I used engine off coasting during my entire 126 mile trip today, and couldn't tell the difference between shifting from neutral with bump starting or with the engine already on.

Bump starting up to 35 mph was very smooth and made no difference at all in the speed. I didn't try with the engine on at that speed. However, bump starting at 50 to 60 mph continued to have the same jerkiness as shifting from coasting with the engine already on.

I did manage quite a few shifts today with no loss of speed (engine on or off), which is quite encouraging. Jedi_sol's comment to shift slowly can be helpful to find out where the mistake is happening that's causing the loss. I will practice this more the next time.

Thank you for all the helpful suggestions!
