My poor 99 tibby is slowly dying..i am pretty sure the trans blew but it didnt make a noise? I was driving in reverse down my friends driveway and it popped out of reverse and went into drive..the reverse isnt working now and i can only drive my car up to 30 mph before it jumps out of gear..by the way my car is an automatic! Also theres a loud rattling noise and i cant figure out where its coming from! Any advice? is it worth getting a new trans or should i just give up and get another car?
