Ford F350 Diesel Tranny Question????
 

On my 2001 F350 Diesel Auto 4x4 the "Overdrive Off" light keeps flashing on the shifter knob. All fluids are good. The truck seems to shift alot harder than usual. Anyone know what the problem could be? Thanks, Dave

Re: Ford F350 Diesel Tranny Question????
 

Probably a bad sensor or solenoid or something of that nature.

Dodge trannys are ledgendary for not wanting to shift down into low gear after stopping. It's the "transducer solenoid" and another sensor that that goes bad in them. They finally fixed the problem after nine years of it being a cash cow for them.

Re: Ford F350 Diesel Tranny Question????
 

You have a bad sensor, or your TCM (tranny control module) is going. Or, your OD is gone but not as likely.

most of the 6 transmissions i had replaced in my f350 did that with the light right before they went. it has something to do with the bands in the trans.

Re: Ford F350 Diesel Tranny Question????
 

How many miles on it???

Re: Ford F350 Diesel Tranny Question????
 

60K !!!! And not a whole lot of towing heavy vehicles. That sucks. :mad: Thanks for the imput, Dave

Re: Ford F350 Diesel Tranny Question????
 

Your transmission is in partial limp mode,when your computer senses ANY parameter or input on the vehicle that is out of range it cuts out the amperage to the pcs module. Normally on a ford e4od the transmision line pressure is controlled by voltage/amperage,13.7 volts and 1 amp gives it about 100psi line pressure,when the computer senses the throttle position sensor at 100 %,it cuts this amperage down to about zero giving you about 220 psi line presure so that the amount of clamping force the clutches have matches the torque output. A number of different sensors also feed the computer info to determine pcs amperage,if any one of them quits working properly it cuts amperage to zero and it starts shifting extremely hard,if you continue to drive it,it can shear parts off or explode parts. Take it to someone who can scan it and determine problem,it could be a 45$ sensor or it could be a bad connection to transmission,is your speedo working? Its common for abs speed sensor on rear axle or output sensor on rear of case up top to go bad. It could also be metal on one of the transmision sensors from a internal part failing confusing its signal but lets hope for the best!! I see you have larger than stock tires,if your not already using a chip that does speedo correction you should,i just did a e40d on a 2001 exscursion,the guy put 40 inch tires on it (it looked like a frickin artic tundra vehicle!!)and never corrected the input for speedo,the thing only got line pressure for 45 mph when it was going 60 and tranny smoked within 500 miles(he also should have regeared it with 5.13's but didn't). I'm not saying thats your problem but the taller tires do put more stress on it,good luck,Smitty

Re: Ford F350 Diesel Tranny Question????
 

Just happened to me. Is your speedo off any? Mine was and so was the flashing light on the tree and ABS light. It came down to a faulty sensor. articfriends is correct.

Re: Ford F350 Diesel Tranny Question????
 

Nope. No speedo problems just a little harder shifts. The light goes off,once the engine is turned off and it resets the OD control, but then after a few miles it starts to flash again. Tranny fluid is good and clean so I think it must be a sensor. I'll get it to a tranny shop Monday. I have 35" tires on it and the speedo is off a few miles per hour. Thanks Arctic and all. What ever happened to the days when you bought a 1 ton truck and you got a truck that was built like a tank? I want my manual shift linkages back !!!! :hothead: I swear, i'll never complain about how stiff they were again.......I'll never complain about ride noise, stiffness.....i'll never complain about getting out to lock the hubs. Give me my Dana 60 back on the front axle. Thanks again, Dave Warden

Re: Ford F350 Diesel Tranny Question????
 

Does Ford have any type of recall on these? It seems everyone I talk to has had problems with these tranny's. Dave

Re: Ford F350 Diesel Tranny Question????
 

Wanna talk tranny problems, talk to Dodge truck owners.

On Sunday morning of the Sarasota Offshore Showdown race, I had gone to my truck to get something. A guy was driving past me in the parking lot with a truck similar to mine. He asked me "had any problems with your tranny yet"? I said no, was running fine. He replied "you will"
THE VERY NEXT DAY the problem started. Wouldn't shift down into first gear when you came to a stop. Worked fine if you manually shifted it down, but would only go down to second. From the research I did I figure about 75% of Dodge trucks from 94 to 02 or thereabouts had this problem, usually between 42 and 60 thousand miles. Mine went out at 57K. Generally about a 5/6 hundred dollars repair. Dodge never fixed the problem cause they made so much money on the repairs. Was a cash cow for them.

I will NOT be getting a xmas card from the service managers at either Venice Dodge or Sunset Dodge.

I miss the days when men were men, trucks were trucks, and hockey players didn't wear helmets.

Re: Ford F350 Diesel Tranny Question????
 

O.K. The verdict is in. I took the truck into the dealership and they say the torque converter came apart putting metal throughout the tranny. :mad: They estimate the cost to be $3200.00 for the tranny rebuild !!!! This sucks. :hothead: Dave

Re: Ford F350 Diesel Tranny Question????
 

Well, at least you don't have to worry about replacing one of those $45 sensors????

That sucks....sorry to hear of your problems with the truck.

Re: Ford F350 Diesel Tranny Question????
 

Convertor failures are common. We have done many. You should be able to do better than that on the price though. You should be able to buy that trans from the dealer at around $2100.00. Installation is 6-7 hours. BTW, yours trans is a 4R100. Good luck. Sam

Re: Ford F350 Diesel Tranny Question????
 

That includes a brake job and oil change. While it was in there I told them to take care of the above and save me the hassles. I still think it's high tho, but atlest I get a 12 / 12,000 waranty on it..........Dave

Re: Ford F350 Diesel Tranny Question????
 

