So ive been reading around and havent found much so here is my problem. I get through 1st and 2nd ok but when it is trying to get to 3rd gear it revs higher than usual and eventually shifts, then seems to shift to 4th to early. the trans fluid isnt burnt but not new, no codes pop up on the code reader, i disconnected the battery to reset it, didnt help.

any ideas?

Thanks
