Question on my 503 tym hydrostat works when first started forward and reverse and then the forward reverse quits. all the other Hydraulics work normal. Last year it was in the shop for 13 months waiting for tym to figure out what the heck was going on with it and supposedly it was a loose fitting on a valve assembly I guess in the transmission but nobody can tell me what it was or where it was.
Found underneath the floor pan access to the front bell housing area there's a dual electronic solenoid valve assembly the magnets are working but don't know if it's bleeding internally or sticking. If you hold the forward pedal or the backward pedal down long enough it'll gradually start creeping and then take off but sometimes you got to shut it off for 15-20 minutes and then start it up and then it might take off and start working and then it'll quit again anybody have any problems or issues like this that may be able to help
