this machine will work for a little whle then it looses all gears. wont move. let it sit for half hour and it works again.
fluid is ok and clean and smells normal.
shifter was changed a few years back cause it broke mechanically.
speed sensor on side of trany was changed 2 years ago.
machine was use in salt before i got it maybe 5 years ago.

im thinking a bad ground someware?

is there a chart or something of common causes for this?

when it works it works normal. and either all gears work or none.

which sensors can cause this ? for example the parking brake switch.
