dsapern Posted June 9, 2014 Report Share Posted June 9, 2014 I need help identifying my transmission. The casting number on the case says that it's a Warner. This can't be because of the NP logo right? The case casting number is C-38661, and the top casting number is C-39871. It has two different production dates...50' and 51'. Also there is a large 3" "S" stamped on the top. Any help would be greatly appreciated. I tried to download the pictures but the file sizes were too large.

Paul Beard Posted June 10, 2014 Report Share Posted June 10, 2014 Possibly a New Process. Quote Link to comment Share on other sites More sharing options...
dsapern Posted June 10, 2014 Author Report Share Posted June 10, 2014 Paul, Any ideas what type of New Process. I do know it's a NP 4 speed spur gear...is that all the farther I can go with the model type? I didn't know it there was a model number ex. NP420, NP435, etc. Quote Link to comment Share on other sites More sharing options...
brianjr660 Posted January 27, 2021 Report Share Posted January 27, 2021 hey bud, new here, just found this site. Wondering if you ever found out what trans you have there. I have the exact same one here too. Ive been tryin to figure out what tans this is for awhile. My pto is on pass side too. I have same cast numbers you have too. My case is dated 5.29.50 and my top is dated 5.1.50 or 5.7.50 hard to tell. Mine has that X cast into the pass side too. My case is cast with the C-38661 with a "A 8" stamped below that. I only have satelite internet, so cant upload pics, as I live in the hollar boonies. Also, can you take the shifter handle out? I cannot, the shifter handle has to be fed back through the top cap. Thought I narrowed it down awhile back to a np420, but nope, not it. I am wanting to buy a rebuild kit, but cant. Maybe you had better luck. ?

Or just tear it down and get number off each bearing. Good luck Quote Link to comment Share on other sites More sharing options...
