Hello everyone, I have used the search to no avail for my error code here is my issue. Location Red Deer Alberta Canada 2007 T300 (Bobcat) 2670 Hrs Joystick controls I get an error code "Right Reverse Drive Solenoid Error Off D7557" It is intermittent one day it will work just fine with no issues then one or one month later I will get the code and the right track will not move backwards. It will go forward just fine. Some times if i shut the machine down it will correct its self and sometimes it won't. Sometimes I just keep using it and it will correct itself and sometimes it won't. It is getting more frequent now so I called our local bobcat dealer and was told it could be anything from a broken wire on the solenoid to the right drive needing to be replaced and and anything in between.They asked me to bring it in for trouble shooting at 120/hr. But basically if it does not act up with them they won't be able to fix it. They said it could be the joystick controller but i don't think so because when i am getting the code I have switched from ISO to H it still won't move the right track in reverse. I have lifted up the cab and looked for broken wires but could not see any but to be honest I am not sure of where the solenoid is located. if someone who has had this issue or someone that could send me a picture of the solenoid and its location could be helpful. I have some mechanical ability and would not be afraid to change out a harness or solenoid (if i could get to it) but the right drive would be above my pay grade. Thanks for any and all help If i missed some info please ask me. Thanks Terry

directional coils are on the top of the pumps, one pointed to the front, the other to the rear..
off the top of my head i couldnt tell you what is fwd or rev, but i believe the one facing the rear of the machine is FWD travel.
with the problem being intermittent, my best guess is you have a harness problem.

all 4 coils are the same, you could try swapping coils from front to rear, and see if the fault code follows the coil.
if it doesnt the problem is in the harness.
