Trans swap

[valboski]

If the mk3 and mk4 both use the W58 5speed trans but the mk4 also is offered with the option of the V16x 6speed wouldnt that mean I could put the V16x in my mk3?
In 5th gear at 60mph I'm at 3100rpm
I need another gear
Any knowledge on this idea?
Its parked for winter and would love to do this
If it's not possible then gm auto trans with overdrive and high stall converter

Sounds easy, but the nomenclature is what makes it confusing.

MK3 and MK4 use different designed W transmissions

Is this not the same question asked and answered here http://www.supramania.com/forums/showthread.php?215056-Transmission

The real problem with the V160 is that it mated to a 3.133 rear end on the MK-IV. You cannot get that ratio on the MK3, so you will have gear ratios that are way too low to be useful.
