tech line about a 2002 Toyota Sequoia that required replacement of the valve body. After the valve body was installed the vehicle had no reverse, pulled forward in neutral but drove perfectly when the selector lever was in the overdrive position.

Upgrading the Honda Impeller-to-Stator Bearing

Torque-converter rebuilders have been reporting Honda bearing failures in increasing numbers. The bearing failures have been from different locations within the converters and have been reported in most of the Honda and Acura models. The most common of the failures has been the bearing between the impeller and stator in the larger-diameter converters. In all converters, the bearing in this location carries most of the thrust load when the vehicle is accelerating, and it is typically the first bearing to fail. Because the larger-diameter converters are used in the larger, higher-torque V-6 applications, the thrust loads on this bearing are even greater.

Which Came First, the Chicken or the Egg?

Codes setting codes is not a new concept in the automotive industry. An example of this in the world of transmissions occurs in Dodge vehicles using the 41TE transaxle. If it develops a gear-ratio-error code such as P0731/2/3/4, code 1790 “Fault Immediately After Shift” can also be present as a result of the gear-ratio code or codes. In fact, the explanation given by the manufacturer for setting this code is: This code is set if the associated speed ratio code is stored within 1.3 seconds after a shift.
