An Identity Crisis
Some Ford vehicles using the 5R110W are having an identity crisis. Let me explain. A 2010 Ford F450 Rollback with a 6.8L V-10 gas engine comes into Walkers Auto Trans & Repair with a complaint of a loss of power and transmission not shifting. When the truck was scanned it showed fault codes P0720 and P0722 for the output speed sensor. Scan data also showed that all transmission speed sensors read nothing.

2012 KIA Optima 2.4 Hybrid
Not often do we get the opportunity to work with a tech that is having issues with a transmission in a hybrid vehicle. Not too long ago, Gerald Campbell had the chance to do just that with Carlos Costa from Transmission Technology. He had a 2012 Kia Optima 2.4L Hybrid using an A6MF2H transmission. There is no torque converter in this transmission. It does have an “engine clutch” and an “electrical motor” that sits in the area where the torque converter would be (Figure 1). The vehicle came into the shop with a “Stall on Engagement” complaint with repeated “Engine Clutch” burn out. In fact, when the trans was removed and disassembled, the engine clutch was smoked, and the clutch plates frozen/welded together.

The P0776 Twist
Tom from “Transmission Shop” in Minnesota had a customer come in with a 2012 Honda Odyssey with a six-speed BYKA transmission experiencing erratic shifts. It had an intermittent and inconsistent 2-3 shift where sometimes it would have a slight flair and bump while other times it would experience a large flair and a bump. Other times it shifted into 3rd then neutral and back into 3rd.
