Clutch problems of the 1999 Ford F-350

(1) driving my 1999 Ford F-350 super duty diesel home from work. (2) I pushed in the clutch pedal to shift down, the clutch failed to release and the pedal stuck to the floor. I ended up in the middle of an intersection avoiding a collision. The truck is undriveable, blocking traffic, and required towing. (3) the clutch release for had cracked and bent also causing a failure of the clutch hydraulic circuit. Replacement of the release fork and hydraulic circuit restored the truck to operation condition. The part number of the new clutch release fork was different than that of the one removed, leading me to suspect a problem with the stock release fork. Original release fork part number f61a-7515-be. New installed release fork part number yc3z-7515-bb. I have retained the old release fork at my home address.

The vehicle's clutch mechanism failed while driving. As a result the vehicle was unable to come to an complete stop. Please provide any additional information.

Vehicle was at a complete stop and manual clutch went out. Vehicle lurched forward through a red light. .

Consumer has difficulty getting the transmission into gear and when shifting, when the transmission does shift gears, there is a grinding noise, the free play in the clutch is always different, sometimes the clutch would engage when the clutch pedal was near the top , other times the clutch would engage when the clutch pedal was pushed all the way. The consumer was informed that there was a 6 inch piece of rubber hydraulic hose in the hydraulic line of the clutch assembly, so when the vehicle was warmed up, it expanded instead of staying ridged. Ford is aware of the problem and updated the clutch assembly, however, the consumer was told that problem is considered a wear item.

Low clutch engagement causing the clutch to release with pedal against down stop or not to release at all. Had truck towed for safety reasons. When the clutch doesn't release this could cause an accident and failure to be able to stop vehicle when clutch goes all the way to the floor and not disengage clutch.

While clutch is fulley depressed and in gear vehicle will take off. Contacted dealer. Replaced part, but problem reoccurred.

Whenever driving at various speeds clutch would go out. Would have no prior warning. Had taken to dealership at least 4 times, and clutch has been changed 4 times. There isn't any indication of cause of problem. It still exists.

Clutch hydraulic release system failed catastrophically, causing vehicle to jump forward immediately and violently. Fortunately the car in front of me was far enough away so that I didn't hit it, before getting vehicle stopped. On investigation, I found that the roll pin which holds the clutch line into the slave cylinder had backed out, and allowed the high pressure line to disconnect. When this happened, the clutch engaged violently, and the vehicle lurched forward on engine power. This could have caused a major accident, if any of the circumstances had been different.

The plastic retainer located where the clutch pedal engages the rod for the clutch master cylinder wears out allowing the rod to disengage the pedal assembly without any notice of inpending failure. This happened to me in a crowded parking lot at the canton trade days. Luckily I was in 1st gear and was able to idle to a parking space without hitting anyone or anything. Once the pedals comes loose and the engine is stopped it cannot be restared without the pedal assemble being in place. This problem can be avoided by returning back to the old style ball and socket set up used on older vehicles and doing away with the plactic pieces in the setup. Had I been behind someone or been in a downtown driving situation where a pedestrian been in front of me such as a stop light when it decided to come loose the outcome may have been extremely serious.

Clutch did not slip at all. Was in 5th and slowing for an exit to 4th. Clutch would not engage to 4th, towed to dealer. Told springs failed and had been failing a long time. Also informed that dealer has had frequent problems and Ford has redesigned clutch assembly three times. Power steering will just go out usually in a turn. Eems to happen when engine is hot or running over hour or so.

I know many fellow Ford diesel 6 spd. Owners having clutch&transmission problems. Ford dealers tell us it's an isolated problem. I guess that's why my truck is in douglas, wy and I live in needville, TX.

Clutch replaced several times due to breakage during service/inspection.

Ie99-069; when traveling 68 mph and attempting to downshift, the clutch would not disengage, shifted out of gear. Also, in order to stop vehicle consumer applied extreme pressure to the brake pedal, but vehicle continued to accelerate, consumer then turned the vehicle off by removing the key from the ignition. Consumer has contacted the dealer, dealer has not replaced parts. Please provide any further details.

Clutch slave cylinder stuck to the floor almost resulting in vehicle hitting another, service bulletin on failure, however unable to fix due to back ordered parts. Mjs.

Clutch locks up and its impossible to shift gears. Failures occur without any warning when the clutch disc spring pockets break, jamming the clutch. If this happens in traffic it could cause a serious accident. Ford admits that there is a failure problem with clutch disc. Consumer says clutches are lasting 25k miles between failures.

I am not the only Ford F-350 truck owner having these clutch problems. I have talked to several guys who have put 3 or more clutches replaced under 100,000 miles. There is definately a problem with these clutch assemblies. These trucks are sold as super-duty work trucks, but are not withstanding the workloads they are supposedly built for. I have contacted Ford several times with no satisfaction. I feel a recall should be in order.

Clutch was replaced at 40000 miles, it needs to be replaced again. Manufacturer/dealer have been notified.

Plastic spacer in clutch assembly broke, causing clutch to malfunction. Please provide further information.

Clutch will fail when shifting from high to low. Please provide further information.

A spring keeps popping out of clutch disc and jamming it. Consumer had clutch replaced 4 times. Cause is unknown.

Standard 6 speed transmission wouldn't go into reverse or first gear and wouldn't come out of gear. This was caused by a bad clutch installed at time of manufacturing.

Consumer called complaining about having clutch problems. Stated that while driving and stepping on the clutch, clutch will not come out, and the vehicle keeps on running by itself.
