Howdy all,
I seem to have had a similar experience as @
Deinonychus. I Was at the light making a left and as it turned green I pushed the gas and it goes into 1st gear but doesn't shift into 2nd, it just revved and I panic and stop immediately at the side of the curb and turned off the engine afraid that it might have a mind of it's own.
But two weeks before that happened I had the transmission fluid flush and put amsoil in it. As I left the ford dealer i immediately felt a hard shift from 1st to 2nd like I was being rear ended. I thought nothing of it as i read it was a common problem and thought that the additive they put in to flush the gunk out of the tranny before they put the new fluid was causing those hard shifts and after 100-400 miles the tranny will relearn itself and shift smoother. But the hard shift never went away.
So i brought it to the dealer the next day after that 1st gear incident and tell them that ever since they flush the fluid it's been shifting really hard from 1st to 2nd and that it rev out of 1st gear without going into 2nd gear. So the advisor says he needs all day on it and I leave it. I'm out of warranty on my 2013 with 72k miles. So I'm thinking it's the "molded lead frame" issue and is gonna cost 1-2k to fix.
He calls me in the afternoon and says the tranny fluid was low and the tranny tech says that's what caused it. I guess the last tech that did it didn't fill it to a proper level. So they completely redo the flush and put new fluid back in at the correct level and said the shop foreman test drove it and said all is fine and shifts smooth as glass. It did shift so much better as they probably reset the adaptive tranny computer as well as putting the correct fluid level.
Yes it shifts fine and much smoother now. But somehow I'm afraid the real issue might rear it's ugly head down the line as it did with some of those that were affected by the "Molded lead Frame" issue.
So I just wanted to put it out there incase it might help anyone, as checking the tranny fluid level is the cheapest to eliminate first.
I'm no expert and I just wanted your guys take on it? Maybe it is low tranny fluid maybe not?
Thanks
