A/T shifting.....

Are there any company's out there planning on making or in process of making something to improve the shift characteristics of the A/T 8's?

IMO, our tranny's should not be shifting this sluggish for the type of car that it is.

Probably because 1) front-drive transaxle isn't easily reconfigured for a rear wheel drive application, and 2) it probably can't stand the high RPMs of the Renesis.

true and also this was the only one that would fit that was available to them at the time they needed to get everything ready for production. they just ran out of developement time and money for what they really want to do. you'll see that for the 2006 US model year.

The A/T is limited at 7000 RPM (I think)... What is the red line for the 6?

We've discussed this often - as mentioned, that's a transverse gearbox with integrated differential. Not exactly suitable for a RWD RX-8, is it?

Mazda is developing a 5 speed auto trans that can handle the 9000 rpm redline of the high-power Renesis - they didn't have the development budget or manpower to have it ready for the RX-8 introduction, so that's why the AT so far is the old 4 speed that is rev-limited to 7500 rpm. The new 5 spd AT will be available on the 2006 RX-8, along with a new 6 speed SMG (semi-manual) gearbox.

Regards,
Gordon

Don't forget, however, the MR2 Spyder has SMT at around $26k nowadays.. Didn't like the car much myself.. too small for me to fit.. but I did find the SMT fun to play with.. Shame they didn't go the whole 10 yards and make it fully auto if needed.. but anyhow.. back to our normal programming...

I am trying to get in touch with LEVELTEN.COM<-- I think thats the web site. In a back issue of SS mag, one of the editors has a IS 400 or 330, the small one, that has 400+ hp or something like that. He has Level-10 on his sproty/AT. He said this way he wont melt the gears in his car.

*chuckle* Of course not.. but then you are not paying BMW or Ferrari's prices either..... For the money it's not a bad system... just not as good as "the real thing!"

Nope, not yet. I was told by an 'inside' source that is reliable, but I can't and won't name names. It probably won't be announced for almost a year (until the 2006 models are near release).

Gordon

Now that Ivehad my automatic for 15000 miles the lackof response from the transmission has become very noticeable. I haventbeen babying my car at all but I havent been ragging it out either. Lately its always taking up to 4 seconds for it to shift from 4th to 2nd gear whileIm cruising on the highway. For instance when Im in 4th gear at 45 - 50 then go into tiptronic mode and drop down to 2nd gear the time it takes for the car to go down 2 gears seems to have doubled.

Another strange occurrence that oftenly happens now w/my automatic is if Im calmly cruising for a bit andthen I all of a sudden floor the pedal the entire car completely lurches forward right after the gear changes and the power kicks in violently instead of smoothly like it used to. It feels likethe car is on a wild slingshot all of a sudden and Iknow this type of behavior was not happening 6 months ago. I thinkits time for me to get my transmission checked out
