Looking at an '05 F-150 XL this afternoon with a 5.4 and factory tow package. Is there a way to ascertain the gear ratio and the presence of a T-Lok diff without crawling under the truck? Vehicle has 100,000 miles. Anything I should check out in particular?
View 2 RepliesI have a 06 f150 and about a month ago I purchased an edge evolution. Twice in the past 3 weeks my o/d light starts flashing and my truck beeps and it shows Trans Fault on the trucks display. When I use the edge to check the DTC it comes back as P0731. I am running the canned level 3 tune no changes and trucks completely stock other then the edge. Also both times I have been going about 10 mph down a hill without giving it any gas. Also both times of shut the truck off and let it sit for a bit to make sure I wasn't going to break something.
View 14 RepliesI have a 2002 F450 2WD AT with the common Dana 80 4.88:1 posi rear diff. If I change the ring & pinion to 4:10 do I need to change the carrier or does my current carrier fit 4:10 & lower [4.63,4.88, 5.13 etc]? Will I need to adjust my speedo readings & if so how is this accomplished? Electronically via the diagnostic port?
View 5 Repliesfor the past 2 years (ever since putting in a new battery) my Saturn as been setting off a constant alarm without the presence of the warning symbols on the dash. You know when you leave the keys in the ignition, and open the door and get that annoying klaxon alarm? that's what my car does all the time. sometimes it goes off by itself, but you usually have to turn off the car and "reboot" it. There are never any warning symbols lit up when it does this, only the alarm. I took it to my mechanic and he said that there was nothing he could do, taking out the fuse for the beeping would somehow disable the car? I will soon take a shotgun to the fuse box if I can't find out how to take care of this problem.
View 2 RepliesMy truck gear shift is stuck in Park (console type). I have been reading threads that discuss potential causes such as blown fuses, bad brake switch, bad brake shift interlock actuator, and even ignition switch. All fuses are okay. Before I try to get into all the other possibilities, I have a question around what the local auto parts worker suggested. He said that there is a small plastic piece that may have slipped down interfering with gear movement. This could make sense, especially since the white manual release lever doesn't seem to be moving.
View 14 RepliesOk I have been trying to find out what is going on with my truck and I cant seem to find anything on here that points to all the symptoms I am having. I have a 05 xlt 4x4 with 5.4. For the last 5 months or so I have been noticing a slip or grinding noise when I go up a hill and it downshifts into I believe 3rd gear. It sounds like going over rumble strips on the road but only lasts a second. It also does it sometimes when I pull out from a stop.Also when I let off gas or brake to a stop it seems to shudder a bit.
Maybe its my imagination since I keep hearing for the grinding sound, I don't know anymore.Its driving me nuts(er). It doesn't do it all the time either.It has only 65,000 miles on it and never towed. I know I am due for a total tranny flush since it never had one. Could this be the whole problem? Iv been reading other stories that sound close to mine but they never mentioned about the noise when pulling out. Could it be the rear end? I am totally lost on this one.Other then that problem it runs great. Shifts nice.
My F-150 has developed a rattle and vibration at idle that only occurs with the truck in gear and stopped (with the brake depressed.) The noise appears to be coming from the front of the truck, perhaps from the driver's side (though it's difficult to tell while sitting in the cab).
Before I go crawling around underneath with my son holding the brake while the truck is in drive--I would sure like to know where it might be best to point the flashlight.
I recently had my rear axle seals replaced due to leaking. Does the rear diff fluid get replaced on that repair since the rear diff cover comes off? Trying to figure out when my next interval for changing rear diff fluid should be.
View 1 RepliesI got burned with a smoker back in the mid 1980's and have been hesitant to come back. I am currently pulling my 5er and my enclosed gooseneck with a 6.2 gasser SRW. It has the 3.73 gears in it...not the best for towing.
I am thinking about ordering a new SD DRW 2wd with the 6.7 PSD.
Both my trailers are rated at 18000 GVW, what would be the best ratio to order? 3.73's?? 3.55? Fuel mileage will be what it will be with what ever ratio I go with. The truck will be mainly a puller. Not a daily driver.
I'm pretty sure it's not supposed to look like this.... how the heck am I even supposed to clean this out?!
View 14 RepliesI just purchased a used 2010 fx2 screw with 5.4 and 6-speed auto. How can I find out what rear gear ratio the truck has? do I have to contact a dealer to find this out or are their any web based sites that can decode the vin? Is the gear ratio marked on the truck anywhere?
View 2 RepliesNever been on a forum but I've got a 1977 ford f150 with a 400,c6 trans currently with 3.50 gears and 26.5 overall dia tires. if I was to put 34.5 inch tires and 4.56s would it drive like it does now, same speeds and rpms in all three gears and it shouldn't chug more gas than it already does... right?
If im reasking a question post link haven't found one.
Was doing some errands this morning and on the way home the transmission shifted a little strangely into 2nd. I had to let off the throttle for it to shift.
Fluid levels are correct and not burnt with no residue floating with a pinkish red color. Using Schaeffer's All-Trans Supreme.
I have read all of the threads related to the P0732 and the mechanical diode issue. Does the e99 4R100 have the mechanical diode? If not, what else could it be?
I also have the P0500 VSS sensor circuit fault which an old Ford mechanic stated could be related to a bad fuel sending unit which is definitely bad on this truck.
Am planning to go out and clean the sensor on the differential. Speedometer is working properly. I have also noticed what appeared to be a small slip when in reverse a couple of times that I initially attributed to tire spin. Is any of this related? Should I be prepared to rebuild/replace the transmission?
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 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

View 8 RepliesI had the transmission rebuilt a year and a half ago, when I took it in it came up 4th gear incorrect ratio. The guy who rebuilt it said it wasn't the original tranny that came with the car because it was modified to fit in the car. When I got it back, after a couple hundred miles or so, the check engine light would come on for a day or two then go off. When the check engine was on it would get stuck in 3rd gear, once the light went off all was well until the next time. I took it back to the guy who rebuilt it since it was still under warranty. the P1529 code came up for TCM issue. He put some sensors and a chip in and thought it fixed it, no such luck. Finally I had the cash and had it looked at by another shop and the 4th gear incorrect ratio came up as well as the P1529 TCM code. He's suggestion to fix it was to either get a used tranny or rebuild this one again. He believes since it isn't the original tranny that the tranny in there now was for a SOHC engine, not a DOHC engine and that's why the ratio in 4th gear is off and it throws the TCM code.
View 6 RepliesHave a 2003 F350 srw 4x4, 107,000 miles on it. Driving it last night tow/haul light started flashing, hooked up AE got a P0730 Incorrect gear ratio. Truck seem to do ok, cut it off went back out a little while later and the tow/haul didn't flash.... Only issues I've had is when shifting from P to R, it takes a second or two longer than it should and shifts hard when it does but it doesn't do it every time.
View 1 RepliesSo I got around and decided to fix my transmission my self. Any way I got the code PO734 from my CE light which is gear 4 incorrect ratio. So some people say its the solenoids that cause this issue, some say its the 4th gear clutch...
So, Is it the solenoid or it could be the clutch itself? Ive removed the 4th gear from my transmission today and it looks intact. No weird damage or physical like damage on it... I just don't know which to do since solenoid job i can do myself which will be about 5 hours minimum....
2005 Ford 350. I want to change the ball joints on the front axel and I cant remove the axle out of dif. to remove the ball joint housing. I have been prying and pulling and it just moves out a 1/4 inch or so .They tell me there is no ring to remove in dif before you can pull it out but why this trouble?
View 4 RepliesMy 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.
