Troubleshooting RFE overdrive clutch failure: Three key areas to check
Fighting overdrive failure in Chrysler RFE transmissions can be a frustrating task. You build the unit, and a week later, it’s back with the overdrive clutches burned up again. It happens with every one of them, from the 45RFE, 545RFE and 65RFE to the 66RFE and 68RFE. You have replaced the valve body and double-checked
The technician’s duty to the customer
I want to talk about some of the recent trends of particular cars and trucks that we see showing up at repair shops for work to be done. It seems to be a perfect storm of high used car prices, lack of new car inventory, and a bit of economic uncertainty that brings us to
Shop profile: DL Transmissions has leveraged a new location into significant success
Location, location, location. It’s commonly cited as a real estate motto, but really, it’s essential for any type of business. Whether it means being in close proximity to as many customers as possible or simply being in a visible or noticeable location, it can be a key to success for a transmission repair shop. After
The 6R140 torque converter: Common fault codes and how to rebuild
There are many reasons for converter clutch slip codes to occur in vehicles equipped with the Ford 6R140 transmission. One is bore wear in the valve body with any one of the three valves related to converter clutch apply and release. Low line pressure could be another. But there is a third that is inherent
Shift Pointers: Getting the 10R80 shaft
The Ford 10R80 family of transmissions has become known for the CDF clutch cylinder sleeve moving out of position. An updated drum has been made available by Ford with a “no-walk” backing lip to prevent repeat failure. After this cylinder has been replaced, there still may be another problem still lurking in the transmission that
TCRA 2023 annual meeting in pictures
I’m not sure where all of the years went, but it was a quarter century ago that Corky and Carole Meyers turned an educational user group for their TCRS converter rebuilding equipment into an association of converter rebuilders: the Torque Converter Rebuilders Association (TCRA). The initial meetings of the association took place in Reno, NV
Volkswagen dual clutch transmission and direct shift gearbox: What you need to know
Most of the drivers who own a Volkswagen car or truck with a Direct Shift Gearbox (DSG) will not know they have a dual-clutch transmission connected to the engine. Most of them will think they have an automatic that gets excellent gas mileage. It is not until a transmission component fails or a service interval
The evolution of diesel transmission maintenance
It’s no longer a secret… heck, it’s no longer that special for a diesel engine to make 1,000-plus horsepower. It’s become commonplace, and due to that increased capability, it seems that these days, OE manufacturers are rating transmissions at their absolute limits. As soon as you add a little more horsepower or work your truck
Diagnostic tips for the Ford 6F35
We have all experienced repairs that seem to “go down the rabbit hole,” as we call it. Our subject today is one such issue: a Ford 6F35 transmission with codes P073D or P177F after repair and a complaint of trying to go into Reverse while in Neutral, or a bind in Forward when cold. This
Diving into electrical testing and wiring with the 948TE
We had a 2014 Jeep Cherokee come into our Bellevue, Neb. facility with a transmission that would not shift. This all-wheel drive vehicle was equipped with a 3.2L engine and a 948TE nine-speed transmission. I was informed when the vehicle was dropped off that they previously brought it to a different shop for this same
Shift Pointers: Park Wiggle Movement
The Ford 6F35 transmission uses an internal Digital Transmission Range (TR) sensor (Figure 1, above) to provide a fixed frequency duty cycle to the Transmission Control Module (TCM) for five different manual control lever positions. They are Park, Reverse, Neutral, Drive and Low. The TCM uses this input to influence line pressure control, shift scheduling
The transmission repair industry: Globally integrated
I recently read an article reported on the Global Newswire that finds the world’s transmission repair aftermarket is continuing to grow. In that article, the authors found that what was about $188 million global industry was expected to approach $235 million by 2028. There are certainly differences among the various nations in the units in