:d :d :d :d :d

Re: Ford F350 Diesel Tranny Question????
 

Dave, the factory unit has a 3yr\36000 mile warranty. Make sure you get their rebuilt unit. Sam

Re: Ford F350 Diesel Tranny Question????
 

Thanks Sam. I'll call them tomorrow and tell them I want the factory tranny. They were going to rebuild with factory parts but I only got a 12/12K. Thanks, Dave

Re: Ford F350 Diesel Tranny Question????
 

Wardley,

You might also post your problem on http://www.thedieselstop.com/ because there is a ton of knowlege on this site.

Re: Ford F350 Diesel Tranny Question????
 

Thanks Fin, I called the dealership and they had already started working on the tranny so they said if I wanted them to stop, they would have to put my tranny back together for a core and then buy the factory rebuilt. An increased cost of 1K and a delay of 3 more days!!!! Fkit.....I told them just rebuild the tranny and get me my truck back !!! :hothead: Dave

Re: Ford F350 Diesel Tranny Question????
 

Dave, I just priced a 4R100 and my cost is $1949.16\retail-$2259.89. The cooler is $151.17 retail, $117.91 my cost. These prices are the same nation wide. This will give you some type of guideline anyway. Too bad you are not closer to Colorado, I could help you out a little anyway. Long drive though for $700.00 to $800.00. LOL Sam

Re: Ford F350 Diesel Tranny Question????
 

If you guy's had snow , I would be there by now !!!! My wifes uncle used to live in GJ. The bill is 3K and some change. They did the tranny rebuild, front and rear brakes and an oil change. Thanks for the help. I really appreciate it. Dave

Re: Ford F350 Diesel Tranny Question????
 

Dave, we got 18" of snow on the Grand Mesa earlier this week. Most snow since 1909. Figures, my daughter is getting married next weekend at the ski resort up there, Powderhorn. It is an awesome time of year normally. It is called Color Sunday. The aspens are vibrant yellow and the scrub oak is bright red. Now with the snow it will be all the more spectacular,(that's what I am telling her anyway). Enough babble here. Glad everything worked out with the truck. Sam

Re: Ford F350 Diesel Tranny Question????
 

Wait a second. The gas motors are covered only 3yr/36k miles (powertrain also), but the PowerStrokes have the 100k mile powertrain warranty. My fathers powerstroke lost a converter and it was past the 3/36 and Ford covered it no questions. The tranny is part of the powertrain. Check into this. Just thought I would put this out there.

Re: Ford F350 Diesel Tranny Question????
 

Sorry to hear you couldn't get factory re-manned w/longer warranty,Sam's right about the price. Sounds like it was kinda slow at the dealer and they need the work. If i could get customers to pay 3200$ for a trans job i'd be driving a 42 ft fountain,Smitty

Solved my Ford Tranny problem
 

Wardley...

I have installed one tranny per year in my 01 PSD, the first two Ford paid for the last one I was responsible for ($3500.00). It only had 44K on it and the truck only has 80K on it. After a furious fight with Ford, the dealership etc I decided to solve the problem.

The C4500 with the Allison trans and Monroe conversion is the answer!... note the F350 in the back ground, the new owner should pick it up next week.

The line that did it for me was from my local Ford dealership owner was this--

"So the answer to your question regarding whether a transmission a year is acceptable is not “Yes”, but it’s not “No” either – it’s “No, but”. By that I mean that mechanical breakdowns occur over a wide band of mileage. Some components last longer than others, but to have this go out when it did at 44,000 miles is within our normal experience. Do we wish it had not happened? Of course. Have some of our customers had this happen to them at this mileage level, or even less? Yes."

So I solved the hassle with the new C4500 Kodiak.

I will never buy another Ford and I am back to Chevy where I had been for 21 years!

Re: Ford F350 Diesel Tranny Question????
 

I know what you mean. Like I said, it used to be you bought a 1 ton or for the matter a 3/4 ton truck and you had a TRUCK !!!! When I was leaving after paying the cashier the salesman that sold me the truck walked up and informed me that I need to check out the new models....... I informed him that this would be my new model....... http://www.f650pickups.com/page0003.html

If I want a truck...i'll buy a truck, not a car with truck parts. :hothead: Dave

Re: Ford F350 Diesel Tranny Question????
 

ET, your Dad must have had some pull at Ford to get them to warranty the convertor after 36000 miles. The 100k mile waranty is ENGINE only(PSD). He may have had some extended warranty which is possible, but Fords basic warranty is 3\36 bumper to bumper, 100k diesel engine warranty. Sam

Re: Ford F350 Diesel Tranny Question????
 

GM is the same way,alot of duramax owners mistakenly think they have a 100k powertarain warranty when actually the 100k is only on the motor AND only covers major components.I run a small transmission shop and i also see/hear of ford sometimes going half on parts/labor on stuff thats out of warranty for some customers. There is no rhime or reason to their policy though,ive had vehicles come to me w/40k on them that the dealer flatout refused to do anything unless full price and ive heard of them fixing stuff free w/75k on them,Smitty

Re: Ford F350 Diesel Tranny Question????
 

I mean think about it. 45,000 miles and what is supposed to be a heavy duty truck tranny craps out? Back in the 60's a truck was a truck. I've got a buddy up in Maine who has a 72 one ton Chevy with over 300,000 miles on it and he's had the tranny rebuilt once. And he claims it was his fault because he started leading fluid and didn't deal with it fast enough.

You can spend 50 grand on a truck now and need a tranny in a year? Sickening...... :blaster: :blaster:
