3.3TT vehicle doesn't shift gear under decent acceleration

[CKeeler]

What does your dealer say about this?

I’m allergic to dealerships.

Haven't tried the dealership yet. Mines MY 18.

This happens to me in my 2020 GT-Line. I drive in auto transmission(comfort mode) and it sometime never changes the gear. Has to ease the gas paddle to make it respond.

Gas pedal? Or manual paddle shifter?

This post is very confusing.

Happens to me too. All modes, paddle or auto. It's only ever happened when taking a sweeper semi aggressively under hard acceleration. I assumed it was preventing the shift as to not upset the chassis mid corner. Never tried it with traction control off. 2019 GT1 RWD. Also I've never tried shifting while accelerating hard mid corner, it's after I let off and intend to go back to normal driving.

I just started experiencing this myself. Hard acceleration out of a clover leaf onto a straight, the car hangs onto what I presume to be 4th gear until the rev limit shuts fuel off...really aggravating to have half a second of no throttle at the merge point.

MY18 GT2, using sport mode in D, 12.4k miles, no mods.

Oil leaking... i don't know what oil it is

i found this during engine oil change. Does anyone have any idea what would leak through that? I wiped it to see if it comes back again. i am hoping it is from oil drain from last oil change which I had a shop to do.

stingerforum.org

I don't know if these issues are related, but ask your tech to inspect this seam next time you get your engine oil changed.
My car has transmission oil leak from seam between engine block and torque converter.

i did an oil change today, i do not have a leak at that location.

I've had that happen when trying to paddle shift during a period of higher load, a very few times at most. But based on that it is why I've not used paddles on the track at all. Please keep us updated once you get some feedback.

Same here: I found it VERY distressing on the track when the car would randomly decide "naw, I'm not ready to shift -- let's go to redline!". If your accelerating hard out of a corner and you "ask" the car to shift then it should shift! Auto only safe way to drive these on the track IMHO.

Yeah, automatic absolutely is the only way to drive it on the track, but we also need to understand that this is not a track-oriented car like a Type R, Focus RS, BMW M or Merc AMG series or something exotic and track-oriented, at the end of the day it is a 2 ton GT car, which in its stock form is not really suitable for heavy driving on the track.

I have now developed a transmission issue where under decent acceleration (without constant heavy load) the car shifts from 3rd to 4th really high up, normally it was around the 2.2k rpm mark but now it wants to go far over 3k. Hope it doesnt develop into something more annoying.

Has any one experienced this?
It doesn't happen always, but happens sometimes..
it happens when I take a ramp to highway and try to hit highway speed (70mph) before the ramp ends when I'm in Sport mode and shifting with the paddle shifters.
It is always 5th or 6th gear that won't shift to the next gear, and the rev goes crazy high hitting the red line
I have to release the gas and it will shift maybe 2 seconds later.
I've had the same problem, under hard acceleration in 3rd gear and then trying to shift into 4th and it won't shift, I have to back off before it will shift, really bites. This happens when I drive thru a specific curve while going uphill, using the right paddle shifter...

Alroght yall im throwing my car acknowledge into this ring. I personally believe that this issue could be a clutch one. Almost certain. That said there are many electronic parts to the dual clutch in the stinger. I do not understand the tech but i get that it works like a semi-auto tranny but can still get burned from improper driving. The car pulls the electric 'clutch' at slow speeds to save life at stop lights, could be a crossed wire that causes the tranny to hold on... could be clutch plate hatmonics at that certain rpm ... i just wanted to add to the discussion.

 

[DoctorStiches]

Also i have never experenced the delayed shift issue before and drive relatively hard with a few bolt ons. Always pay attention to how i sit at lights and avoid rolling at all even if it means im the only stop n go driver on the offramp ect.

Reigniting this thread by adding my car to the list. When this happens to me it's absolutely maddening, and it happens a lot. Sometimes it seems to hang for 5 seconds and that is FOREVER. I keep smacking the paddle to try and get it to shift, but once it decides it wants to, then all of a sudden it'll cycle through from 5th all the way up to 8th because I'm so aggravated that I've hit the shifter 10 times by that point. Doesn't matter if I'm using the paddles or using the shift lever. Anyone bring it up to their dealer yet to see what they say? MY18 base GT with Borla catback

I mean no harm with this.

How was the car driven?

I drive rather hard with multiple pulls through a few gears daily and my car is doing fine at 44k.
Always in 'manual' mode (gt1 the shifter tilts and locks* the tranny to only listen to the paddles.. sort of)
Stop and start always turned off.
Most often sport (always me)
A few mods but no tuning
I drive my 'other' car some days so it sits max 3 days at a time.
...there are alot of fast cars on the freeways in my area, luckily i do not(knocking on wood) have any police trouble as i am a safe yet speedy driver.....

But all im sayin is maybe these cars with issues may be driven the same way in silimar condotions.

Just food for thought

Sounds like you and I have similar driving styles.. almost always in manual and almost always in sport (or custom setting with sport drivetrain and comfort steering). 75 percent of my daily commute is on the freeway with cruise control so the only opportunities I really have to pull it hard is down the on-ramp. Happens almost every time I get on it at any pace. I do like to hammer it in a straight line when the coast is clear, but I usually do that in auto just because it hits the shift points where they should be.

I would love to see a resolution to this problem idk why

Ditto, I've only just now found this thread but have only just recently been driving in manual (maybe for the last 6 months). And now that I'm thinking about it.. I think it only happens if I'm already driving along at 40 or 50mph which would be in 7th or 8th, downshift to 4th or 5th and then take off. It doesn't do it if I start from a dead stop and hit the shifts where they would most likely be naturally occuring. Hmmm...

 

[DoctorStiches]

The way the car talks to the transmission could be involved. Like how the trans shifts down fast if youve already applied the brake pedal and up faster under throttle... a sensor error perhaps

 

[StingertimeNC]

i just experienced this problem. holding 5th gear and pressing the paddle like 5 or 6 times before it will shift to 6th. happened a couple times in the span of about a minute. was driving twisty roads and shifting up and down, maybe like 50-75% throttle. I do have jb4 and the pedal tuner. I was wondering if the pedal tuner is tricking the car into thinking I'm at like 90% throttle when I'm really trying to give it say 60% throttle. I turned the pedal tuner back to basically the off position, and that seemed to have an effect, of course I couldn't replicate exactly the conditions where it happened so I can't be sure. Like if the car thinks I want full throttle, but I'm not actually at redline, then it won't shift. Oh I also have a Borla Catback, and it's been on for just a couple weeks, but that can't have anything to do with it??
