Hey guys I have a 2004 Sunfire w/ 26000 miles and a automatic tranny.
Every so often when I put it in park from drive/reverse the transmission( I'm assuming) will rub to like a little pattern like rub.rub< pause >rub.rub and it repeats till I put it in drive and then back in park. It can't be heard from the engine bay or outside, but inside its a very low rubbing sound, and with my foot on the brack I can feel it plain as day. Anyone have a idea what this might be?
Try a transmission additive. For the life of me I can't remember the name of the stuff I used, but if you go to your local auto-parts store they could recommend something for you. It's basically a really really thick glue-like substance that you put into your transmission.
If I am thinking about your problem correctly then that might do the trick. If not then your tranny may just need to be replaced.
