They are not terribly difficult to repair. That transmission should be the 4L60 Some things to add to the rebuild list: You should replace the separator plate between the valve body and the case. Upon inspection you will find that one or more of the check balls has beat itself into the plate - if not all the way through. This is a major cause of this transmission failing. Also note that it is a very tight fit to get the front band in. This usually becomes a wrestling match, but it is doable. The main point of failure of a torque converter is the lockup clutch inside. Even a failed converter will pull just fine until it comes time for it to lock up. If the transmission has metal flakes in it or has burned fluid in it, I would recommend that you shell out for a rebuilt converter. They are not all that expensive. should be under $200. The rear end of that trans is basically a THM350.
If you are intending to rebuild, you stand to save a lot of money. BUT, cleanliness is important, and you should disassemble and replace ALL O-rings and lip seals as well as the front and rear seals. That includes the low/reverse piston seal in the rear of the case.
Be sure to use the correct oil. The transmission will work fine with ANY oil that you put into it, but may not work for long if you put in the wrong oil.
I would also recommend purchasing a manual for it. ATSG publishes some excellent manuals for most transmissions. They run about $40, but they contain a wealth of information like power flow, locations of check balls, the function of each valve, and disassembly and assembly procedures.
So, there is my few cents' worth for what it is worth.

Today's Featured Article - New Hitches For Your Old Tractor - by Chris Pratt. For this article, we are going to make the irrational and unlikely assumption that you purchased an older tractor that is in tip top shape and needs no immediate repairs other than an oil change and a good bath. To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
