That is bizarre..Do you hear the engine rpms going up (Sound) or just seeing the Tach jump ?

Ugh. I went to my mechanic today, They ran the diagnostics on it...NO CODES came up. I took it for a drive with the consult connected, still nothing. They have no idea what is wrong with it. I'm lost and everyone i've taken it to has no damn idea. Sucks. lol. I'm thinking revolution sensor?

Does it pull when the tach goes up or does it seem like the transmission is slipping or not engaged ?

it pulls when the tach goes up. The transmission shifts quite well.
