I have a 2wd 1996 s10 with a 4.3 and 4l60e. Im in the process of converting to 4wd. I know a mainshaft and adapter is necessary. The np 241 i just bought is almost exactly what i need except its 32 spline not 27. Will a 4l80e 4wd mainshaft work in my 4l60e no problem or do i need to sell this case and get a 27 spline. Any input would be great thanks.

Will a 4l80e 4wd mainshaft work in my 4l60e



No.

Ok thank you. Another stupid question can i swap the 32 spline to a 27 spline input shaft on my np241c? from whaat i understand its the same bearing and that way i can keep the rest 32 spline for strength.
