When Things Go Wrong
Customer service in the transmission and auto-service business begins when something goes wrong. If nothing ever did, there would be no need for it. So you have to figure that in virtually every after-sale customer-service situation, somebody didn’t get what they either wanted, needed or thought they were entitled to. That means that emotions are running high in every one of these instances. People range from being mildly upset to fighting angry. Often an otherwise calm, friendly individual can turn into a monster before your very eyes.
Reflashing Job Takes a Different Turn
He goes on to explain that it is a 2002 PT Cruiser, and it starts overheating whenever he runs the A/C and sits in traffic. He traced it down to the fan relay and replaced it with a new one. Apparently that solution didn’t work, so he was trying to bypass the relay to get it to turn on the fan, and smoke started coming out of the computer. So he got a used [computer] and put it in but it still wouldn’t start. He said D.J. said it needed to be flashed and that I could do that. He added, “I could bring it to you, as I already have it loaded on a trailer.”
Another One to Add to the List
Throughout the years I have produced articles revealing various types of self-inflicted injuries that ate up time, energy and money unnecessarily as a way to forewarn others so they can avoid this pitfall. Many thanks go to those who have revealed their mistakes to us so we can share them with all of you, as well as the ones we have discovered on our technical hotline.

4R/5R55E: Engine Stall on Engagement after Rebuild
A local general-repair garage brought a 5R55E transmission and converter to a transmission shop for a rebuild. The transmission came out of a 1997 4.0-liter Ford Explorer with 216,456 miles on the odometer. The shop had the correct rebuilt transmission and converter in stock, so exchanging the change-over parts was all that was necessary to return the unit to the garage.
4L60-E EC3 TCC Control and Adapt
While I was helping a co-worker repair a TCC slip, we analyzed some graphs and noticed some interesting info on how the PCM behaves and how it “sees” and adapts for a TCC slip.

Speculating in Petroleum
The lifeblood of any machinery with moving parts is the lubricant. Without the proper lube, serious failure occurs quickly, yet few technicians have taken the time to really understand such an important commodity. Just as parts have proliferated dramatically with so many transmission and transfer-case designs in the market, the different specified lubricants are now almost too numerous to stock.
A Tale of Two Fords
Our first tale is one of those situations in which you are in the middle of nowhere and all of a sudden a warning lamp comes on. This person, whom we will call Mr. Public, was driving his Ford Taurus equipped with an AX4S on a lonely stretch of road at night when suddenly the transmission-temperature lamp came on. Fortunately, Mr. Public was able to limp the car into the closest town, where he took the car to the local transmission shop the next morning.
