NHTSA Complaint #11484624 — 2012 FORD F-150

The safety recall for my 2012 Ford F-150 that was to fix a sudden downshift on the truck did not work. From what I have read; the root cause for this random downshifting is identified by as this: a defective bulk head connector. When trans fluid leaks past the bulk head sealing rings it can disrupt the transmission's output speed sensor signal. When this happens the ECM automatically downshifts to second or first gear. to fix this issue Ford released a TSB that was comprised of a software update designed to prevent the ECM from automatically downshifting when the loss of signal occurs (I don't know what other conditions have to occur simultaneously). This fix is less labor intensive (thus cheaper) than replacing the actual bulk head connector assembly. Ford has released a revised part number for the bulkhead connector as well. The sudden downshift which has always been prevalent on this truck continues to happen, it’s a safety concern that is going to cost me a lot of money to fix that they should be fixing instead of programming a software update that is a temporary fix.
