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.

Another Heart Break

A 2014 Nissan Versa arrives at a shop on a flatbed with a customer complaint of a loss of engine power. The reason it was brought to a transmission shop is the type of engine power loss it had. In park or neutral, the engine can rev up to 2500 rpm easily. Even in drive with the brakes applied, you can reach stall speed torque with no power loss issues at all. But, the moment the brake is released to launch forward, as soon as it starts to roll there is an immediate loss of engine power.
