Mazda is in the process of integrating new engines with Dual Clutch Transmission (DCT) technology.

The source of this information is uncertain, however, it has been noted that the enthusiasm around the new CX-70/CX-90 platform, which incorporates novel longitudinal 6-cylinder engines, may be dampened due to the absence of a standard torque converting automatic gearbox for these vehicles. Instead, it is probable that the system will consist of an 8-speed wet dual or multi clutch configuration. If such is the case, this particular issue will be a decisive factor that will cause me to terminate the agreement. One may express admiration for the advantages of swift gear changing, proficient dual-clutch transmissions (DCTs), and their implementation in sports vehicles; yet, it is arguable that this technology may not be optimally suited for the average driver. One may consider transitioning to the Hyundai forum in order to peruse accounts of adverse experiences pertaining to the recently introduced Santa Fe model, which has a twin clutch configuration, so enabling an examination of the notable frequency at which these gearboxes are encountering malfunctions. Due to the absence of a Mazda dealership in our vicinity, I had created a purchase strategy whereby I intended to get the CX-70 model from a dealership located 75 miles away. I am unable to take the chance of encountering issues and doing extensive travel for recalls and repairs. Consequently, I will be compelled to explore other purchasing options in 2023. Unfortunately, I had believed that the CX-70 would be an ideal choice for our needs.

I am inclined to question the veracity of the source. According to the information provided in several CX-60 YouTube videos, it has been indicated that the CX-70 model would include identical engine options, including an 8-speed torque converter gearbox. I would be inclined to purchase a CX-60 in its current form and find it perplexing as to why Mazda has chosen not to introduce this model in the United States.

Moreover, it would be incongruous with Mazda's brand identity to provide many automatic gearbox options. It is noteworthy to observe the prevalence of the archaic 6-speed automatic transmission in a significant portion of their current car lineup. The Mazda UK website has the CX-60 model in its inventory, specifying that it is equipped with an 8-speed automatic gearbox. It is reasonable to anticipate the inclusion of this feature, at minimum, in the next CX-70 and CX-90 models, and perhaps in any non-phased out cars. However, it should be noted that this replacement of the existing 6-speed transmission may be limited to vehicles equipped with a longitudinal engine arrangement.

The CX60 configuration, equipped with a 4-cylinder engine, is paired with an 8-speed torque converter gearbox. The vehicle is equipped with a 3.0 litre inline 6 cylinder engine that runs on either gasoline or diesel fuel. This engine is paired with an 8-speed gearbox known as the non-torque converting multi-clutch transmission, sometimes referred to as a DCT. This indicates that the Dual Clutch Transmission (DCT) is intended for deployment in the North American and United States market specifically for the CX-70 and CX-90 models. Please engage in independent reading.

The implementation of DCT would also be a decisive factor for me. The potential for individuals to alter their perspectives remains a possibility, hence it would not be unexpected if the final production cars ultimately have conventional transmission systems. Despite the article being dated in March, it nevertheless made reference to the Mazda 6, a car that I had a strong desire for, as an approaching release. During that period, I became aware of the discontinuation of the Mazda 6.

[craigstomer]

No Mazda 6 is available. I am perplexed as to why Mazda has chosen to use a Dual Clutch Transmission (DCT). Torque converting transmissions are somewhat less intricate and provide a smoother operation in comparison to their more sophisticated counterparts. It is acknowledged that there may be a marginal increase in efficiency and a rapid ability to shift gears; nonetheless, it is important to note that this vehicle does not possess the characteristics often associated with a sports car. There is a cost associated with it. Dual-clutch transmissions (DCTs) exhibit suboptimal performance in sluggish traffic, prove to be very challenging in bumper-to-bumper traffic scenarios, and demonstrate inadequate traction in slippery situations characterized by the presence of snow. Moreover, it should be noted that the clutches experience wear and tear, while the transmissions require more regular maintenance. This Mazda gearbox is a recently produced model that is susceptible to issues often seen in other dual-clutch transmission (DCT) automobiles, making it imperative to be avoided at all costs. The perceived inconvenience associated with this particular car, which I would classify as suitable for family use, makes it unappealing. I am inclined to consider opting for a recently developed engine due to my confidence in Mazda's engineering capabilities. However, I have reservations about the implementation of a Dual Clutch Transmission (DCT). The individual exhibits a lack of willingness to undertake such a substantial level of danger. I am eagerly anticipating the release of the official specifications pertaining to the automobiles manufactured by Mazda. The release of detailed information on these vehicles has been notably sluggish, despite the many discussions within the industry that have persisted for a considerable period of time.

[shamaspoor]

My preferred option would be a manual, but, that is not feasible. I will go for a conventional automatic transmission due to need. I prefer not to go for cars equipped with Dual Clutch Transmissions (DCTs) or Continuously Variable Transmissions (CVTs) since I tend to purchase automobiles with the intention of retaining them for a decade.

The Mazda CX90 and CX70 both lack a conventional torque converter. It would seem that the wet DCT was chosen as the alternative. This eliminates the CX70 off my list of possible purchases for good. It's unfortunate, but given what I know about these gearboxes, I just cannot justify taking the 1.5-hour drive to the closest dealership. I had no problem taking a chance on a brand new six-cylinder engine in its first year on the market, but I would never put up with a wet multi-clutch gearbox. Well, I guess I'll wait to see what other manufacturers offer and make a call in the next couple of months.

[shamaspoor]

No, it's not a DCT and it's not a torque converter. Am I correct in assuming that a torque converter is unnecessary for Hybrids and Mild Hybrids? I bought a BMW 330e since I just couldn't wait for the CX70 and they had already discontinued production of the X3 30e. I don't think my vehicle has a torque converter either. What is it, then?

In this analysis, we discuss the transmission in detail: Check out this review of the 2024 Mazda CX-90 on YouTube (starting at around 16:00 and again at 32:00 for the Turbo S and PHEV models).
The special qualities of this broadcast are also highlighted in the review: (Around 2:00) 2024 Mazda CX-90 | First Drive on YouTube.
Another review claimed, while I can't verify its veracity, that the gearbox operates like a manual but is shifted by an electronic motor. I will include a link to that review if I am able to track it down again.
