Ford Super Duty (1999-2016) :: F250 - Gear Ratio / Changing Trans Shift Points
Dec 1, 2013
I have a 99 f250 with some procomp (325s) that are 12.5 wide with a 6in lift my superchip tuner can change the trannys shift points but I am pretty sure a new gear ratio is needed. I dont do a whole lot of off roading with it its mainly my driving around and highway rig whats a good gear ratio that would work for me

My truck is a 2008 F250 6.4 Powerstroke 4x4 King Ranch, CrewCab, Shortbed.
I don't know which rear axle ratio it has - maybe someone can help me. the tires mounted are 275/60R17 and in fifth gear (TC locked) the engine has 2000rpm @ 70mph. I think it is a bit to much so I want to install a kit with and lower ratio. I pull trailers just sometimes and here in germany these only have 3,5tons max weight. So I think I don't need this power at 70mph. 1750rpm would be enough. How do I have to modify the front axle ratio if I get a lower-ratio-rear-axle?
I want to lower the fuel consumption. After some modifications, the truck needs round about 12-13L/100km (18-20mpg) and I think it is possible to lower this as bit.

So when I try to kick into 'passing gear' in this '01 f250 5.4l, i get no tranny shift. Whether I'm in tow/haul mode or not.

I have a 2006 F250 with the 6.0 PowerStroke and automatic transmission. I just purchased this truck at an auction about a month ago.
Today I notice the transmission is not shifting into overdrive. No warning lights. If I press the tow/haul button in no change but the tow/haul light does come on. If I press it again (to turn it off) the tow/haul light goes out but still the transmission will not shift into overdrive.
This leaves me at about 2000 RPM at 68 MPH. I just had a Ford dealer perform Transmission service last week. (20,000 miles after the last recorded service.)
I am already not happy with the service I received at the dealer so I am really hesitant to take it back to them if it is something not related to the transmission service they performed.

I recently purchased a 04 f250 with the 6.0l powerstroke. I drove it for about 3 weeks now, Ive put my trailer behind it with small loads and just today tried to use the tow/haul button. When you go to pull out the tranny never shifts from first gear?? Its pulls and runs fine until you push the buttan and no shifting........

I have a 2008 for 250 6.4 powerstroke. Issue I am having is occasionally when I shift from drive to reserve it will slam when I shift to reverse. It is an intermittent issue. What causes this and what to do?

Friend parked his well working truck and when starting it up after sitting a few days it won't shift into any gear. Lever moves as normal but the truck won't move. A soft clicking sound is the only difference to be noticed when shifting the lever. where to start? Temps are below freezing here if that matters.

I may be going to look at a 2001 F250, 4x4 with a V10 engine tomorrow. I think it is a shop truck for a business. The owner said that the mechanics told him that the trans won't shift out of low gear. It is an automatic. Maybe something as simple as a modulator valve (do they still use them)?

I have a 2014 f250 with the 6.2 and just turned 13,800 miles. I tend to drive in tow haul a lot, while not towing because I like the shift pattern better and saves on brakes while stopping. Last night I slowed to a stop sign, came to complete stop. Went to take off slowly like always and the truck was like in neutral, looked down and the indicator showed 5th gear. Let off and watched it go to 1st and took off no problem. This all took only half a second or so, seemed fine after that. What might of happened?

Whenever I manually pull my gear selector into first gear it blows one of the 10a fuses (not sure which number). I lose all gauges and accelerator pedal. It's about the fourth fuse from the right on the bottom row.

I have a 2013 F450 Platinum and I love it. I would really like to get my gear ratio closer to 3.73 for fuel economy. Have not been able to find replacement ring and pinions to go to 3.73, so my only other option is to do it through changing tire size. I have 4.30 gears and based on what I have found, 37 inch tires will get me really close to the 3.73 ratio. I want to keep my truck as close to factory as possible, but I do want to do a leveling kit.
So can I fit 35x12.50x17 Toyo MT under my truck with just a leveling kit and use the stock rims? If not, what are my other options?
I have seen the option to swap to 22" shaved Alcoa's, but don't really want to go through all of the spacer/adapter stuff.

I go out of town for work for a week and come back and my 1999 F250 V10 GAS, is acting up. It started when i tried to drive it and it didn't want to shift, it would rev up to 3000+ RPMs and finally shift really hard into gear along with the speed odo not keeping up and bouncing around not wanting to work. I also had my entire gauge cluster lit up with no key and door closed. all the lights were on and it was "dinging" like the door was open and it wasn't. you would hear it when you put your ear up to the door.
So my first thought was to change the VSS (which I did) no luck. So I started wiggling wire loops under the fuse box in the cab and the "dinging" quit.. i took it for a drive and it works like nothing ever happened. Obviously I am guessing there's a short so i brought it to my mechanic and hes saying he couldn't find anything by the fuse box but he thinks its closer or even attached to the gauge cluster itself. could this be true? Why would the gauge cluster loop throw off the shift points?

I have a '99 F250 SuperDuty Diesel with an Automatic Transmission. There is a button on the end of the gear shift which allows you to turn off overdrive -- in other words the transmission won't shift into overdrive once you press the button.
Here's my problem. I start off driving normally. I've not done nothing to the overdrive button and the truck shifts normally into overdrive. 10-15 minutes down the road, the overdrive light (which indicates the state of the overdrive button) is FLASHING. Pressing the button doesn't stop the flashing. Once this flashing starts, the only thing I notice is a much more abrupt shift from 1 -> 2 gear.

I changed the shift tube in my Excursion today. I'm trying to put the key switch back in. It will go in and rotate fairly hard. I can not get the key to release. When I hook the battery back up, everything functions as it should but it won't start, the key won't release and it still turns hard. The dash lights come on and such when the key is turned to run. I tried a different key with the same results. Everything looks good.

Iv got a 2003 6.0 stroke with 212k miles on it. Runs like a top. Done a slew of work from injectors to hpop, 2 alternators, intake, exhaust. NO tuner! Stock. Anyway recently I started the old girl up, warmed up a bit and shifted into reverse and truck did nothing. Went to drive and same thing. Held brake and revved it up and it dropped in gear. Shifts fine after that. No issues other than the occasional NO shift from park problem. Iv dropped pan and replaced all filters recently.

The kid at body shop called, he has the cab ready to swap onto the 04 gas job except for the shifter cable at the trans. I have never done one either, and do not know how to take it off. I thought it was like the old trans where it was in a plastic grommet, but the cable almost looks like it is grafted to the trans. How to get the cable off the trans shift arm?

Actually a couple of questions. I've had one oil change in my F250 6.7. Getting close to the second one. So, my question is, what is the computer using to decide when to tell you that you should change the oil? And, if you changed to a synthetic oil, could you go longer between changes? And, if so, would the truck's sensors be able to tell the difference in the type of oil being used?

Just moved into the 250 from years of 150's. Now have 98 miles and read that the tran would have noise but normal while breaking in.
whats normal, not used to this much Clunk while changing from P to D ect. More noise than used too I guess.
3.73 gears

I just bought a used 2013 F-250 4x4 and it came with the snow plow pkg. heavy duty front springs. I love the truck, but won't be plowing with it, and I don't need the rough ride (and don't like the look of the front end higher than the rear)
How hard is it to swap out the front coil springs and replace them with the "regular" ones?
