"Hey guys, just a heads up for any 2006 35C18 IV Fright Festival owners out there - I'm experiencing some weird gear shift issues on the highway. It's not happening all the time, but my car seems to be downshifting really early and it's a bit jerky. Anyone else had any similar problems or know what could be causing it?"

"Dude, my 35C20 had some issues with gear shifting when I first got it but my mechanic said it was just a software issue. Had him update the TCM and it's been smooth sailing ever since. Has anyone tried that on theirs?"

Yeah, I've had my share of weird gear shifts with my 2006 35c18, especially when I'm cruising at higher speeds. It's like the transmission's hesitating for a split second before kicking in. Have you tried adjusting the throttle pedal or maybe checking the transmission fluid levels?
