99 Durango 5.2 liter 4WD 186,000 miles. The truck runs just fine but when making a left hand turn if I accelerate through the turn the trans will slip for a moment as if it was suddenly in neutral.

I had the trans flushed about 50K ago. I took it in to get it flushed again and the tech said there was a small trans leak so I want to find out what's going on before I get it flushed again. I capped off the fluid about 2 months ago - it doesn't seem to be losing a lot.

Any thoughts?
