Well my car has almost 70k now and has the alpina B3 v2 flash and I mean I like power and am running a BEF and map 7 so 20 psi of boost... Some other small mods just did the alpina B3 v2 flash like a week ago and sometimes when it shifts WOT 1-2 it shifts hard sometimes it shifts smooth and sometimes it shifts smooth but rpms jump up right after the shift (slippage). No codes at all. Sometimes it seems like something hops when you downshift hard to like 2nd too. Idk I have a warranty good till 102k but I eould have to switch everything to stock and flash everything back. (VRSF chargepipe VRSF 7 inch FMIC DCI Jb4 Back end flash transmission flash and run it out of E50+ and fill with premium). How hard is a transmission swap on an 08 xi?

Have you tried a fluid refresh? Trains swap not incredibly hard, but not sure hey you're worried about difficulty level given you have a warranty.

Just a pain uninstalling all the mods...

So free trans or pay for trans. It'll be harder to install new trans than it will be to replace mods. Plus you have to buy said trans on top of pain.

Chance they may say mods were installed too had to do cutting for the FMIC. Idk what they can all look into with an aftermarket warranty but also have a back end flash but there is no way the transmission would slip under stock settings....
