700r4 speedo?
That is after you change the program from the 17 tooth M6 vss to the 40 tooth A4 vss (pulses per minute in the programming)
The 4L60E and later 700R4 put out the same pulse per minute.
There are different type of 700 speed sensors though, but as long as you have the type with the 40 tooth reluctor wheel, it'll work just like a factory 4L60E.
