Replying to: stevedebi (Apr 24, 2008 11:16 am) Every point along the continuum is a ratio, but there are infinite possibilities within the minimum and maximum values. There are no defined points where the transmission "shifts" to a different ratio. The conventional definition of an AT "shift" is where the ratio changes. This happens continuously with the CVT.   Exactly . . . the CVT is (or at least can) continually adjust the gear ratio . . . thus, it is continually SHIFTING.   It's just that it's shifts are so small as to seem imperceptible, as compared to the larger shifts made by a normal automatic tranny.

Replying to: barnstormer64 (Apr 24, 2008 4:47 pm) No, a CVT does not shift. A CVT is actually a belt that moves up and down cones that get bigger and/or smaller depending on the direction the belt moves. There are NO shift points, simply an infinite range of gear ratios. To say the transmission shifts is incorrect.   - Chad Replies to this message: steve_ (Apr 25, 2008 7:14 am) freealfas (Apr 25, 2008 7:31 am) saabturboid (Apr 25, 2008 9:48 am) barnstormer64 (Apr 28, 2008 5:22 pm)

Replying to: saabturboid (Apr 25, 2008 7:03 am) I thought Ford used a chain for their CVT? Replies to this message: freealfas (Apr 25, 2008 7:31 am) saabturboid (Apr 25, 2008 9:48 am)

Replying to: steve_ (Apr 25, 2008 7:14 am) It is a steel mesh belt. A chain rides on sprockets while a belt is free to move independently.   - Chad

Replying to: saabturboid (Apr 25, 2008 7:03 am) No, a CVT does not shift.   Please define "shift".   I define "shift" as a change in gear ratio.   Thus, by definition, ANY transmission (including a CVT) "shifts".   In fact, if you didn't need to shift, you wouldn't NEED a transmission.

It is definitely a stainless steel belt.   And.. by definition, a CVT is incapable of "shifting" gears. It has none to "shift".
