Ford F-150 Has No Over Drive
Q. Vincent, My overdrive does not work on my 2004 Ford F-150, new style not the Heritage, with the 5.4 liter V-8. First through third work fine and reverse, but if I leave the OD engaged the RPMs goes way up and the truck slows down.
I heard that there are solenoids inside the transmission that might have failed? When I call a dealer all they say is it will cost anywhere for $1,500.00 to $2,500.00 to check it out. I checked in to a reconditioned transmission form FOMOCO and that will come with a 12 month/12,000 mile warranty with a cost of $1,700.00 plus my time and labor to install.
I guess I hate the idea that the dealer will say that the transmission will need to be rebuilt and I know that I will get a limited warranty of maybe 60 days.
Looking for your advice before I go in to the dealer; since todays transmissions are more advanced than say the old C-4s or C6s. My truck is a 2WD Super Crew with the 4R75E transmission with 63,000 miles.
A. If there is an electrical fault the PCM and/or TCM would pick it up and set a DTC. So the first thing to do is to check it for codes. If no codes are found, then the fault is probably mechanical.
The next thing I would recommend to do would be to drop the transmission pan and see if there are any "chunks" in the bottom of the pan that would indicate broken parts. There may be a magnet in the pan with "fuzz" on it. This is normal to a certain extent.
If you don't find any "chunks" then replace the transmission filter and refill the transmission with the correct type fluid and cross your fingers.
Fluid Type Specifications: 4R70E / 4R75E Motorcraft MERCON V ATF. CAUTION: MERCON V is not interchangeable at this time with the current MERCON service fluids.
If you still have no OD, have an independent transmission shop confirm internal engine damage. If this is confirmed and you need to rebuild or replace the transmission, you have three options. One, have this transmission rebuilt. Two, get a used transmission. Three get a remanufactured transmission. Of the three options, I think number three is your best bet. You can get a remanufactured unit from Ford or one from an independent re manufacturer.
Personally, I deal with Jasper Engines and Transmissions. I have never gotten a bad unit from them. They also offer a 36 month/75,000 mile warranty. The unit I priced was $1,895.00. (You can confirm this with your VIN.) The same unit from Ford is $1,811.96. So the only consideration is who has the better warranty. I don't have warranty information from Ford so I can't confirm or deny the 12 month/12,000 mile warranty.
