I just read through this thread and find the postings very interesting and you know what is staring me in the face? 99% of the time I don't agree with Ric or Carscw, but MyGuy99 this time they are right and you have to look at the big picture, not at just one part. I don't know what you're background is, but I do know that what you are trying to pass on as fact, is misinformation to the DYI members on this forum. Sealed means Sealed. I have torn apart and rebuilt more transmissions, transaxles, Hydrostats and rear ends than 95% of the members on this forum, so I feel I do know a little more than most members. Sealed units mean that these units are not designed to be serviced. Can someone service them? Yes, but not all parts may be available. Have I serviced sealed units? Yes, but have had to either scavenged parts from other units or had to match parts from serviceable units. This takes a lot of time and knowledge to do it this way. Have I been 100% successful, NO. Do I recommend repairing a sealed unit, almost never. Most of the time it is cheaper to replace the sealed unit than it is to repair it, but at times the replacement is no longer available and the customer wants to keep this machine. At my labor rate, this can get very pricey. I just recommend that before you pass on info on this forum, please make sure that, the info is directly related to an exact problem or is broad enough to apply to many different units. Vague or misinformation can be both expensive and dangerous to many who read it. Most members do not have the skills to understand or repair drive trains, and should not be pointed in that direction. My signature says what you can do with this post and I recommend to all others who look to this thread for answers to read each post very carefully.
