I thought I’d wake up my 2.3l today since the snow is over and were getting better weather already in my area. Since late August, the car has only been started and ran up to operating temps. Avoided driving it due to salt usage on the roads.

Today I start it up, get out on the road and up to 55mph, instantly notice the rpm’s are at 3k and climbing, trans isn’t shifting into third gear. Crazy thing to me is, the car ran flawlessly last year when it got parked.

Anybody have any idea where to...
