    Does anyone know what the GM part # for the coupler sleeve that connects the output shaft of a TH350 to the input shaft of a NP205. My GM dealer can not come up with a #. Thanks!

    I have a 700R4 and NP205 using the TH350 adapter and was wondering how you broke the orginal sleeve. Just for my own information, Thanks

    I didn't break mine, I purchased a used transfer case and the sleeve that came with it had very badly pitted splines so I wanted to replace it.
