Both NP241, NP261 have a VSS sensor, So no need for you to buy a 2wd unit. A 4wd unit & Adapter will fit both T-Cases.

We only use 2wd units when adapting a older T-case that doesn't have a Output VSS sensor.

All GM Output VSS sensors create the same 40 Pulses Per Revolution A/C Sine Wave Signal.

Perfect! That's what I needed to know, thank you.

So running a 5.3 / 2WD 4l80e mated with a NP208 (no vss) would allow everything to work properly in 4LO?
