Can anyone give me details or pics of the fix for a 190 that is pushing the hyd oil to the transmission side of the case?

Some people use the same oil in the transmission and the hydraulic, you can drill a hole in the case between the two, to let the oil level off, or you can tear it apart to replace a 50 cent seal with about $5000 in labor cost.

I read somewhere on here about running a hose from the two drain plugs. I had a little problem finding the right connections, but I have them tied together so the two sides can equalize and everything is working fine. Thanks for the reply.

It could be one or two problems. One is the PTO shaft at the bottom between the torque tube and transmission housing has 2 oil seals, they could be leaking (shaft grooved where the seals ride and seal worn also). The other problem could be the main transmission pinion shaft has a bearing holder with 1 seal in it and that bearing holder also mates up with the power director housing that has 3 sealing rings that hold/direct the hydraulic fluid to either the low range or high range clutches. The sealing rings and or the bearing holder that they ride in could be worn and letting hydraulic fluid push past them past the seal and into the trans. Both fixes require splitting the tractor. Both fixes are easy but when you get into the power director if you want to do it right and replace it to new so it will last it will cost you around $5,000 (that's replacing power director housings, clutches, gears etc. the whole nine yards). How do I know, I'm rebuilding my 190XT.

I understand that a seal must be leaking. However, I read a post here that talked about running a hose from the drain plugs on each side allowing the fluid to equalize back into the hyd side. I did that and it is working fine.

that's not a fix, that's a band-aid

plus your going to be mixing 2 different weigh oils.

the hydr and the tranny use the same fluid

wrong
