Watch: 6R80 Pump Noise

Diagnosing noise in a transmission starts with figuring out what type it is and when it occurs. Noise can include whining, moaning, groaning, etc. Noise can occur in park/neutral, in gear setting still or driving down the road. In the case of a 6R80 a bearing growl may be heard at all times and not be the geartrain. Upgrades have been made to

Diagnosis: Do the Homework

Occasionally in diagnosing transmission problems technicians are faced with challenges that force us to look beyond the transmission control system.

Programming Not Included

A customer recently brought his 2011 Ford F-150 into our facility after a general-repair shop (not a specialized transmission shop) had just installed a used transmission. His truck was a 4WD vehicle equipped with a 5.0L engine and 6R80 transmission. When the customer picked up the truck from the previous shop he was told that the transmission was installed and everything was fine, but it still needed to be programmed (the shop didn’t have the equipment to perform this important step).

Another Case of Brutality

Our technical help line is now experiencing a different transmission that can have a variety of severe shifts complaints. It is with Ford’s 6R60/80 transmission. We received one such call from Mr. Transmission in Louisville, Ky., with a 2007 Explorer Sport 4.6L that had 65,000 miles. It shifted fine until you went for passing gear out of 4th. The shift was so brutal that it felt like the transmission went into reverse. There were no codes present. An entirely different call was a complaint of firm shifts and during full throttle kickdowns the vehicle speed signal would drop to zero. It too did not have codes. Yet another call received, all the shifts were extremely severe and it had a variety of CAN BUS codes stored.
