Quote: I can't tell you any ET gain or loss, but I just wanted to say that Griner makes a fully manual valvebody for the 500/518s. You actually make the 3rd to OD shift with the shifter.
This is exactly what I want.
It eludes me as to how you would be able to shift into overdrive with a shifter though. Overdrive is activated with a solenoid. Is it a button on the shifter?
As far as I know, the only way to do this and still have overdrive and lockup is with vac/pressure switches.
Details???
Maybe it's a custom made valve body and not a modified stock one ?
And where are the apples to oranges result of the swap ???
