WE HAVE NO POWER MOST OF THE TIME. AFTER USING IT FOR 2 HOURS OR LESS IT COMES TO A STANDSTILL WONT MOVE IN REVERSE OR FORWARD. WHAT CAN BE THE CAUSES OF THIS??? CAN SOMEONE HELP ME???
first off, lets start with the basics.Is the transmission full and with the proper oil? Does the torque converter get really hot? if you've got oil and its getting hot could be it needs rebuilt which is a pretty simple deal they are not very complicated. But I would recommend doing a full pressure test on the machine to see what pressures are doing that will tell you almost everything you need to know.
There should be a dipstick for the lower unit separate from the upper. Lower half is 15w40, upper I believe is as well. They are 2 separate units. hydraulic upper and gearbox lower. Make sure the upper isn't migrating into the lower.
