7AT Issue Help Guys!

ItsErnie · 02-08-2016, 12:11 PM

I posted this once before, my car has been doing something strange in 3rd gear, Im not sure if its slipping or what? My car is a 2014 with 16k miles. I'll post a video to see if you guys can figure it out because I took it to the dealer and they said nothing was wrong with it. https://vimeo.com/154614204

What's it doing? Can't really tell in the video

MagmaRed370z · 02-08-2016, 01:16 PM

Please describe the issue.

Take it to a different dealer.

The problem seems to be that you got AT over MT haha if what you are referring to is that little glitch with the rpm where it kind of like falls a little, I'm thinking its just the computer shifting lag. Essentially your demand is faster than its processing OR I'm also thinking its a sudden loss of power either due to high temp air getting in the engine, or lack of fuel in the chamber, or some other reason. I mean it's hard to work with but things like this would happen with my last car and this car.

I would shift into 2nd and suddenly the car would like lose power and feel very sluggish and forced. Also have an oil change done using royal purple I've tried other stuff other than RP and I'm not happy with temp limits, viscosity and performance in high temperatures haha.

Idk what your issue is... maybe I can take a guess... sometimes when I'm in a gear for example... 4th gear... I'll down shift and it would bring me to 2nd gear totally skipping 3rd... maybe when the computer automatically down shifts it and you down shifts at the same time you skip the gear.

OldGuyFla · 02-08-2016, 02:49 PM

The video shows that you are in drive. Does it do the same thing when you are in manual?

ped · 02-08-2016, 03:48 PM

So Ernie posts this and doesn't describe the problem and doesn't return to the thread (or is 4 hours not enough time and I'm jumping the gun)?

mishuko · 02-08-2016, 04:03 PM

cut him some slack... he could be at work and posted this at lunch.

or maybe he realizes he should of just MAN'ual next time.

btw in other cars I notice they skip gears when going slow but not sure what I'm missing here

lwpnfrisco · 02-08-2016, 05:19 PM

One thing I noticed, and correct me if I am wrong, but it appears the amber 'triangle' "!" to the left of the tach (Master Warning Light) is lite!!! Why would that be on while the car is running?

ItsErnie · 02-08-2016, 11:45 PM

Yes, the problem is that drop in rpms, it happens everyday, most noticeable after driving off in the mornings after a cold start. The car actually lunges a little too.

Does this drop in rpm seem like the tranny is slipping? It is a loss of power. Under any kind of acceleration and always in 3rd gear!

Slipping in the transmission normally goes the other way in the RPM range, known as a "flare", because the transmission isn't grabbing.
