Hey and thanks for note! Sorry I am late here, truly. Yes, manual.

I am not sure what gear this happened in, as I sometimes start in 2nd. It had to be 1st or 2nd, JERK, BOOM, then all fine. Very unsettling. Someone suggested I may be leaking trans fluid, as something has been leaking. I need to find mechanic here who won't overcharge. It MAY be popping out of first, and this has only occurred 4 times in the past year. But now, two occasions a few weeks apart. I am at the point with my baby car that "it's always something."
