Been having some issues with my tranny after it was rebuilt last summer. From a stop, there is a hesitation when going into the throttle, then really long hesitations from 1-2 and 2-3. The guy that rebuilt it is about 5 hours away. Is there something I can do to fix this? Or can a shop take a look at it without killing my pocket?

This is my DD with very few mods on it.

Any help/advice is greatly appreciated
