Not sure where I came across this information but after having been extremely excited about the new CX-70/ CX-90 platform including the new logitudinal 6 cyl engines, I heard that they will not be mated to a conventional torque converting automatic transmission. Instead it will likely be an 8-speed wet dual or multi clutch system. If so, this will be a deal breaker for me. You can sing all the praises you want regarding fast shifting, efficient DCT's and sports cars that utilize this system but for the typical driver I don't think this system works very well. Simply switch over to the Hyundai forum to read about the horror stories regarding the new Santa Fe which uses the set dual clutch setup to see how these transmissions are failing at an alarming rate. Since we do not have a local Mazda dealer, I had planned on purchasing the CX-70 from one 75 miles away. I simply can't risk having problems, and traveling that distance for recalls and repairs so will need to find something else buy in 2023. Darn, because I thought the CX-70 would be perfect for us.

I'm hoping the source is wrong. We were told on most of the CX-60 YouTube videos, that the CX-70 will have the same powertrains, and that includes an 8 speed torque converter transmission. I'd be happy to buy a CX-60 as is and can't understand why Mazda would not bring this to the US.

Besides, it would be very un-Mazda-like to have more than 1 automatic transmission offering anyway. Look how many of their vehicles today use the antiquated 6 speed automatic. They list the CX-60 on the Mazda UK site as having an 8 speed automatic transmission. I would expect to see it at the very least, on the upcoming CX-70 and CX-90 perhaps even on any vehicle that is not being phased out, (unless it is specific to vehicles with the longitudinal engine configuration) replacing the current 6 speed.

The 4 cylinder CX60 configuration gets a torque converting 8-speed transmission. The 3.0 litre inline 6 cylinder gas/deisel gets the new 8-speed NON torque converting multi clutch (or DCT) transmission. This means that the DCT is slated for the North America / US market for the CX-70 and CX-90. Read for yourself.

DCT would be a deal breaker for me too. They can change their minds at any time - so I won't be surprised though, if the actual production vehicles get the traditional transmission. The date of the article is March and yet the Mazda 6 (which is what I really wanted) was still being mentioned as an upcoming vehicle. I first heard that the Mazda 6 had been axed around that time too.

Yep, no Mazda 6. I simply don't understand why Mazda would go with a DCT. They are more complex than torque converting ones and simply don't provide the smoothness of conventional automatics. I understand they may be slightly more efficient and can quickly change gears but this is not a sports car. It comes at a price. DCT's are jerky in slow traffic, are a nightmare in bumper to bumper traffic, do poorly in slippery conditions where there is snow. On top of that the clutches wear out and the transmissions need more frequent maintenance. Add that this is a newly developed Mazda transmission subject to problems that plague other DCT vehicles, I would have to avoid at all cost. Simply not worth the hassle with what I would consider a family vehicle. I could go with a newly designed engine because I trust Mazda with this but a DCT? Simply not willing to take that big a risk. I can't wait for the official specs on these vehicles from Mazda. They have been glacially slow on any details yet the industry has been talking up these vehicles what seems like forever now.

First choice for me would be a manual, but that ain’t happening. I’ll take a traditional automatic because I have to. Absolutely no DCT’s or CVT’s for me because I like to buy my vehicles and keep them 10 years.

An interesting sketch here:
2024 Mazda CX-90 ushers in three-row RWD platform with turbo inline-6 (motorauthority.com)

Mitsuru Wakiie, the executive in charge of the CX-90 program, told Motor Authority the two powertrains' torque figures being the same isn't a coincidence. The output is nearing the new 8-speed automatic’s power limit. The 8-speed automatic transmission is a clean-sheet in-house design featuring two wet clutches and no torque converter, the latter replaced by the electric motor. Behind the engine but inside the transmission casing sits the electric motor, then a wet clutch followed by the 8-speed automatic transmission, then another wet clutch, which hooks it all to the driveshaft.

Yep, no traditional torque converter for the Mazda CX90 and that means also for CX70. Looks like they decided to throw in the wet DCT instead. This is a deal breaker for me and so I will no longer be considering the CX70. It's a shame but having the nearest dealership be 1.5 hrs away I simply cannot in good conscience knowing what I know about about these transmissions take the chance. I was willing to gamble with a new 1st year out new 6 cyl engine but seriously not with a wet multi clutch transmission. Oh well I get to now see what other manufacturers have and will make some decision in the coming 2 or 3 months.
