Ford F-150 - 1997-2003 :: Transmission Slightly Slip Out Of Gear When Accelerating From A Stop Light

I just bought a 98 f150 about a month ago from someone. The guy i bought it from said the tranny had been rebuilt about 4 months prior and i have the invoice proving it. I have lately noticed a hard shift from first to second gear, all other gears shift perfectly, but on my way from work toady the tranny seemed to slightly slip out of gear(in other words the rpms didn't shoot up, just loss of power) when accelerating from a stop light, and then it seemed to catch and started shifting ok. my question is given these symptoms is it possible that i can make this tranny last a little while longer or is it about to quit? any possible causes?

Ford Excursion :: 2003 V10 - Slight Slip When Transmission Shifts From 2nd To 3rd

I have a 03 ex with a V10. Just recently my trans has started giving me problems. Sometimes when it shifts from 2nd to 3rd I get what feels like a slight slip. Sometimes it doesn't happen at all. Feels almost like it is downshifting for a second. It also doesn't seem to make any difference whether I am hard on the gas or not.

Ford F-150 - 1997-2003 :: Rear Gear Swapping With Limited Slip

Ok so I was going to just swap the whole rear end from drum to disk but it looked to be too much difficult;t. So the rear I have has 278,000 miles in it and its starting to make noise we were thinking about swapping the gear from the disk to the drum because the disk rear has 140,000 miles on it. Both have a limited slip. And 3.55 gears but i was thinking about getting 3.73.... So my question is can I swap in 3.73 gears into a rear end with the limited slip from one with 3.55 gears? Or do I need to buy a different limited slip?

I have a 97 f150 (built 96 as 97 model), 4.2l 4x4, auto tranny. Here's the problem, when I turn my key forward to run position my starter kicks on and starts the truck, and stays engaged. I have a constant 14v at the signal wire on the starter relay (yellow red stripe). Also tranny started to slip, od light flashing. I replaced ignition lock cylinder, ignition/ starter switch, starter relay, starter, and today transmission range sensor (neutral safety switch 8 pin), same problem. Cel code that I had 2 days ago was P0707 tr sensor low input.

Ford F-150 - 1997-2003 :: Engine Seemed To Slip Into Neutral When Speed Increased And RPMs At 2000

I am having issues with my 2003 F150 4.6L truck. It just happened today when driving home. It started fine and then when I increased the speed and the rpms went up to about 2000rpms, the engine seemed to slip into neutral. I stepped on the gas but the truck would not accelerate, it was just coasting. I pulled over to the side of the road and came to a stop, but didn't shut off the engine.

After a few seconds, I proceeded to give it some gas, and it engaged in gear and accelerated...until I got to about 25mph & rpms increased to about 2000 again. It did the same exact thing....seemed to shift back to neutral so that I could not accelerate. I had to keep pulling over to come to a stop, and then slowly proceed again. I wasn't too far from home & I made it. What this issue could be?

Ford F-150 - 1997-2003 :: A/C Works For 12 - 15 Miles Then Shuts Off?

2003 F 150. 5.4 motor. 4x4. 270,000 miles. Climate control.

The A/C is ice cold.. For the first 12-15 miles, and then it shuts off and is warm.

I had it recharged at the shop just to be sure. When it works, it blows out the vent at approx. 42 degrees.. nice and cold.

This problem happens every time. Turning the climate control off and then back on doesn't work.

Shutting the truck off and then back on doesn't work. Wait a while.. Not quite sure how long, but the next time I drive it, it will work again. For about 12-15 miles and then blows warm again.

A bit of funky , moist smell to it when it blows warm.. Typical A/C smell I think.. The box could prob use a cleaning.

Ford F-150 - 1997-2003 :: 1999 - 1 To 2 Gallons Of Oil Every 150 - 200 Miles?

I am having a huge issue with my 1999 ford f-250 super duty 7.3 diesel. I am goin thru 1-2 gallons of oil every 150-200 miles I drive. I can can smell oil thru the exhaust when its running. There is a layer of oil "residue" on the engine. A buddy of mine suggested that I might have a broken O-ring on a fuel injector.....is there ANY way of testing that before tearing everything apart to get to the valve covers??

There is NO oil on the ground when left parked for a few days. I can NOT see any significant area in the engine compartment where it is leaking....

Ford Transmission :: 2003 - Should Service Torqueshift 5R110W At 200K Miles?

I have a 2003 F-250 Super Duty 6.0 4WD that has about 202,000 miles on it. I bought the truck with 83,000 miles on it and have never serviced the Torqueshift 5R110W Hi-Torque transmission. No new filters, no new fluid. In the interest of gettting the most life out of the truck I am trying to be a bit more proactive with maintenance. Does a flush/power purge will precipitate transmission problems? I am even concerned that dropping the pan and changing the filters and topping off fluid may cause problems. There are no problems presently and the dealership can't tell me that the've ever performed a transmission service for the previous owner via OASIS. Can I get away with a filter change and fluid top-off at a decent interval without incurring a condition that will require the transmission to be pulled and rebuilt?

Ford F-150 - 1997-2003 :: Trans Slipping Below 35 Miles An Hour

I have a 1997 F150 4 x 4 with the 5.4 overdrive transmission. When I accelerate from a stop I can feel the slip of the transmission until I reach exactly 35 miles an hour. Above 35 seems to be normal and have plenty of torque.

