New transmission followed by constant CEL

Recommended Posts

Contacts on the barometer and MAP sensor do not cause the transmission to make noise. That is usually caused by bad bearings in the transmission and Ford replaced a fair number of these early 2013-14 transmissions. Dealers did not service them. They were told to remove them and replace. Maybe that's changed, I doubt it. Has the transmission stopped making the noise? There are all sorts of problems that can crop up in a major repair that can turn on a CEL when you remove and replace a transmission. The 2013's had too many early problems; transmission failures and oil leaks, air conditioning duct mold, etc. If they replaced the transmission it's probably OK but it sounds like they didn't.

Removing and replacing a transmission is a big job. Lot's of things are unplugged and moved around so there are lots of opportunities for damage or incorrect procedures. The CEL should leave DTCs that should lead to a proper repair. Insist upon it. It's common for dealers to do a crappy job. I had a '78 Olds diesel wagon that blew three head gaskets in the six months that I owned it. Each time I got it back from the warranty repair I spent about an hour fixing stuff in the engine compartment that they hadn't done right; crimped and mis-routed hoses wires, etc. About six months after I sold it my wife got a call from the new owner wondering about the Olds dealer's competence. Apparently it had blown another head gasket. When they were placing the hood back on the car they dropped it through the windshield and were currently waiting for a replacement.

CELs are usually emissions related items so broken or cracked hoses etc., are a common problem. Once they fix the CEL problem you're probably OK. Did they swap out the transmission or take it apart and replace the bearing? If it was the latter, that's a first to my knowledge. If they didn't replace the whole transmission, I'd get rid of it. Who knows what parts of failed bearings got loose in the transmission. Maybe they have an approved procedure now.

You transmission made by Ford is an "improved" version of all the previous transmissions that were built in Japan by Aisin, the "Borg-Warner" of Japan. Between the 2005-12 Ford Escapes and 2010-12 Ford, Mercury and Lincoln hybids, Aisin supplied about 200,000 transmissions. I have never heard of any of them failing particularly the 2010-12s. I expect these Aisin transmissions to be intact in junk yards 50 years from now with the rusted remains of a car around them.

A little note about the GM diesel cars. The engine was not just a diesel 350 cu in. V-8. The crankshaft bearings were 1/2 inch thicker and the rod bearings were 1/4 thicker. The block had the same layout and the channels between the cylinders and the water passages were the same and that's where the gaskets blew. At the end they put very high strength high torque head bolts in and that stopped the blown gasket problem but by then the damage to the car's reputation was complete. The fuel injectors were also cheap and unreliable.The injectors and fuel pump are the heart of a diesel.

It's common in early 2013+ FFH's and C Max's. It's believed to be bearing failure. It is a manufacturing defect. The failure rate or percentage is unknown but it should be zero.

Seriously? I doubt there is any transmission ever built in the entire history of the automotive industry that has a failure rate of zero.

Seriously, yes. A transmission like this should never have any early failures. Certainly not what we've seen on these forums.

You have modified your original statement by qualifying it with "early failures" which may be more realistic when considering the mechanical aspects of this transmission. All mechanical devices will eventually fail given enough time. A manufacturing defect, even when extremely rare, can hasten that failure. When electronic devices fail it usually occurs early in their life and this transmission is full of electronics. Finally, this transmission is controlled by large quantities of complex software and you will never ever achieve zero defects in complex software systems.

 

A low failure rate is a reasonable expectation and a requirement in order for a manufacturer to remain competitive. A failure rate of zero is not a reasonable or realistic expectation.

The transmission is guaranteed for 8 years or 100,000 miles. Are you within that?
