Hi guys, Unfortunately for me my transmission is slipping quite bad in to third gear. It will rev but barely accelerate then will eventually catch... im hoping it could just be the oil if ####ed....but i don't know how to check it? a little help? But anyway if it's not the oil im thinking clutch packs, so probably have to get the box recod. Roughly how much am i looking at for a 4 speed auto 2005 exec. wagon. pretty sure it's the 4L60 box. Cheers!
