Hi,my name is XXXXX XXXXX I'd like to help you sort this out.The picture to the left is the inside of your transmission bellhousing,between the engine block and the transmission.
The #2 mark is the slave cylinder. If they pick this up and show you,you will see the outside of the transmission.Now if the unit is leaking externally,you will get brake fluid on the inside of the bell housing that will seep out of the housing.(Brake fluid is used as the systems hydraulic fluid.) If the slave cylinder is leaking internally, or bypassing fluid, you will not have an external leak.To answer your question,yes the cylinder could fail like that overnight. As far as vandalism,the slave cylinder would be almost impossible to get to without removing the transmission but the lines running to it could be cut.If the slave cylinder was only seeping before it failed you might not have noticed any odd behavior.
As for the clutch,you want it to be inspected while the transmission is out. Usually a slave will last for the life of the clutch,so it maybe due for service.The slight shuddering on deceleration may be the indicator that it was coming due.Another part to have inspected is the clutch master cylinder.This unit is connected to the pedal via a plunger that has a piston /cylinder that forces fluid down to the slave through a tube. You need to check it for fluid seeping past the piston and back into the cab.
If you are available for the shop to call,they can show you the slave cylinder and the leak after they pull the transmission before they clean it up.The problem is most shops work on a flat rate system,so you can't keep them waiting.I think I answered all your questions, if you think of anything else,don't hesitate to ask.Good Luck,Chuck
PS: As far as price,I'd have to ask tomorrow at work and let you know.If you want the information,send me back a note and I'll check it in the morning.Thanks again
I had my service department work you up a price. For the slave cylinder only the labor is at 5.0 hours. If you need the complete clutch it is 1.0 hour more or 6.0 hours total.The retail price for the slave cylinder is $100. Our shop labor rate is $94/HR. so 5.0 @ $94 is $470 plus the part.You would be looking at $570 plus tax on the part for the slave cylinder.Hope this helps,if you need anything else let me know,Chuck
PS: Sorry about the picture,it seems to happen about every third one I send?
I new no one's parents would have named their daughterCustomer LOL
Anyway,you are right,the small hole in the transmission bellhousing is supposed to be an inspection hole to check for gear oil leaking from the input shaft seal and/or a leak from your slave cylinder or the line. The slave cylinder is part of the throw out bearing and it is mounted on the sleeve around the input shaft and is bolted to the bellhousing. Because of the way it mounts, you have to remove the transmission to slide the slave cylinder off the shaft.In the past the slave was mounted on the outside of the bellhousing and it pushed an arm that moved the bearing. The design you have was to replace the older style to give the bearing an even push into the pressure plate release forks making the clutch operation smoother and last longer? We are seeing less throw out bearing failure,but the clutch seems to last the same amount of miles.
As we discussed earlier,even though the slave cylinder isn't leaking,it still could have failed.I would look at the operation of the other components. He should check the clutch master cylinder for bypassing fluid internally. If this unit isn't functioning correctly,it can cause the slave to fail prematurely.Also,did he check the condition of the clutch and pressure plate? This truck has the type of pressure plate that has to be adjusted before it is installed.If not,the clutch will act like it has air in it and grind the gears. So if the pressure plate failed it could act like a bad slave cylinder. If you need the procedure for setting it up for your mechanic,I can try to put it in a file and send it. We get calls on it all the time so it must be hard to find the information.
Have I totally confused you or just put you to sleep? Let me know if it makes any sense,I'll check tomorrow at lunch for your post.Good Luck,Chuck
