Many web sites (Yahoo cars etc.) say the automatic version comes with a four speed transmission and over-drive. Am I missing something? To me, overdrive means some sort of torque converter so as to eliminate slipping at cruising speed, but my Mazda5 with auto just keeping on increase the RPMs as the speed goes higher. With cars with overdrives, once you hit cruising speed and the overdrive kicks in you notice it with a sudden drop in RPM. |

| Anyone tell me about the reliability of the 5? My wife really likes it as a replacement for her 03 CR-V. It seems like an excellent value. Is the leather worth it? Is there anyway to hook up an MP3 player to the stereo? | |

Replying to: idavidson (Jan 13, 2007 6:16 pm) Overdrive simply means that the trans output is turning faster than the engine. In the Mazda5's case, the 4th gear is an overdrive gear. It sounds like what you may be referring to is a lock-up torque converter which nearly every car sold today has. Once the vehicle reaches a certain speed, 40-50 mph, the torque converter locks to improve efficiency.

Replying to: maltb (Jan 29, 2007 10:21 am) When I bought my last car (also new) in 1998, the torque converters were refered to as "over-drive". For example, some of the older rental cars I have driven have an "over-drive" switch where the torque converter is disabled/enable. When I accelerated my Mazda5 Auto it quickly gets to 4th gear (as displayed), then revs up beyond 3000 but then drops down (presumably when the torque converter kicks in).

Replying to: idavidson (Jan 29, 2007 10:38 am) The torque converter has always been a means to allow variable slippage of the transmission's input shaft for getting underway, between shifts and when limited slippage will aid engine power to move the vehicle. Yes, your TQ will slip it's way into 4th gear and then lock when the power demand is palatable for the engine. It has no relation to overdrive and never has. |

Funny that the Mazda5 GT owner's manual doesn't state that it has a timing chain, versus timing belt. Do others agree (well, that's what I found out on the web) that it has a timing chain, and that a chain is better than a belt (even though noisier) since it lasts longer? Thanks

Replying to: zbx (Feb 27, 2007 1:24 pm) As far as noise goes, it's not that big of a deal compared to everything else that moves under the hood. a belt drive system is cheaper to make but car manufacturers likely sold the noise thing to public to get their buy-in. |
