get basic maintenance uptodate before diving deeper.

refresh all fluids, including power steering wink wink.

change spark plugs.

clean map/iat sensors w maf sensor cleaner.

clean throttle body.

make sure all hoses/turbo piping is secure and no leaks.

reset the pcm so it learns your driving style.

then reevaluate.

Question, I've checked the box on that list minus the power steering fluid, I even put a diff transmission with far less miles in it. Same things. It has a 3 bar map and an sct tune, I'm new to all the tuning and turbo car stuff. I did in fact blow a boost hose yesterday so I'll be fixing that tonight, what else can I do to make the shudder and slippage go away

Out there somewhere
Yes, the solenoid strategy needs to be programmed into the PCM. A transmission shop should know this. A mechanic shop may not.

or simply disconnect neg cable for 40+ minutes. i prefer this over a software reset as some things tend to stick as vehicles age.

as far as tcm reset, you can do this with service functions in forscan lite, as TM referred to above. this software runs on android or ios devices, but android version you have to download directly from their website forscan.org as it has been delisted from the Play store.

most go with a bluetooth obd adapter/dongle to connect to the vehicle, such as veepeak, obdlink mx+, etc. forscan favors mx+ on their site of course, as it is a very capable adapter but does cost $$$. i have been running an MX for 9 years now and an MX+ about 5. their warranty IS worth the paper its printed on, imho. https://www.amazon.com/OBDLink-Bluetooth-Professional-Grade-Diagnostic-Performance/dp/B07JFRFJG6/ they go on sale sometimes.

the veepeak is an alternative https://www.amazon.com/Veepeak-Bluetooth-Diagnostic-Supports-DashCommand/dp/B011NSX27A/ but this one works only with android. i have one but hardly use it.

Another vote for the MX+! Yes more expensive but it has an automatic power down and power up which is very nice. I tend to leave it in as I like to monitor stuff in real time using Torque Pro.

I had the same symptoms, and first suspected it was the Torque Converter. To make a long story short, it was the TC.

I suspected the same. I'm dropping it off tonight to get it looked at for that and the blowing sound behind the dash under acceleration load.
