Warning: While Tuff Torq do recommend changing the oil in its unit, some other tractor manufacturer provide a "sealed unit" and don稚 need to replace the oil in the transaxle.
Haha sorry about that, I'm a mechanic for small engines and I rebuild gear transmissions pretty often, I just did that to see if it would help and it did. Not really any reason for me doing it other than the fact it builds up a good bit of heat and heat breaks down oil pretty quickly, that's why your car requires oil changes every so often no matter how clean the oil looks. As far as how it's done there's a plug on the bottom of the transmission, (look under it's the cloesest to the ground) you simply take it out drain the oil oil out, flush it out with about a quart of new oil, and replace the drain plug. After that you fill it with about 2 and a 1/2 quarts of oil (if it has a resivoir like mine that comes up through the gas tank fill it to the cold fill line on it.) A. Start and run engine at SLOW idle.
B. While alternately depressing the forward and reverse pedals, engage and disengage the release wheel lever (freewheeling rod).
C. Continue this procedure until the rear wheels start to rotate. This step may take up to 10 minutes to perform.
D. Lower the machine to the ground.
E. With control pedals in neutral, push the machine forward and then rearward to turn the motor rotating group.
F. Start and run the engine at FAST idle.
G. Quickly depress and release the forward and reverse pedals until the machine moves without hesitation.
Note: Tuff Torq recommend changing the oil at 50 hours for the first time and then every 200 hours.
You should notice a less noisy transaxle and better response of the pedal.
Interesting fix, want to inform us exactly WHAT this procedure does to remedy the transmission problem?
"The dealer said the same thing to me...." which was? Open to interpretation, did the dealer tell you about the fix? Or what did the dealer say?
If it wasn't the dealer, who told you about the fix? Your post apparently means well but is somewhat garbled, and lacking details.
