I have a Cub Cadet 782 Hydro. It worked great until I added some trans fluid ultra about a year ago.

I purchased the fluid from the Cub dealer. I did notice that the fluid's color is pink, whereas the fluid in my tractor is clear.

The problem that I am experiencing now is when I drive tractor, it jerks forward continuously. The only way to avoid that is to drive slowly until the unit warms up, then it works fine.

If I stop the unit for 30 minutes and restarts, I have to repeat the procedure: drive slowly and wait till the jerking stops.

Can anyone offer some suggestions?

PS: I notice the manual recommended IH TRANS fluid, whereas the fluid that the Dealer gave me was IH TRANS Ultra. Did it matter?
