I was driving around tonight and I noticed that entering 6th gear it is starting to grind . And i thiought only at a higher RPM / speed 5000 rpm 125 kph

Then i started to notice that even entering 6th at 60 kph it does it also.

I will be taking the car in soon to have it checked out and ill let you know.

 

How many kms on it?

 

5th and 6th gear grinding on Series II RX-8s is a known "issue"--one that I experienced myself:

Power Rangers says "it's dealer time"

 

oh its there right now its been there for 2 days now and looks like it will be there all weekend and up till tuesday at the earlyest

 

update
mazda canada does not talk to mazda usa and has never heard of this issue. however they are replacing anything that moves or touches 5th and 6th gear. i should get the car back thursday

 

yep...in the last week or so...ive been getting the grinding going into 6th also...its starting to become more frequent....i thought it was me at first...but its definitely something wrong....im gonna have to take it in....im gonna be there for the a/c too so might as well bring this up also...

 

I have an 04 mazda rx8, It has compression, spark and fuel. however, it wont start, it not fluided. However, the IMT valve is stuck open according to Advanced auto. I had it decarbed according to Mazda and it has 127,000 on the car. Would the IMT valve cause my car not to start?

 

^.....wrong place for this and we are answering in your other thread. This is for Series II(newer models).
