Performance Peek
Transmission Specialties, General Manager Ken Kelly says, has an overriding philosophy that is a starting point for everything it does. “We like to be partners with our customers which is different than filling the role of supplier. As partners, when they grow, we grow. And, when we grow, by bringing them new products to sell, they grow.”
10R80/10L90 10-Speed Solenoid Function
The first thing to remember when replacing the valve body and/or just the solenoids is the TCM will have to be updated. This is very similar to what has been covered in the past with the 8L90 found in GM vehicles referred to as solenoid characterization. The 10R80 solenoids are similar to the 6R140W solenoids referred to as solenoid body/strategy identification.
How to do Impossible Things
49 hours and 17 minutes ago, 13 of my peers and I were beginning a challenge that was physically and mentally impossible. Broken into teams of two, seven on each team, we were to follow orders and perform various dreadful movements at the command of Navy Seal Special Ops veterans. We had all trained hard for eight weeks prior. Nobody knew what we were up against, yet we all showed.
BMW 530e Plug-in Hybrid
A while back, I compared a 2005 BMW 325 2.5 liter to the updated 2011 model and guess what? The newer one was harder to service. So the questions I ask working techs include: Do the automotive designers look at the ease of service when designing a new car? And are they getting better or worse to work on?
Multiple Causes for P0562
A customer brought in a 2010 Dodge Journey AWD with the high-output 3.5-liter V6 engine and the 62TE automatic transmission. With a little more than 83,000 miles on the odometer, the complaint was for no upshifts and stuck in 3rd-gear failsafe mode. This concern had started out as an intermittent issue but now had become more regular.

Leading by Example
One of my first lessons upon going into business for myself was that if I wanted employees to follow and respect me I had to show them that I was the real thing, that I was someone who knew what I was doing and one who would keep my word to them no matter what. That wasn’t always easy to do; first because in the beginning I wasn’t the real thing. I had never worked on a transmission till I opened the shop, and I had never been in a business in which I had any employees who answered to me or for whom I was responsible.
An Inflated Story about Erratic Shifting
After a wide-open throttle forced downshift and then coming to a stop, the vehicle would take off in third or fourth gear. A scan tool confirmed that the wrong gear starts were commanded by the TCM. The transmission would upshift from third or fourth gear to fifth and sixth gears.
The P0763 Headache
A call came in to ATSG’s technical help line concerning a 2009 Kia Borrego with a 3.8L engine using a 5-speed RWD transmission called the A5SR2. This transmission is very similar to the Subaru 5AT transmission, a derivative of Nissan’s RE5R05A transmission. Mounted on top of the valve body are the solenoids, a sub-ROM and pressure switch frame assembly.

Another Day at the Orifice
Modifying orifice size in valve body separator plates has been practiced as long as automatic transmissions have been in existence. From performance upgrades to attempting to fix problems caused by valve-body wear, opening up orifices can provide positive effects – but can just as easily cause unforeseen problems. To avoid unwanted results, it is necessary to know when to drill, what size to drill to and when not to drill.
