Hey guys 2015 tuned with pip tunes and no emissions parts. Was running tow tune and the 3-4 shift was violent like a rubber band slamming into gear. I upload the extreme tune and transmission shifts great for two weeks. Couple days ago the trans starts being weird. Rubber band shifts on 3-4 and also 4-5. Also feels like going into neutral then back into gear under partial throttle shifts. Any ideas or insight?

Which version of the tunes are you running? Almost sounds like it's a shift flare. If you have read any on here I'm sure you are aware of the 15' transmissions not having as many clutches as the older transmissions and I do believe those are the 2 shifts that are problematic.

less like a flare and more like the converter locking in when it shouldn't be.or locking then unlocking (7.2 tunes)

How does it lock in 3rd? I wonder if it's similar to the IDP tunes. Basically it feels like it shifts 3 times when technically it's only 2.

Locks hard in 3rd. Watched it on the cts. Seems to lock at too high of rpm.

It actually feels like a shift when it does it.

Yeah the high lock in 3rd is noticeable for me, but other than that, shifts fine in anything under extreme. Extreme, well the tranny doesn't like extreme...

Same thing here, I emailed PIP and they said they were having that issue with 7.2 and to switch back to a previous version. Back at 7 and all is good.

Was it doing it with the tow tune as well? Last I talked to Pip only the Performance and Extreme tunes were 7.2, All the others were still 7.1. That may have changed however. This was a month ago! Could yall get any vids of the Shifting?

The extreme was the only one they sent me. Told me all the other tunes were the same. That was three weeks ago. Haven't ran any version of the extreme, performance is the only tune I've used so far. To stay on topic, I do get some shift flairs every once in a while.

I just double checked and He sent me the 7.2 tunes on July 12th and it was the Performance and Extreme files.
I had quite a few shift flairs with the earlier versions of P** tunes, But nothing with the later versions. I've had 1 shift flair with I** when I first flashed the truck, However I haven't had it again. Now that I say that it will start doing it again I'm sure lol.
Have you tried reflashing the truck to stock then re doing the load first and then the tune? These 15's are so darn finicky.

No, haven't reflashed it since I got the 7.1 tunes. It doesn't flare often. The only problem I have with the tunes is the lazy shifting. Give me some quick-positive shifts with a TC that stays locked and I'll be happy. Haven't had that since my 03 with Tadds tunes.
