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.

#51 of 58 slipping clutch? by jveaston

Oct 08, 2009 (7:01 am)

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
 
thanks!

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?

#53 of 58 Transmission Control Module by star_rider

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.

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?

#56 of 58 2008 Icy-Blue Grand Touring Automatic; Questions! by vitara4me

Dec 30, 2009 (5:03 pm)

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

#58 of 58 Noice problems driveshaft by mx5mazda

Nov 24, 2011 (1:30 pm)

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 ?!??!
