Car is a 2017 with about 30K and starting to get the dreaded "shuttering". I ordered the Mobile One "blue label" and filter/gasket. Once I get the pan off cleaning it is easy. Wondering if I could or should spray anything on the bottom of the exposed transmission. Valve body, filter removed, etc. Something like brake cleaner or otherwise or is that asking for trouble. I am sure there will be some sort of small shavings I can wipe up with a microfiber just curious if I hit is with something like brake cleaner which dissolves would hurt? Or just change fluid, let drain for awhile, fill and be gone. LOL

Did you read the TSB? You are starting to experience the shudder, so your TCC clutch is already worn in spots, you want to get all the old hygroscopic fluid out of the trans, otherwise the accumulated moisture in the remnants of the old fluid will continue to erode the clutch, and the shudder may easily remain or return.

Simply letting the fluid drain may not be enough at this point, you want the flush the old stock out. If you still want to do it yourself, at least here is a video to help with the final fluid level check (underfilling will be bad, overfilling probably worse):

Yes sir. I am not going to clean anything but the pan which should get most of the shavings. I will wipe it down. If I dont see a change I might do the job twice. I spent $145 for everything. Fluid is only $7.19 a quart so I can do 2 changes for about $200 as opposed to spending $1K at my dealer.
