Hello, today I was driving up a pretty steep incline have a few thousand feet on a paved road. I was pushing about 3500 rpm in 4th gear than an odd smell started to come from my jeep. It made it up the rest of the mountain fine than 3rd and 4th gear started to fun pretty rough like a little vibration while in gear. I finally reached my designation and parked it for a few hours and started her up again and now when shifting into all the gears at the beginning I get this un normal vibration that’s pretty concerning. It’s a 07 jk manuel transmission. Any thoughts?
