Swapping a 98 4l60e into a 94

Swapping a 98 4l60e into a 94
I have a 1994 C1500 2wd pickup with a bad 4l60e transmission. I have a good 4l60e from a 1998 C1500 2wd pickup. I'm wondering if it is possible to do this swap. The bellhousing pattern is the same, as is the overall length. The only differences that I see are the transmission mount location, the speed sensor connector, and the shift linkage. The transmission mount shouldn't be a problem because I can modify my crossmember to fit. The connector for the VSS is different, and I have been unable to find an adapter. Does anyone know if the electronics in the sensor are different, or if it is just the connector? I haven't taken the valve body off yet, but I'm almost certain that I can swap the shaft that the shift linkage connects to.
I've also read that some of the solenoids are different and that I just have to swap the solenoids and internal harness from the 94 to the 98. Is that true? If anyone can guide me as to what I have to do and what I need to buy, it would be greatly appreciated.
Thanks,
Andrew

the 98 is a PWM unit. The vehicle harness on the truck does not have a provision for the PWM function. I dont know for sure how the trans will react with out PWM. It may burn up or not activate the converter clutch.
