Is it somehow possible to change the (standard 50/50) Front/Rear Power Ration of the 4x4 Transmission? I know the Porsche Cayenne uses something like 40/60 (as well as the BMW X5) and as the Touareg and Cayenne are supposed to share the same hardware I figure it must be possible to adopt the Cayenne settings.
View 20 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.
Have to do a brake job on the truck? I took mine truck in for a CEL (New EGT 12) and during the Multipoint inspection they saw the brakes were pretty worn (and wanted an upsell im sure). I only have 49k miles and the fronts only have 20% and rears 30% of the pads left. So I get to spend a few hours this weekend doing the deed. Anything special to look out for?
View 14 RepliesWas 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 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 9 RepliesI have a 3 spee Od out of a 1985 F-150 2wd . I was wanting to put it behind a Onan 6AT diesel . The engine came out of a P-350 bread truck . I runs great . I was wanting to know what the gear ratios are on the transmission . The engine has about 135 ftlbs of torque . The tranny was behind a 300 6 cyl . Iam trying to find out if this tranny will work or will I have to go to a N<!-- -->WC or TKO 5 speed .
View 6 RepliesI just got a Touareg with no manual. I have it and the Bentley CD ordered. In the meantime I need to charge the battery and cant figure out how to remove panel in front of seat. It was dead for a few months in the cold weather and I want to double check to be sure it didn't freeze and bust the sides.
Also I'm not sure this vehicle had the PDI done yet. What to look for in regards to a battery disconnect switch in the seat area. Supposedly the dealer removes these as part of the pre delivery inspection.
One last thing, with a jumpbox attached can I turn the key to a "on" position without danger of engine cranking to get it out of park? I guess what I am asking is when you insert the key and turn it to the right, is there a position past 12:00 that cranks engine, and then springs back to 12:00 when you let go of the key?
I need to roll it around my shop, but don't want it to accidentally activate the starter.

I just changed the front seal on my transmission, but its is still leaking as if I never did a thing? Did I miss something or is there something else that could be causing my problem?
About to change my front and rear pads, and I'm wondering if I need to open the bleed valve or the fluid reservoir when compressing the calipers.

The tire pressure monitor comes on when there is only .5 difference in one tire. Then it won't go off.
Also, the driver's side mirror will not program and it has a mind of its own just changing randomly every time I back in.
After changing the rear spark plug on the passenger side of my wife's truck ,the reverse went out. Its a 2000 4x4 ranger with a 3.0, and I think the 4r44e trans. Any way she said the check engine light came on and it was running rough. I determined that it had a bad plug changed it and she ran fine. I put her in reverse to see if the motor was still stumbling.
I could her the trans shift to reverse and the motor stayed running smoothly. When I took my foot off of the brake she was barely moving, like it was in 4 low. I stopped to see if there was a vac line that might have been pulled off , or any wires unplugged. Nothing. I started her up and put into reverse. no sound no anything it was the same for neutral. you cant hear any click nothing. I drove her and the forward gears are fine od works drive to 2nd has a engine brake feel. and 2nd to 1st has a engine brake feel.
I have never had a issue with this truck till I changed the spark plug. I think that it is a coincidence that that happened or I unplugged something. Any other way before I pull the pan off.
I have a 1986 Toyota Van. It has been outfitter as a small RV. I changed the front and rear Shock absorbers but it is still a very bumpy ride.
View 3 RepliesI have a 2009 f150 platinum and have been told both sides of the story now... that the front differential is sealed and need not be changed, and also that it is unsealed and can be changed. While asking this question I might as well lump in the rear differential as well. Are they both sealed or unsealed and need to be changed???
View 3 RepliesJust picked up a 2002 golf 2.0 auto for $200. Get the car home start it up and it runs great but... transmission shifts all kinds of funky. Starts in first then shifts to third. If I give it some gas it shifts down to second but has nothing there, just revs. Will not go into 4th at all. Throw my little mac scanner on it some codes come up. Only one that mattered was p0277 if I remember. Do a little search and it comes up as the g68 under the tranny mount. Change that out and had not cel. Still shifting the same but no code at all. Throw my scanner on just to see and get p0730 incorrect gear ratio.
View 2 RepliesI just purchased a F250 Gasser with the 6.2. I made sure to get it with the 4.30 rear to babl to tow a little better when i upsize the tires a little. Where I can find the drive output ratio from the transmission?

Should I replace the transmission filter on the Auto I have or just have Jiffy Lube do their thing?
I 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 1 RepliesI am changing the rear Diff fluid in my 1999 F250 Super Duty with limited slip differential. I have read in the manual that 8 ounces of friction modifier is required, ford dealer said it only required 4 ounces. I bought 8.
Also I asked for a inspections plate gasket and ford said use silicone... When I removed inspection plate it had a gasket. So, silicone or gasket or both? Differential capacity is 6.9 pints 75w/140w synthetic.
I 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 RepliesIs it true I can never have different types of tires between front and rear? Even if the size is the same? I put on winter tires the other at the front. The result was a nasty noise when I would accelerate and release the pedal suddenly... I had to switch back to my old summer and (unequally) used front tires.
I wonder why that is. Furthermore, the wear on my tires is not equal between front and back.
