It’ll physically fit, yes. The later vt onwards style converter supposedly had a better lockup clutch incorporating Kevlar. They used a gradual lockup (pwm) that can be adjusted in the tune. Pwm can also be disabled by fitting certain shift kits. Even th700 converters fit the 4l60e’s provided the spline count is the same.
Fairly sure that it was only in the US that they had the different input shaft spline counts though.

The extra PWM solenoid was used from late VR onward for the gradual converter lock up. Unfortunately it does wear out the lock up clutch with time. Can get rid of it in the tune without needing a shift kit. With the gradual lock up removed the converter lock up feels like another gear, bloody marvellous ;)
