back in 2010 i purchased a 2005 GTP Comp G with a bad transmission,rack and pinion etc it was a nice car as far as appearance goes,but mechanically it was very neglected,with that being said i had the transmission rebuilt a few months ago,now its starting to slip keep in mind i dont drive this car hard so im wondering what could have went wrong? i hate the fact that my car is in the shop,but the good thing is i had a warranty,mechanic said the transmission fluid smelled burned when they removed the transmission if that helps any
