2018 Transmission issue

[RustyR]

Today while driving out of neighborhood had a hard shift and the wrench appeared. I kept driving as a hard shift has not been unusual. Unfortunately, when I got on the main road started having some very hard erratic shifting, even had a hard time going up a small hill. It's the Rousch edition so not 100% sure if it has anything special with the transmission. Wondering if I should have it towed to the dealer?

Depending on the DTCs setting it may need to go back to Roush. The dealer can’t fix what Roush modified.

My 2018‘s in the shop right now and they’re heavy duty mechanic at Ford said could be a piston in the transmission body that’s failing, mines shifting all over the place at the wrong time hunting for gears rough shifts shutters ECT. Anyway it’s in Ford‘s hands under extended warranty. 65,000 miles
