hi there. i have a '93 mazda mx6, with 105k miles, automatic transmission, and the works. Had it for a month. And i got this problem with my tranny. everytime i start it up, it starts to shake erratically. i dunno why. and also, whenever i floor it, it doesn't have that oomph like it used to have. I dunno what the problem might be. I hope all of you can help me out on this. Is this something inexpensive to fix? Or do I have to buy a brand new ATX for my car? Let me know. Thanks
