Has any one heard of a NP 210 transmission being used in a M37 ? I seen one on E-Bay and the seller states its for a M37. I only know of two. The 88950 and NP420, unless Its for the Canadian Model ?????

Doesn't look like the NP210, wern't they used in Ferd's?

Looks like the early M37 transmission to me.

That is the early M37 trans. The top cover, rear bearing retainer, and oil fill plug are a dead give away. He just has his model# listing incorrect.

Charles,
What was the first model? The second model transmission was a NP 420, correct?

I think it was the 88950, no sure, I may be off a digit or 2 on that #. We always refer to it as the early trans around here.

New Process 88950 is correct. It also had an early and late version which primarily concerned filler plug location height.

Thanks for the replies and the info. I had found that number, but didn't think it correct as all New Process units I have seen are NP-### (3 digits). Anyone have any pics or is there a 88950 on the side of the case?

Easy way to tell if it is the early unit or the later NP420 is this. The gear shift stub lever on the early one can not be removed from outside the tower on the top cover. The 420 has a retainer that can be removed allowing the stub and ball assembly to come out from outside. The early will have the ball retainer pin visible from the outside of the tower on the right side only; the 420 will have the pins on both sides of the tower.

The rear main shaft bearing retainer on the early series has a handle like extension that is part of the casting that protrudes toward the left side; its purpose is to keep the reverse fork pin from backing out of the case. The 420 does not have the protruding handle or the reverse fork pin.

The oil fill / check plug is on the left side near the rear on the early case. The 420 fill plug is on the right side of the case near the front. As was mentioned, the early could possibly have the fill plug in a high or low position on the case. Most that we see are the lower configuration, which has a demple in the case directly above the fill plug. The earliest of the early series has the plug higher on the case, on those the demple will be directly below the plug.

Charles,
Based on your description, I have an early 88950 version. It is the later first version as the fill is low with the dimple above it. This is my spare. I still need to check my truck and see what is in it.
