Transmission Issues after tune

[Walph_5.0]

Hey guys! Fairly new here but have browses this forum for awhile and I’m kind’ve stuck, I loaded my E85 tune from PBD tonight and everything seemed to be fine other than the trans is really jerky when going into reverse and when going to drive the car will say 10th gear and jerk into first, as well as not shifting out of third gear at all, wondering if any of you guys experienced anything like this, and if you guys had any tips or tricks to help? Thanks I’m advance!

What year is the car and what mods? What tuning device are you using? You didn't have any trans issues at all before the tune? I haven't had this happen and I've uploaded and changed back and forth on PBD tunes probably 30-40+ times. My very first tunes took a long time to get dialed in though I had a lot of issues in the very beginning but my car was one of the earlier 2018's that they had tuned and this was in 2018.

2021 GT Just a corsa Catback and my catalytic converters are gone, no issues before the tune and I’m using the SCT X4

On my '18 10R80 the tune from Procharger was absoultely perfect including part throttle acceleration. Only made 525rwhp. But it the search for more power, I added injectors, BAP, pulley, etc. Made a lot more power, likely up dear 650 or so. Tuned by PBD, but it didn't shift in a way I liked. PBD was good at helping me, but in the end, I just lived with part throttle shifting including sometimes it would not shift at all during WOT!

I wrote it off to the fickleness of my 10R80. If I had taken the time to constantly go back to PBD for tweaking, it might have been OK, but I ended up returning the car to stock where it drove perfect again.

Not with stick, the point being the more a car drives the driver. An not the other way around. The more likely a driver will need to take a back seat for the ride.

Interesting enough mine won’t shift out of third at all !

Put it on a battery charger then flash back to stock, then reflash your tune. SCT takes a long time to flash and if battery voltage drops strange things happen.

Gotcha, do you think a KAM Relearn would help too in anyway?

Never hurts to do a KAM reset after loading a tune.

Something is not right. I wouldn't drive it until you get a corrected file. Sounds like the wrong strategy was loaded or something.
