2005 Mustang had routine automatic transmission flush done at 46k miles, prior to service no leaks, only complaints of noisy transmission. Now transmission leaks, noticed some oil at a few hundreds wiped it clean thinking it was residue from the flush. At 50k checked again and leak in worse and took back to dealership (jones Ford, n. Charleston, SC). Dealer refused to cover the repair of the leak, stating leak was not caused by routine maintenance they performed, although states they do these routinely and occasionally cars come back leaking from the procedure. Contacted Ford motor crc and they stated it is a dealership service issue. Dealership says it's not. Yet I'm out to pay for a repair bill CA. Between $700 and $1000 depending on damage done.
2005 Ford Mustang gt convertible. This vehicle has an automatic transmission that when accelerating will sporadically shifts from first to second gear with a extremely rough gear change. The rough gear change jerks the car forward with enough force to strain the passenger necks and accelerates the car unexpectedly which can easily lead to a frontal crash.
While backing from my garage, I put the shifter into reverse. The car will pause and then a sudden jerk into reverse. The automatic transmission was recently flushed at the Ford dealership prior to the start of this problem.
