Does anyone have a jd420c transmission they would like to sell? I am looking for a 4 speed as the ring and pinion is shot in mine. Please let me know what you have and how much. The closer to Northern Ohio the better. I am also looking for part number m2375t which is the cover that goes in the back of the final drive on a 420. If anyone can help let me know. I have found a transmission in the upper pen. of Mich. which I may go get, but I thought I would see if anyone else had any leads closer.
Thanks,
Mike
Wanted JD 420c 4speed transmission
more info 420c
The serial number of the crawler I am working on is 119424.
The casting number on the side of the transmission is m4002t. Now I need a little education here. The 4 speed transmission I found has a casting number of m2980t, I think, hard to make out in the pictures. What year is this out of? My books don't reference this number. The shifter on top is different so I am assuming it is earlier, it looks similiar MC, as mine has the shifter guide and this doesn't. Would this transmission work for me? The guy I am dealing with also has a 5 speed transmission for a crawler, would it bolt in with no issues in my 4 speed machine? Is there any other parts I would need if I would buy the 5 speed? Which is better 4 or 5 speed?
Okay my last question for today,
Do the ring and pinions from all 420 4 & 5 speeds interchange?
Thanks in advance for the info.

I was thinking it would be cheaper to try to find a used transmission that was in good shape versus a ring and pinion. I can buy a used tranny for $400. I havent priced just a ring and pinion anywhere but if I have to disassemble the whole transmission and install new bearings, set up the rearend, and my time that is involved I did not think it would be worth it. I thought I would just buy a used one. Do you have a ring and pinion? What do you want for it?
Ring and pinion is not going to be much cheaper than the price you were quoted for a whole trans.
Keep in mind that the used trans you are getting may not be any different than your used trans was a few hours before it went bad. There is no easy way to do a trans, so why run the risk of doing it again. Whether you buy a used tranny, or put a ring and pinion in yours, either way the trans should be rebuilt.
