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.

Nissan RE5R05A: Converter shudder after repair of a radiator cooler failure
This vehicle is a 108,261-mile 2000 Nissan Pathfinder with pink ATF. Sound familiar? Yep, the radiator had failed. We had ATF in the radiator and anti-freeze in the ATF – typical Nissan repair these days. Seems like 20 years ago we had the same issues.
4T65-E Valve-Body and Channel-Plate Identification
Let’s start with the valve body. Unfortunately, there are no casting numbers on the 4T65-E valve body for quick identification. The four most-common 4T65-E valve bodies are the early GM, late GM, early Volvo and late Volvo. There are more than four variations, and they can be found during the crossover years of 2002 and 2003. There are four questions that you need to answer to properly identify the valve body.
Turn It Around
The show was called “The Turnaround King.” It was about a consultant who is called in when a business is in pretty deep trouble and in imminent danger of failing. His job is to analyze the business in its current state and see whether he can teach the owners how to turn it around to save its life.
Hot off the Wire
My first appointment of the day was a customer with a 2001 PT Cruiser. The complaint was, “It feels like the gears are all slipping, and a light is on in the gauge panel.”
I started my evaluation with a fluid check and pulled the codes. The fluid was at normal level, and the code pulled up was P0750 for a solenoid error in the TCM. There were no ECM codes.
Solenoid-Pack Information for the Chrysler 62TE
The 62TE solenoid pack is made up of six shift solenoids, one line-pressure solenoid, a temperature sensor and five pressure switches. The pressure switches are just like the ones in a 604 solenoid pack.
Overheated Honda Converters/740 Codes
Overheated Honda converters have become a living nightmare for many transmission and torque-converter shops, one that has lingered way too long because of the many misconceptions and missteps during the problem-solving process. The blame game has gone back and forth, but the torque-converter rebuilders have been receiving most of the criticism.
Volkswagen DSG 02E: A simple fix for a solenoid problem
With the increase in manufacturers forcing the purchase of subcomponent replacements rather than enabling you to buy only what you need, it’s great to get a break every once in a while. Such is the case with Volkswagen’s 02E Direct Shift Gearbox. The solenoids mounted on the valve body are not available individually, so if you needed just one solenoid you would have to buy the entire Mechatronic assembly (valve body, solenoids and TCM) for about a thousand bucks.
Corvettes: Easy to Service?
I have been reporting on serviceability of motor vehicles from the viewpoint of a technician for many years now. I normally pick a car, truck, van or SUV that sells 100,000 or more units per year – cars you will almost certainly see in your service bay.
Corvette is not in that category, but every boy or girl growing up after WWII remembers a Corvette as the coolest car in the world. They certainly have a mystique about them that made many of us, at some point in our lives, want to buy or at least get behind the wheel of one. But when they need service or repairs, do the technicians love ’em or hate ’em?
Modern Transmissions & Vehicle Security: Where is the TCU?
Engine-management computers have moved from the passenger compartment to under the hood to the top of the engine to reduce wiring (copper) and assembly costs in vehicles. Many of you may have seen manufacturers even begin to place the transmission control unit (TCU) inside the transmission (Figure 1). I am not aware who was first to use this technology, but I have seen it for many years on Mercedes-Benz vehicles.
Statistics – Who Needs Them?
You do, but only if you aspire to a higher level of success. It’s amazing how some business owners count very heavily on statistics but others rarely, if ever, look at their numbers.
