Mazda MX-5 Miata Transmission Problems

    squell noise in 4rth and 5th gears .stops when clutch is depressed. :)
  • Hi, I have a 1999 5 speed Mazda Miata and lately when I am changing gears it makes a grinding noise and "fights" me a little to get it in gear. This just started. Do I need to have the clutch replaced?
  • I have a 2000 Miata SE 6 speed. It sometimes makes a rather loud growling sound only when the clutch is engaged, even shifting to neutral or another gear will not stop it, but It stops when the clucth is let out. I don't know if it is the clutch or transmission?

    I Was backing up my sloped driveway and when I stopped on the level surface the car would only go into reverse something seems to jammed any clues of what is going on? So I Can save a tow Thanks you KSeguine
  • I just bought a 1991 Miata with 95000 miles on it. When the car is in neutral, it does not vibrate very much and idles at 750 rpms. But when you put it in any gear with the clutch pedal in, the rpms drop to 500 and it begins to vibrate more. When the clutch is out, there is not any vibration, and there is no vibration with the clutch pushed in and in neutral. Any ideas?
  • I have a 2002 LS with less than 29K miles on it. It frequently is either hard to upshift into 2nd or grinds a little when it goes in. Sometimes I get a lesser version of this when upshifting into 3rd. Other times it's as smooth as can be. It happens less at high RPM shifts. It never happens on downshifts. My mechanic says there's nothing wrong with my clutch or its hydraulics. My problems seems similar to those in posts #41 and#47. My wife's '93 Miata, with 100K miles still shifts perfectly smooth under any and all driving conditions. Her shifter stays rock solid when getting on and off the throttle in any gear, but mine moves a little fore-and-aft. My mechanic checked my engine mounts and said they're fine. Can anyone shed some light on this?
  • I bought a 2008GT used.I usually do my own oil changes and maintenance, but cannot find where to check or add ATF. Not even mentioned in the owner's handbook...any help?
  • Oops. I didn't mean to refer to posting #47. #44 was the other one that sounded a lot like my problem.
  • hey everybody
    I have a 99 5 spd miata and we got it used with about 40,000 gentle miles on it and no significant parts replaced
    lately when I try to get up to a relatively higher speed (45ish), the rpms spin up to 5000 and stay there. the car will still hold the speed and I can accelerate but it feels like the car is working wayyyy to hard to do so, like it's super underpowered or something.

    is this a sign of a slipped clutch? i havent done the parking break- 4th gear stall test yet but I thought I'd ask you guys and see if anybody had any input

    I had a slipping clutch on a Datsun ages ago and the symptom that stood out was that the revs would climb while in gear even though speeds would not climb. Does that happen?
  • I have a 97' miata "M series". I recently experienced a problem where the transmission (automatic) would shift through the gears normally but would not go into that last over drive gear.Causing the car to run at high RPMs.The "Hold" light is flashing and the check engine code tells me to check the shift solinoids.After extinsive checks what I found out is that that there is nothing wrong with the transmission or the solinoids.
    The problem is that the Transmission Control Module (TCM) is not sending a signal to the transmission to make that final shift.Well the BIGGER problem is that Mazda no longer makes a TCM for this model,and I can't find any Electric shops in my area that can rebuild it.
    If anyone can tell me where I can get my hands on a TCM for a 97' miata I sure would appreciate it. :sick:

    Junk Yard, perhaps?

    When I had my 93 I'd visit the junk yard in CT near my in-laws' place once a year. I'd always find something I could use - a clip here, a latch there. Small stuff like that.
  • I'm having the same exact problem. Have you found the TCM yet, or another solution?
  • Greetings. I have 2008 Icy-Blue GT with a cloth top and 6-speed automatic. I noticed that on a cold day, the 1-2 is really sluggish and feels like it slips a little. Once warn, the tranny shifts normally.

    My question is this: Is there a way to modify the automatic in the 08 Miata to have firmer/ stronger shifts? I understand that the trans is computer controlled, so maybe there is a module or chip that can improve shift quality? Perhaps a different fluid type?

    Last question: Who makes the Miata automatic tranny? Is a Mazda unit, or one of the other Japanese sub-contractors? (Asian-Warner, Jatco, etc....)

    By the way, this is my first Miata and I LOVE IT!! My last Mazda was an RX3 Rotory sedan, and before that, I had a Mazda Cosmo Coupe (also a Rotory).

    Thanks!! ARG

    Hi ARG, it's been a while since your post. However, I hope you can respond to my post. I'm looking at a 2009 Miata with low mileage and a 6-sp AT. I prefer manual. I'm wondering what's your experience with your 2008 Miata6-sp AT. How does it compare to a manual. Thanks. -Hieu
  • hi, i experience an enoying noice comming from the driveshaft or gearbox area. I could not exactly locate the source of it. i have a mazda mx5, '92 miata U9, manual shift. what could be the problem. the gearbox shifts smoothly, oil on the box and driveshaft are checked. Any ideas before i have to exchange the complete gearbox and driveshaft ?! The noice is also there without engine running and gearbox in free.. so i think its source can be found in the reardriveshaft upto the gearbox.. ?! While driving around 20 - 40 km hour the noice is very well hearable and slightly gets worse while pushing the shiftstick towards 3rd gear without using the clutch. any idea ?!??!
