i have a 2004 rx-8 and i think the trans is going and i only have 34000 miles. when im cruzin in 4th at 50mph it just drops to 2nd by its self. that is not normal. and also how many times haveu guys had ur motor mounts replaced? ive done it once and i think they r broken again. tell me what u think. thanks

 

Yeah, You should Bee line it while you can still drive it to the dealer or repair shop.

 

^ what he said

 

Mine is in right now getting the tranny replaced...70,000 miles on my clock.

 

Unless you really treat your tranny bad it shouldn't go bad so soon. It sounds like a vacuum problem or something similar. As Silver_Surfer and kersh4w said, you should take it the dealer especially if its still under warranty. . .

Also, motor mounts typically last for around 50K or so depending on factors such as weather, etc. Do you hear any mechanical "thunk" sound? If so, then it might indeed be a mount that has degraded. BTW, what makes you think the mounts are bad?

 

hey guys, thanks. im taking my 8 in on monday to the local mazda dealer. i still have warranty, so im not paying one dime. lol. and my motor mounts ive had replaced during the winter. hey broke and it was about -13 degrees out and i started and drove it right away cuz i was running late for work. stuiped i know. lol. and also. if you guys know what i should do to my 8 as in performance?

 

^Performance depends on how deep your pockets are.

 

or how deep your parent's pockets are

 

^ what he said

 

well they are my pockets.. the parents hate the car... i bought the car my self.. soo i just want to be careful on how i spend my money because i want to get it right the first time.. ive been thinking about the Pettit SuperCharger and Charles hill Raditator.. so let me know if you guys know of anything else. thanks guys

 

Might not be your motor mounts. what felt like motor mounts for me ended up being an engine replacement.

Best wishes

 

Better to get that 8 fixed and trade it in for a manual one before even bothering to do performance mods. The Renesis is crippled in the AT model.

 

By the way, I do have low mileage auto trans for these cars, for anyone that is out of warranty needing one (Shameless plug ).

Paul.

 

As is any other car?

It doesn't cripple it...Sure it's not as fast as an MT, but by no means is it going to make mods do not perform just aswell as they would with an MT. They'll do just fine, but your transmission will hold you back a bit, but not CRIPPLE YOU.
