had to get my transmission replaced at 15500 miles you might have a problem i think allot of my problem had to do with mis shifts .Originally the problem just seems to be it wouldn't stay in 2nd under any kind of load. it would go into any gear just fine though . Wound up being bad bearings in 5th and 6th gears 2nd and third needed to be replaced and the syncro's also . When they finally got it all together they decided to go ahead and replace the whole thing . Got it back the next day after the new trans came in and the shifter cables were bad . Made it real real hard to put in gear you literally had to force it . The whole process took the dealer a total of 29 days in Va you qualify for the lemon law in 30....... I purchased the 100,000 mile extended warranty and got Mazda to do my Cai I asked about the motor mount and they said that wouldn't void the warranty but I wouldn't try going in there with anything else on there not mazdaspeed branded. Isn't basic like 36,000 anyway you should be ok I believe.
