Re: 4L80E & TH400 Tech.
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. |
