Re: How do i read the tag on my np205
The gm Np205 only came 10 27 and 32 splines.
10 splines Sm465 manual trans. 27 splines auto Th350. Thanks

Re: How do i read the tag on my np205
The 27 spline from behind a th350 is the correct spline count for the 4l60e, but the 4l60e out put shaft is too long. So you either need a spacer to accommodate the extra shaft length or you need to replace the out-put shaft with a shorter shaft from Advanced Adapters. You will also need the adapter from a NP205 / th350 set-up.
