having some issues with the GT245 hydro. It's a Tuff Torq K71B. Fluid levels are good, use JD fluids.

The tranny has a whine that gets louder as you go faster. It seems to have good power going forward. Today it went up a good hill and spun the tire, never stopping, just pulling itself up.

However, in reverse; it will sometimes slip. Make a clicking sound, or a ticking sound. If you move slightly forward, then back into reverse it will usually work just fine. When backing up long distances, you can notice it occasionally slips also.

What do you think it could be? Could it be the pulley on the input shaft is getting stripped? Any other ideas?

Thanks

I'm not familiar with that hydro unit. I would check the axles to make sure that the key isn't stripped. Make sure the linkage from the pedal to the hydro is tight as well. Also check the mounts. If the whole thing is moving it may effect belt tension. It could be something inside the tranny but I'd try to eliminate all external causes first.

It might be your transmission drive belt pulley starting to strip and go out. The pulley metal is softer than the shaft and is known to strip out. When mine went out it, it went out quickly and made a loud screeching noise. I could barely move forward or backwards, especially on grades. I replaced the pulley (a $20 John Deere part) and also changed my transmission fluid as long as I had the unit out. Tuff Torq recommends changing from the original factory 10/30w oil to Castrol Synthetic 5/50w. Mine works like brand new now.

Contact Tuff Torq Tech Rep. Derrick Dalton. He is very helpful and may be able to help you pinpoint the cause of your problem for your particular model transmission. Good luck!
