Hello, My Jeep made a "cachunk" sound the other day...the transmission appeared to be stuck in 2nd/higher gear and would not change...my check engine light came on and the OD button would not light up... and I checked the code "P0303"=misfire on #3 cylinder...here's where the mystery starts..I turned the iginition off and the check engine light went away, the OD light would come on when I pushed it and the transmission returned to normal...uuugghhh! This seems to only happen when I do interstate driving (70-85mph)...PLEASE HELP WITH ANY EXPERTISE!!
2004 TJ SPORT
4.0L
AUTOMATIC TRANNY

THANKS!