The funny thing about this is I have had a 2001 Windstar same 35 miles an hour. I have also owned a 1997 Ford Explorer with this exact same issue. Three different motor and trans combination that will not lock up until you reach 35 miles an hour.

The truck has 213,000 I have replaced all coils fuel filters catalytic converter and torque converter. Have exterior tranny cooler. engine runs good and strong. And no code I have a reader.

Ford F-150 - 1997-2003 :: 2001 - Started Shaking At About 30 Miles?

I have a 2001 f150 7700 edition. The truck has 118,000 miles and i've owned it for the past three years, the trucks great and really reliable. I drive the truck every day 50 miles to my college and about two weeks ago my truck started shaking . I had just got off the highway and made it to a stop sign. I then took off and when I hit about 30 miles an hour the truck started shaking but when I hit 40 it stopped.

I said whatever and ignored it. now it does it pretty much anytime I go past 30 miles in hour. My tranny shifts good. I checked the fluid and it was normal. smelt it and it didn't smell burnt or anything still pretty red. Some days its worse then others. Also, no engine lights, tranny lights, no obvious lose parts, tires are good. It only shakes when I give it gas. I let off the gas at 80mph and it doesn't shake at all. Which is why I'm confused.

Ford F-150 - 1997-2003 :: Cooling System - Overheating Within 3 Miles?

2003 F-150 Supercrew w/4.6 V-8, 2-wheel drive, 219,000 miles and very well maintained. I'm getting an intermittent overheat condition that I can't figure out. Coolant level is good and I just replaced the thermostat. My OBDII app showed it running at a constant 207 degrees (195 thermostat) after the thermostat. Appears to have good pressure at the cap. It ran great for 30 minutes at idle and then did fine for a five mile test drive.

The next day in the morning it overheated within 3 miles of the house (heat was on) and you could smell it. Pulled over and let it sit for 20 minutes and started back up and it stayed constant at 207 all the way to work (11 miles). It sat at work for about 7 hours and ran great all the way home (without heat, with heat, with air cond). Then this morning it did it again, overheating about 3 miles from home. This time I pulled over and shut it off for about three minutes. Turned the key on without starting and the temp was already dropping again. So I started it up and it continued to drop down so I drove to work with no more issues. This afternoon again went home and it never overheated.

I'm expecting it to overheat again in the morning. I'm gonna go live on the OBDII for temps during the drive tomorrow.

Ford F-150 - 1997-2003 :: 1998 - Rough Idle At 118K Miles?

I have a 1998 Ford F150 4.6L Triton V8 with the FX4 package. As of recent I have noticed my truck tends to idle roughly every so often that I start it up and after longer trips but will run fine once I get going. I take care of my truck like its my baby. I've done everything to it that I can without getting into the engine such as replacing spark plugs, wires, KN air filter, new ignition coil packs, change oil every 5000 with best products, etc the basic tune up stuff every one should do. This truck only has 118,xxx miles on it as it sat in a barn for around 4 or 5 years due to the previous owner being in the military.

I have been trying to search for the cause of this problem but cannot exactly seem to pinpoint it myself. One unusual thing I've noticed also is that when I run the air either hot or cold when my RPM's get high, when I go up hills or punch it, the air switches from vent to dashboard(defrost). I talked to someone who said this was most likely a vacuum leak. Maybe there is a correlation between the two? I'm not exactly sure. I read online my idling problems may be from a cracked PCV elbow? I cleaned out the EGR valve also about two months ago to see if that work. I am willing to try anything myself as long as it doesn't involve tearing the motor apart!

Ford F-150 - 1997-2003 :: Lack Of Power With High Miles - Code P1151

I just bought a 2000 expedition 4.6 EB.. Just like an f150 same principles apply. Here's the issue, it has 284k miles. I realize its probably just tired and worn out but it just doesn't have any torque it seems. If you punch it above 60 it barely creeps up the speedo, my 00 f150 4wd with the same engine about same mileage was way stronger. My only code currently is P1151 dealing with the o2. Plugs are new coils and most all else is probably old. Just wondering if something is wrong and not throwing code or if its just a tired engine in a heavy vehicle?

Ford F-150 (2009-2014) :: 2009 - 4th Gear Intermittent Slip At 88K Miles

Started a while back and comes and goes. Only commonality I have found is the truck needs to be warmed up for it to happen and usually after a few hours of driving. The downshift from 5th or 6th into fourth, at times, produces anywhere from a light to violent clunk, feels like a typical tranny slip. It will do it while in cruise and it will do it if I don't have the cruise on. Can't figure out if it is going to be a tune issue or hardware.

It does it only downshifting into 4th from 5th or 6th, no other downshifting is a problem and usually the 6th to 4th produces the worst results. At highway speeds that is usually a shift from around 2Krpm to just over 3K rpm (6th to 4th) if it is from 5th it is about 2500 to 3K. Start from a stop and go WOT and there are no issues.

Having it in Tow/Haul or not makes no difference as far as I can tell. IT can do it on one hill and the next time be just fine or do it 2-3 hills in a row. After this last trip it will do it at 9K feet or at 60 feet elevation, didn't make a difference there either.

Another issue that may be hurting the computer is the truck originally came with the 235 tires, it now has 285's and the rear is only 3.31. I plan on going with 265's and maybe still a gear change to 3.73's in the future. I usually only notice this on long trips, first was a 1500mile hauling an ATV, second was last week during a 2500 mile empty. Although I have had it do it a few times locally. I figure those bigger tires can't be good especially with that high of a rear for the management system.
