I don't think there'd be a problem if you let Will know that you had the shift kit in there. He'd be able to tune around it.

Yes, the transmission on the 2012+ does not have a removable pan - but it does have a drain plug. So, you simply drain and fill - just like an oil change...

Just make sure you use Dexron XI flud! Also be careful when filling the transmission fluid - the transmission has to be in a certain temperature range to get a good fluid level reading on the dipstick (180F-200F, if I recall correctly). You do NOT want to overfill it!

The hard shifting did not throw a light but, did store a code p1811 shown by a scan tool.

I plan on getting an overkill tune but if that won't help, what do i do from here?
Have you checked the fluid level and what type of fluid did you use?

the kit is cheaper but the pcm has other benefits.. as far cleaning it out.. brake cleaner and lint free cloth is what I used on everything including the pan..

zerialz One more thing.. It's imperative for whatever reason to scuff the shit out the walls in the accumulator where the pistons are with an emery cloth or whatever abrasive material you have.. I believe I used sand paper and ensured no residue remained.
