Isn't that the actual issue? How do you theorize it?





Doesn't the correct spring package prevent the clutch from applying "too soon"? So the clutch applying too soon is the cause of excessive overlap?

Of course, you realize that some overlap is necessary to prevent flare up. Thus, the issue becomes some overlap versus excessive overlap which, in mild cases, is often construed as a firm shift. Trying to choreograph the perfect overlap by manipulating parts is, indeed, the correct way to approach the issue; problem is, how do you know when you have the perfect combo?

In every case it's a "seat of the pants" judgement, what the driver perceives as a clean shift with no flare up or overlap when, in reality, excessive overlap might be present and not recognized as such because of other factors.

Bottom line is, the TF will always be inferior to some other makes because of this release/apply sequence. As to the restrictor orifice, correct parts that result in a perfect sequence won't account for eventual wear of rings and clutches that will interrupt the perfect sequence, so I see the changeable restrictor as a valid method not a Band-Aid.
