Yes everything is still working great a year and a half later ! Im runnin a 4L60e and the original '87 NP208. I used a speed sensor out of a 99-06 4x4 silverado transfer case , drilled and mounted it in the adapter at the correct location, and used a Dewalt 4 inch grinder wheel retainer nut to hold it in place believe it or not lol. I did put a little JB weld on it just for extra insurance, but it worked.Just gotta find something or make something work lol.
I know theres better ways of doin it but this worked for me, you can get a NP241 tailhousing/speed sensor and tone ring to work on a NP208 ive heard, but theyre hard to find so i made my own.
I had a 40 tooth reluctor wheel layin around from a 2wd 4L60e that pressed right onto my 4x4 shaft and everything worked great. Also be sure to grab a 6 bolt 4l60e adapter for the NP208 from a 99+ chevy truck. I grabbed one from local junkyard.
Good luck on your swap ask any questions you want ! I look forward to seein some pix of your swap
