Re: 4L80E/Transfercase
I just quickly checked the silverado ss.. I guess the '06 SS have the 4l85e in them.. though not sure if I read somewhere if thats just the 2 wheel version or in both the awd and 2wheel.

Yep. 2wd. If there was an AWD case we would not have made the adaptor and shaft and all of that for the BW.

Re: 4L80E/Transfercase
One nice thing about the BW4472 is that we've run it down into the 8s without any issues. Do you know how far they've pushed the NVG149?
Sweet! How much and where can I get it? There was a LOT of talk about this on the SS board and nothing ever happened with it. Was kinda the mysterious ghost input gear that no one could get. I think the guy's name was Jay that brought it up. Thread went on forever and then just died.Sherlock said:

Re: 4L80E/Transfercase
There are guys running 8's all day long with the 27 spline shaft. Some testing has been done. Capacity is well over 1000 foot pounds of torque. The 700r4 failures are not from the shaft diameter. It's from holes drilled all through it for lubrication. The 80e design doesn't have this setback. I'm not saying the NVG149 32 spline input gear is a bad thing. They machine out the inside of the input shaft to accept the 32 spline. So the wall gets thinned. Not a terrible thing. They have customers running them without issue. We've just had a LOT of luck with the 4472 and a lot of luck with the 27 spline setup. Several years now of trouble free abuse.Just don't let a 27 spline shaft deter you.

Re: 4L80E/Transfercase
I googled the hummer, and the one with the 6.5 Turbo diesel has a NP 242 with a 4L80 E. I can't remember if they were full time in the hummer. But, the one for the Jeeps had full time capability. And has a 48/52 torque split front rear. The biggest thing would be the physical dimensions and prop shaft side (drivers/passengers side).
I hope I helped some.

Re: 4L80E/Transfercase
That chain in the 242 is 1/3 the size of the chain in the 4472. It would be a step down.

Re: 4L80E/Transfercase
Hey George....
Any idea as to how the chain in the NV246 compares to those 2?
