Greeting all, I recently purchased a 2003 xc70 for what i am hoping would be a song ( $750 at a local dealership) and i am running into issues with the tranny. On the ride home shifting was hard up and down and was also racing between gears. With no code pulled a local mechanic said there are major problems. once the tranny code were pulled it came up with 0100 - TCM miscommunication code as i understand. Today I pulled the battery to reset the TCM and surprisingly it shifts beautifully. i suspect that it may come back however, does any one have any thoughts or experience with this? Thanks in advance
