Flying Finn Posted December 31, 2017 Report Share Posted December 31, 2017 We are currently in North Georgia getting ready to head toward Orlando/Tampa......or so I thought. Warmed up the truck (2001 770 with an Eaton auto-shift) and put the truck in reverse, feathering the clutch to gently back toward the trailer. All the sudden the truck fully engages in reverse (I barely released the clutch). I mashed clutch pedal to the floor....still going.....hit the brake still moving then finally had to turn off the engine to get it stopped. After I collected myself pulled well ahead thinking maybe my foot wasn't on the clutch correctly. Same thing happened. Clutch went to the floor, truck still going in reverse had to shut off the engine to get stopped. No error codes or service lights went off. Any ideas on what the heck may have happened???

Darryl&Rita Posted December 31, 2017 Report Share Posted December 31, 2017 Level in the fluid reservoir for the clutch?

Mark and Dale Bruss Posted December 31, 2017 Report Share Posted December 31, 2017 I had the clutch hydraulics go out. Scary. Pump like crazy to get the clutch to release.

rickeieio Posted December 31, 2017 Report Share Posted December 31, 2017 Since you have a 2001, I'm gonna say it's likely you have the same three pedal system as we. In that case, you have a clutch issue, not a tranny problem. As Darryl said, check the fluid level in your clutch reservoir. It's on the engine side of the firewall, outside the steering column.

adept99 Posted December 31, 2017 Report Share Posted December 31, 2017 What Mark and Rickeieio said - We have the same truck w/ 3 pedal & autoshift ....Installing a new (different) reservoir & slave is pretty easy, Bleeding it is a pain is the A$$. And despite what it looks like, don't try to adjust the linkage, per the manufacturer. PM me if you need more info.

porky69 Posted January 1, 2018 Report Share Posted January 1, 2018 Definitely a clutch issue, but don't just go and throw new hydraulics on it. There are many other things it could be...throwout bearing may have failed, pressure plate may have failed, hydraulics may have failed. Proper diagnosis is needed.

rickeieio Posted January 1, 2018 Report Share Posted January 1, 2018 What Porky69 said is true. After giving it some thought, if it were a simple matter of low fluid, your clutch brake wouldn't have worked, and the auto shift would not have gone into gear at all.

remoandiris Posted January 1, 2018 Report Share Posted January 1, 2018 Any chance the cold temps affected the clutch? Link to comment Share on other sites More sharing options...
porky69 Posted January 2, 2018 Report Share Posted January 2, 2018 I once had an 18speed manual do pretty much the same thing, stepped on the clutch, put into gear like normal and took off. Next time I stepped on the clutch it worked normally as I stepped on it but as I was letting it up all of the sudden the pedal dropped to the floor and the truck stalled from rapid clutch engagement in a high starting gear. Upon disassembly/diagnosis they found that the clutch was pretty much worn out but the main cause was the throwout bearing had come apart. Link to comment Share on other sites More sharing options...
Flying Finn Posted January 10, 2018 Author Report Share Posted January 10, 2018 Wanted to follow up and let you guys know what was wrong. The clutch master cylinder failed and the clutch slave cylinder was close behind. Also had a hydraulic line that was cracked but not yet leaking. Took the tuck to Vanguard in Adairsville, GA for the repair. Cost for the repair was $1,300.00. They replaced both cylinders, hydraulic line, refreshed the hydraulic fluid, test drove. So far so good. Never saw that one coming. If you have a Gen 2 auto-shift may want to have the clutch hydraulics looked at. Could save you a catastrophic failure like I had.

Open the hood, and look next to the windshield washer reservoir. There should be a reservoir there that has fluid in it. That's the master, Follow the tube out of the bottom down to the next object attached to the line, that's the slave is located down on the transmission housing.

Nice to know, I have a ten speed 1 to 5 and flip the switch for 6 to 10. that is something I don't know what I don't know. Time to dig into the detail. Below is a picture, is that it? It said on the cap, use brake fluid only. Volvo VNL610 M11+ 98 10 speed Mountain Aire 40' 5th 2002 Outback Power, 1200 watts Sanyo panels Link to comment Share on other sites More sharing options...

Alie&Jim's Carrilite Posted February 8, 2018 Report Share Posted February 8, 2018 That's it. I flushed mine and refilled with fresh fluid. Made a huge difference in how hard the clutch was to push. You do have to do this from the bottom though, otherwise you'll trap air in it.

rickeieio Posted February 9, 2018 Report Share Posted February 9, 2018 Yesterday, I too had a run away truck. Cruising up TX 118 south of Alpine, touch the brakes going into a curve and the cruise control doesn't shut off. Play with the stalk and finally get it to relinquish control of the ship. I grew up around some pretty good mechanics, and one lesson that was beat into my noggin was, whenever you have a sudden problem, look where you last worked on a related system. Well, during our stay in Terlingua, I removed all traces of two brake controllers. Dug around behind the instruments and sure enough, the plug was out of the brake light switch. I hadn't removed it, but it must not have been securely snapped in place by the last person who had it out. There's no end to the things that can go wrong at inconvenient times.

Ronbo Posted February 9, 2018 Report Share Posted February 9, 2018 Not a truck, but while dating my wife, the screws for the butterfly in the carb came out. Full throttle through a gas station and over a 4 ft drop off. No damage to the wife or the Chevy II.
