Gear or hydro? I have a 633 I need to clean up, but not sure I have time to split the case and inspect everything. It will be out of the unit and I plan to drain oil, pour in a few qts of diesel and slosh it around, give it time to soak good and drain.

Gear. Also need to find axle seals. Sears has them but $22 a piece

Diesel fuel or Kerosene works decent for flushing.   Gasoline works better for breaking up the sludge but you'll have to flush with Kero or Diesel afterwards to remove the gas.

 

I had the shifter out to replace the seal on the shifter so I drained the water and disgusting brown muck out of the tranny and dumped almost a gallon of K1 Kerosene in the shifter hole and jacked up the rear of the tractor,  Started it and put it in 1st gear and let it run for 10-15 minutes.  Just 1st gear and don't run it any faster than a idle.

 

Don't forget to replace the Shifter seal. That's the one that is letting all of the water into the tranny. I bet yours is either ripped or completely blown out. They all are. 

 

The shifter seal is only $4 + shipping.  All of the sears tractors with the Peerless 3 speed and Peerless 3 speed with Hi/Lo use the same seal.

When I bought my Sears and pulled the drain plug I thought , ut oh something is wrong. Come to find out the common milky sludge is from keeping the tractor outside in the rain. I found the seal on top and changed that right away. I used kerosene to flush my transmission with but when it came time for re-filling I decided to go with an outboard gear lube, it has additives in there that help the oil not to break down into milky sludge so easy when water is introduced . At least now I know if I get a little water in there between changes I got oil in it that was designed to get a little water in it.

GASP!!!! OMG you guys leave your tractors outside????? LOL I have a pole barn I built for mine and they don't see water unless it's bath day, which is few and far between unfortunately. When I had the trans stuck on my suburban I followed directions and used the gas method, then some diesel, and back to gear oil. Works great now without issues. A big thanks to the guys on this site for directing me to try it before ripping down. :thumbs:
