I have a craftsman lawn tractor model fs5500 series and when I use it for moderate to heavy work I can only use it for about 5 to 10 minutes before it loses pulling power the motor runs fine but just won't pull and the automatic transaxle will get so hot it will burn you to touch it do I need to check the fluid or what any suggestions would help I cannot find where to check the fluid at or even a drain plug to replace the fluid

Post model and serial #.

I can post a diagram then.
