Its a NP 246. And no I dont wheel it hard is the part. I very rarely need to run it hard when wheeling....but that aside it does it when I have to start running on the highway for any amount of time. I dont use the truck for trips but have had to every once in awhile and thats when I start noticing that its dripping atf and then just keeps getting worse, and clearly the 4:56 gears need to go for one.

Drive line angle is fine, personally think the rear could be lengthen'd maybe an inch. It stays in 2Hi unless I absolutely need 4wd. I pulled the tcase the other day and its actually the adaptor thats shattered. But last time I had a shop look at it they had said that the case half was cracked as well and needed a bearing and the chain replaced....I split the case halfs and have yet to find a crack although agree that it needs a rebuild. I am going to try and fab a braket to help stabalize the rear of the case since the adaptor is what holds the weight of the case and mounts the rear of the trans. Basically thinking I need a stronger adaptor from the OEM cast aluminum. I called Advanced Adaptors, and they said that they didnt have ANYTHING!!! for my truck to fit a 4L60E to a 246. So thats pretty much where Im at with it...any help or suggestions are greatly appreciated. Im tired of paying someone else to just fix the broken part and not figure out why its braking...so Im just gunna do it myself. This is the third time!!!
