on one fine day i walked out to my car...start the car, put the gear in reverse...NO GO!!! :wtf...then i put the gear in Drive i moves! it can move forward but cant go in reverse! the next day, it wont move forward or reverse!!! ;( i checked the fluid level, it turns out ok...does anyone have an idea what could be wrong?

i've asked around different people and one said my planetaries gear set is failing...so assuming i need a new tranny, how much for a new tranny cost? and does anyone have an idea how much a shop would do the transplant 4?

thanx for ur time! :-)
