    One very significant change that took place in our industry occurred when manufacturers chose to place the TCM inside the transmission. By minimizing the amount of wires going to the transmission, it saved them a considerable amount of money. However, for us in the repair and rebuild industry, this can be frustrating from both a diagnostic and cost standpoint, especially when the solenoids are integral to the TCM. And/or when programming is essential to complete the repair correctly and efficiently.

  • Shift Pointers: 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.

    It’s always unsettling when a transmission comes back after the customer has had it for only an hour; especially when it came back on a hook. Such was the case at a local transmission shop with a 42RE transmission.

    A 2008 Honda Accord using the B97A transmission behind a 3.5L engine was brought to Newmarket Transmissions from a general repair shop to be rebuilt. They had changed the radiator and when topping off fluids, they noticed the “strawberry milkshake” condition of the transmission fluid. The radiator was also contaminated with the milkshake condition.

    I came to know Mario Aristides, a veteran of the transmission industry, when I began working with ATSG in 1990. A good friend of Robert Cherrnay, he had specialized in European transmissions. He provided technical assistance to ATSG with his knowledge regarding transmissions found in Mercedes vehicles throughout the ’90s and into the following decade. Well into his 70s, he is still very much active in the industry with European vehicles. Every now and again we get a call from him where he informs us of a problem he has encountered with his famous line, “You must make an issue with this!” And such is the reason for this article.

    After vehicle tossed from one shop to another, TCM replaced and vehicle returned to owner.

    The idiom “hot potato” is not new to many folks, and in fact many have been participants of a hot potato scenario of one kind or another. Here is one that began with an engine replacement and ended with needing a TCM (Transmission Control Module).

  • Shift Pointers: Another Case of Brutality

    Many years ago I wrote an article titled “Brutality.” The article was about Toyota’s severe 2-3 shift issues with their U140/U150 series transmission. At that time the most common reason for this dilemma was a defective PCM.

    Anthony Nuzzo, the owner of Accord Transmission & Differential, originally gave us a call on a 2003 Saab 9-3 2.0L Turbo, using the AW50-40LE transmission that was experiencing a harsh engagement into reverse when hot. His tech Pete Morreale was out on vacation so Anthony was handling the diagnostics, making him quite a busy man.

    A 2006 Mazda 3 with a 2.3L engine using a front-wheel-drive five-speed automatic transmission (FS5A-EL known as the FNR5 in Ford) comes into Bebes Transmitech shop in Puerto Rico. The A/T warning lamp is illuminated so codes were immediately checked. Only P0791 was stored in memory. It was logged and cleared before going on a road test where the code set immediately after take off.
