I picked up a shit ton of power the next time i went to the dyno.

I had to replace the block, trans, and diff... diff failure escalated trans failure and lead to block failure.

Did you cry?...........I would have cried.......like a little child.

Dailying I'm willing to bet you're safe for quite some time.

anything else or harsh will cut down on your timeline. Diff is way sketchier than trans for sure.

Did it whine in 4th gear?

felt pretty good driving home 3 hours on this:


notice how long it took to take to redline... the throttle sticking was just the icing to the cake.

diff lost all fluid on the drive up. lolzzzzzzzzzzzzzzzzzzzzz.

That second video, it sounds like that veeeeeeeeery faintly with the top up, but the trans whine is differant...but if the was the diff noise the oh joy, no auto x for me this month :(

jhink92 10-04-2011 06:03 PM

Also it just started this weird thing where you stop and it idols at 1900 for a few seconds then drops back to around 1000 where it should. Y'all got this?

jhink92 10-23-2011 08:48 PM

Seriously guys tho so if my diff has just a little bit of whine to it how long would you say it has? Rough estimate

miata2fast 10-24-2011 08:06 AM

I broke two 1.6 diffs. Both failed completely 2 to 5 minutes after the whining started. I was driving normally during both occurances.

My 3.63 shines from 50-70mph on acceleration and has for the last three years. I presume its fine and would have failed by now if it were bad.

jhink92 10-24-2011 01:22 PM

word, thanks guys...i have roadside assistance so im just gonna keep driving it until something breaks :) come to think of it it does only do it around the 50-70 area

So what does this whine mean? Mine only does in the odd gears.

I have had a similar whine on my wife's 97 for over a year now. Is your whine just under decell or during accel too? With the 97 I get the worst whine between 50-60 under power and then it gets quieter above 70mph. It goes away completely when I get off the gas. I also had poly bushings on the diff for a while which made the whine 10 times worse.

If you do not hear any mechanical grinding sounds and had a pretty clean fluid change I don't think you have to worry about it failing any time soon. That is assuming you are not dumping the clutch at every light and assuming you are still running the stock 1.6 naturally aspirated. Having the backlash set too tight can cause whining too.

My 91 has so many whines and noises I quit worrying about it a while ago. Just make sure you pay attention to the noises and start worrying if they change or get worse.

If it makes that RC sounding noise in everything but the, then the trans is on its way out.

When I finally replaced it, it felt like a whole new car.

icantthink4155 10-25-2011 04:33 PM

Ive been beating on this transmission for 20K miles. And how ever many the previous owner put on it. Car shows just over 171K.

Vashthestampede 10-28-2011 08:28 AM

This video is with my old FM3 setup, but you can hear the whine pretty loud and clear. IIRC, the car has been making this noise since I bought it in '04. With the hardtop on and windows up it just cries like a baby.


Braineack 10-28-2011 09:04 AM

Thats exactly what mine sounded like. Notice how you don't hear it in 4th?

My car honestly felt like I gained 50hp when I finally swapped it for one with only 70K on it. No more whine, turbo spools faster and I had to add tons more fuel in boost (ie, actually making more power)

Well that's not good to hear! lol

Mine probably has around 70k miles on it now. When I bought the car it had 44k, so probably 20k miles since turbo'd.

Fix your damn camera mount!

That video nearly made me seasick from all the bouncing around.

mx5autoxer 10-28-2011 10:51 AM

Vash, I remember watching this video and thinking, "Oh good. My miata isn't the only one with a whiny trans." Mine sounds exactly like that. It hasn't always, but it has for at least a year. I think it started doing that a little while after I went FI.
