I’m seeing that my 2019 gt is doing the same thing has the dealer said what it may beAnyone experiencing strange behavior from their 10-speed? I've got an EB convertible, and an EB coupe, both 2018, and they display the same behaviors in some instances, while the coupe does strange things that the convertible doesn't. The most alarming behavior from the coupe is a pronounced 'lunge' when moving from Park to Drive, (occasionally) after the car has been sitting for about an hour. The microsecond the shifter hits "D", the car lunges forward without the typical engagement delay. Engine at normal, hot idle speed. It's done it a few times going into Reverse from Park, as well. I don't know if this is a programming glitch, or a mechanical issue. The convertible has never done it. Anybody else seeing this?
I just bought a new 2018 mustang GT with 10 speed automatic, and I’m experiencing the same issues! In the mornings , going from park to drive or from reverse to drive , the car wants to jump forward like crazy. And when I’m coming to a red light or stop sign, the last few gears seem to down shift roughly , and I do feel inconsistency in the brake pedal , like the car has a motor brake or something. When it downshifts into first gear while slowly rolling , it still has that jumpy effect wanting to jump forward. Was your dealership able to fix problem? ThanksI got a 2018 ecoboost automatic with 4300 miles and lately its been really annoying driving it because when you put in drive and it will "lunge' hard so you have to press the brake hard also so to stop it from "jerking" back forward. Put in reverse and it will do the same "jerking" and you could hear the transmission engaging hard. What if somebody was walking in front of your car and you did not press the brake hard. For sure they will think that you are trying to run them over.
When driving and you need to slow down, the car will downshift maybe 2-3 gears down and you could feel that it's doing like an "engine brake".
I went to the dealer yesterday where I got it and they have me scheduled on Nov. 5 for their tranny mechanic because they have a lot of workload. This is happening more often now being the reason I went to the dealer.
I hope they can fix by software and without taking the transmission down, still being a brand new car. I have not tried the sport mode yet or any rough driving/starting cause I still "babied" this car and this happens. I need to borrow the "lunge" word from cbdallas because this is the exact word that characterize the annoying problem.
Update on my 2018 ecoboost "lunge" and "jerking" problem. The service department of the dealer took my car and kept it for 2 days (just to be sure) and called me that they reprogrammed it. It drives much better but there is still a little bit of downshifting you could feel when slowing down and the idle speed is a little bit faster compared previously maybe around 650-700.I just bought a new 2018 mustang GT with 10 speed automatic, and I’m experiencing the same issues!

My eco just have 3700mile and it was jerking every time from P to D, when I broke speed fast you can feel a thumb! I dropped off the car at the dealership now on it does time to time, the service manager described the issue like a normal for ecoboost and they can’t do nothing about it I’m really madAny update ?
I own a 2018 GT Premium and I noticed a slight jerk from P to D , it’s really nothing to be concerned about ( for now ) and usually when it’s warmed up , it doesn’t do it , shifts thru the all the gears fine .I've got 6500 miles on my 19 ecoboost. My transmission does not jerk coming to a stop or going from park to reverse or drive. The first week I owned the car you could feel the transmission doing weird stuff. Now it shifts and drives great. Took it easy on the car for the first 2000 miles. Most of my driving is highway between a crawl and 80mph. I switch between sport and normal often. My transmission is holding up ( fingers crossed ).
It's good to hear from you guys, we always hear about the problems and never from the thousands of people that are not having them. I'm not saying the problems aren't real, they are, but I believe they get a little over exposed if you will. My new wheels will be here soon, hopefully I'll be on your side of the issue.
Ordered a '19 GT Premium PP 401A 10R80 race red Mustang. It was built during the first week of February and was supposed to be delivered by the 15th, but it's setting in Flat Rock because of "weather". It's Michigan for goodness’ sake, aren't they used to snow? Go Figure! I put my Black '16 GT Premium PP 401A MT-82 full bolt on car up for sale and it sold right away, now I'm without my Mustang and don't really know when I'll get it. Oh well, it will all work out. Its just tough having to wait for it.What wheels did you go with ? I'm upgrading my wheels real soon.
