I haven't research this on the 6 in particular, but in other vehicles I've had an issue like this has had bad engine mounts. I've read the lower subframe mount on the 6 has a tendency to go bad, which would control/limit the engine from torquing. If it was bad enough it could allow too much movement of the engine and potentially pulling it out of gear. Something you might want to look into before replacing the trans for pop-out/worn fork.
I am with @hurddawg on this one.
Replace all 3 motor mounts. They are all likely worn, by putting only one new mount in, the movement from the other two worn mounts will prematurely destroy the single new mount.
Its not as hard as you may think.
I bought a 2004 Mazda 6 with a 3.0L and 5 speed manual transmission. After a good test drive I purchased the car. On the way home my dad was following me and noticed it was now smoking from the tailpipes. We got it home and checked the compression and at least 2or 3 of the 6 cylinders have low...
I'm having some problems with my wife's mazda 6 with the 3.0v6.
We just bought it and were told the timing chains were bad and the PO says he replaced plugs, sensors, solenoids, everything electrical so it had to be the chains. So I buy a timing kit and some gaskets, take everything apart...
I'm getting a miss. But it's not throwing any codes. So I'm pulling it apart and looking for issues.
This is a fuel line right? (Maybe the return?) It's been ages since I've had to work on this car. Does the clamp look right or is it broken? Looks like somethings missing.
