I wonder if anyone else has experienced this issue with the 445 transmission.
When I first crank it cold and move forward the transmission seems to pulsate or jerk abnormally a bit.
I also hear a whining sound under there that is not normal; similar to a power steering pump noise.
After only 2 minutes it seems to smooth out, and quieten down with no problem.
The only other time I noticed this was when I was pulling a heavy cart uphill once. It seems like it trying to slip in spots, jerking...

1150 hours on it now, and the transaxle oil and filter was changed at 920 hours.
(230 hours ago with JD Low Viscosity Hy-Gard.)
