So my 09 is kicking out of 4ththe when I cruise in traffic for a bit. It's not everytime and usually when I speed up then slow down and speed up again. Its livable but just wondered if that was common or an indicator of a larger issues. Thanks

sounds like a new tranny is on its way.
the locker is not locking in the shifter.

I will see what the dealer says luckily its still under warenty

wazup_shorty

should be covered 5 years 60 000 miles at lease, may just be the srping holding back the syncro position in the tranny that is broken and not aplying presure, I dont think they would replace a whole transmission for this

So what are your opinions on installing my cat back before I get any warranty work done? Should I wait til after I bring the car in? I know that's been covered somewhere in the forum and that the law I believe states that it has to have a direct correlation of cause and effect but just wanted some feedback on this scenario. I don't think I will get it to the shop for a few weeks as the issue is not really persistent or that bad right now. My cat back, however, gets here today and waiting to install it would be torture.

After looking at the ease of putting the cat back on I think I am a go from installing. If the issue persist or gets worse I will just switch it out no longer than it should take. Thanks

My 2009 had the same problem, mine kept getting worse until I brought it in.

There was a thread/post about it but I can't seem to find it any longer, it may have been deleted during the S2 thread cleanups?

Anyway if you search miata.net NC forums for 4th gear popping out, a thread will come up with an adjustment procedure and even videos of the same thing happening on NC Miatas. It's some shift linkage only used on 3rd & 4th gears that needs to be adjusted.

I performed the adjustment procedure on mine but either I did it wrong or something was broken inside cause it didn't help mine. I ended up taking it to the dealer, and they did not give me a new transmission. They went in and changed some parts and made some adjustments. Got it back and told them to adjust it again because third gear was too "sloppy". After that it's "ok" now.

This is the NC thread is question..

Although the shift lever assembly is not the exact same in S2 RX-8 as the NC MX-5, the principal and adjustment is.

Get the dealer to check the Position of the Shifter as shown in this pic from NC forum.

The thread link above will show the dealer how to adjust gaps..

So dropped off the car last week. They have replaced some parts in the transmission so I will mention exactly what is was if I find out. Should get the car back tomorrow.

My 4th gear pops out on rare occasion when I'm applying just enough engine torque to maintain speed. I've thought about taking the car to the dealer for warranty repairs, but I'm scared of having to run back and forth a half dozen times until they fix all the problems they cause by taking the transmission apart to start with. Also, I have this sneaking suspicion that they're just going to blame my Redline gear oil and refuse to do the work under warranty.

Bladecutter

Then you might want to consider not mentioning the oil change to them.

Ok, so got it back today. They replaced:

some springs
fork
hub set
shifter rod
a few bolts

Not very helpful descriptions of the exact other nuts and bolts sorry...

I will say it is shifting much "cleaner" I guess you could say. I also could use to feel the shifter moving if I held it while in 4th gear but it stays solid as a rock now and seems to be fine. Overall I am happy and glad I took it in.

Thanks for the suggestions and replies.

Good lord. This just started happening to me today. Had no idea what the hell happened at first, but the thing kicks out of 4th any time I apply gas. I have to physically hold it in place, or just suck it up and shift into 5th early.

Looks like a trip to the dealer is in my future. This is the second time I've had to abuse the 5yr/60k warranty, since I had the synchros for 6th replaced.

Mine does it every once and awhile in 3rd just pop out, only happen under really hard acceleration.

ASH8

Can you guys plz give me a mileage update on your car trans...thanks.,

RXeckless

iTrader: (5)

Sure can!
2009 R3
60,000 kilometers or 37,000 miles

ASH8

Thanks M8!

What are your 'stick' changing points (yes I know it varies a lot) @ what RPM roughly.

Plz, I am not trying to PIN you down, just loookinn at an owner's profile...that is all.....

More likely to be a shifter alignment issue than a lockring issue. When I had my transmission serviced recently, the *real* shifter boot (not the cosmetic bit you can see from inside the cabin) was twisted and it was binding-up when I shifted into the even-numbered gears. 4th gear was popping out like crazy. I took it to the dealer and got it serviced, and it's fine again now. So it could be the lockring isn't actually getting pushed all the way into place to start with, and that's what's causing it to pop out.

Wow, it happen again this morning on the way to work, as well on Sunday.
This is the 4th or 5th time in the pass couple of months, first time it happened at the track just after exiting a corner and the tarmac had a lot of washboarding, so I'd say 7-9,000 rpm shift point and the same this morning. Very random, if I try to reproduce the problem I can't do it. At first I thought it was driver error but now I'm sure it isn't.

Had this problem in my '10 sport ~30k miles. Just got my car back from the dealer and here is a copy of the invoice. Car feels much better now.

"eazymmkayrx8"..

Many thanks for posting up the Parts and Part Number list for your 2010 Transmission repair, It makes it so much easier for me to investigate and also to help others as it lists exactly what parts were renewed...so you go to the top of my member rankings...

I wish more would give details like you...

Anyway, some other info..

All your parts are originals, meaning they have not been updated for ANY Series 2 at any model year and many are the same in the Miata/MX-5 P66M 6 speed Trans...So the renewed parts are identical to the damaged ones.

As a 'general rule' I can call this as a rare event, WHY?, well when and IF there are many Trans which do this Mazda will always investigate and usually always modify part and part number, plus production dates to show when they have re-engineered or modified the part(s).

As I said in this case all these renewed parts are unchanged for all S2's....

A little more history, the Counter Shaft Assembly which was renewed uses the exact same two Roller Bearings as used in the 1991 Mazda Navajo, B2300,B2500,B3000,B4000 Trucks and all NC Miata's....So 'load' wise I call the bearings 'rugged'.

Anyway, I trust the dealer performed the correct 3/4 Shifter alignment/adjustment, which they should have as they replaced the complete internal ''adjuster lever and bush''.

I think you will be OK now, out of the 20,000 P66M S2 manuals made world wide and the 100,000+ P66M NC Miata/MX-5 6 Speeds, the number of these same issues is pretty low.

I know I sound like a broken record, but these Transmissions like to be looked after when cold and like a good GL4 Gear Oil which is renewed much sooner than Mazda's recommendations.

Sorry, I can't answer 'why' your trans did what it did...

easymmkayrx8

Ash8, good to know it's not terribly common for this particular problem. I just bought the car and the problem didn't show up in the test drive. Luckily I have a company truck and work 14 hour days, so having the car at Mazda wasn't an inconvenience. However, I would have continued searching if I would have noticed it beforehand.

Karack

i wouldn't put too much stock into a dealer invoice, because a) the techs usually just replace items as a guess or find the root cause and b) make up a story to get paid for additional repairs which weren't performed.

while it may sound like a conspiracy theory i have seen it all in the field, if you open a tranny tech's tool box you usually can find enough brand new parts to build several transmissions with.

sorry for bumping this with the random commentary, just dealing with a similar situation at the moment and doing research.
