GM transfer case differences explained

[@ryanpeterson1051]

Well there’s also 2 speed t-cases/ low range t-case ( only available on Z71 models). And single speed t cases. That do not have a selectable low range.

Great info here, is there any info on using a 6l80 trans and transfer case in place of a 4l60?

Great lesson thanks

I would love to know since it seems that you know a lot of these t-cases, I would like to swap my single speed (6L) Silverado wt with a 2 speed transfer case … but I believe is very difficult to come around a 6speed application transfer case that have low range (because it was optional on the WT’s) but I thought maybe the 8speed application t-case could be used if I swap my dash switch plus the tcm (at least some folks with 08-13 trucks were able to do that swap of hardware(tcase/tcm/dash switch)

2020 Silverado wt, before people start saying to just buy a 2 speed (4low application truck) this truck is perfect for me except missing the 4lo

Great video. I have an Astro AWD with the NV136. I am going to be doing a LV3/6L80 swap in the future and would like to upgrade my transfer case but keep the AWD, would these be a good option?

They all still use the 24245110 adapter gasket that they’ve used since the 80’s.

I wonder about spline count? Does it have 32 spline like a th400 or a 4l80e? I have really been wanting to run a 6,8, or 10 speed transmission with a 32 spline np205 transfer case, and those lower gears in the transmissions would be awesome for rock crawling

[@swaptimeusa]

They are 32 spline
