Gear up-shifts from 1st to 2nd (usually occurring between 2000-2500 RPM) from dead stop but ONLY when I "ease" into traffic. However, if I gun it, this does not occur. Also noticed that quick downshifts from 2nd to 1st, then back to 2nd (as when your making a turn) does not yield the "slipping/bogging" I previously mentioned. Beyond 2nd gear the car runs smoothly. No codes displayed. Car has ~ 92k. Tranny was just replenish with about a quart of oil. My mechanic did noticed some minor oil leakage by the turbo oil lines. What's your Dx?
