NP440 MY6 help

[birdistheword]

I did this swap in my 69 C10 probably like seven years ago. I found a complete one with shifter. I rebuilt it and it was way more fun to drive compared to the SM465. The only issue I had was when shifting out of reverse it would sometimes bring 1-2 with it. I should've rebuilt the shifter or installed bronze bushings in the shifter linkage. I thought it was odd they took ATF instead of the normal 80w90, but liked the fact the gear ratios were nearly identical to a 700R4.
