You're correct, I mean shift into drive. (Previous Wrangler was manual, it's stuck in my head - apologies)
Here's exactly what's happening.
- Parked, put in reverse and back up about 100 feet
- Pull on to side street in reverse
- Switch into drive
- Let off brake
- Without touching gas, car feels like I pushed somewhat hard on the gas and jumps (for lack of a better word) forward a few feet before calming down
Maybe it's because I'm coming from a manual? Our other vehicles don't do this, maybe I should try holding the brake longer. I'll experiment a bit more today.
Hope this explanation helps.
