2016 ecoboost automatic transmission problem

[05 GSXR 1XXX]

Yes I searched, both Google and here.

2016 ecoboost with performance package
Cobb stage 1 93 tune
Resonator delete
Muffler delete

All mods have been on car maybe 2-3k miles
(I drive this car daily 80 miles round trip, I have beat on it maybe 10 times, no tracks at all)

3 days ago I noticed when I left for work my car revved then slammed into 6th Gear. It has continued to do so but I can predict the 5-6th change and throttle off and it will go into gear easier.

I changed my tune from stage 1 to stage 0 (stock driving) and it's still doing it. I will Uninstall the tuner tonight to see if it makes a difference.

Has anyone else had this problem?? Pretty bummed out I've only had this car for 6 months and this is starting.

Just wanted to follow up with this.

I took the cobb tuner off and back to factory tune. The problem went away instantly...

Haven't had a chance to contact cobb about this, Not sure if the ots tune itself went bad or the settings were too high for line pressure causing pump failure.

If I get around to contacting them if they have experienced this ill def report back to help others in the future.

Sucks driving around on factory tune :/

Final update:

Spoke with Cobb, Latest version OTS V400 handles problems with automatic transmissions.

I'm happy to say they V400 tune is working flawlessly! Drives like stock but has all the power when I need it!

Great customer service!

Thanks Cobb!
