Ford F-150 - 1997-2003 :: 1998 - RPMs Speed Up After Shifts Into Drive?
May 23, 2014
I have a 98 F150 4x4. I had some trans trouble so I pulled it out and had it rebuilt. Now when it shifts into drive the rpms speed up right before it shifts. What is causing the trans to do this? It doesn't do it all the time, only if I take off faster the usual which is most of the time.

I was driving my 1998 Ford F150 the other day and pulled into a driveway. At that time, the transmission quit pulling like I put it in neutral. It shifts from park and goes into reverse but not drive. It has the 4.6L and is 2 wheel drive.

I have a 2001 f150 crew cab 4x2 82k miles 4.6 with a 4r70w. Was pulling it over a curb and it popped now it will shift into reverse and load the motor like its pulling against a wall. In drive it will move some but still will lock up and stop moving. I assumed something in the rear had broken from the way it would roll a few feet and lock. Replaced the rear and still have same problem. Is there something I can replace to fix a stuck park or does the transmission need replaced or rebuilt?

1998 F150 4.6 automatic.
Had problems with battery light. Was intermittent. Battery cables wouldn't stay tight, replaced them, light stayed off. Light back on now, constant. Battery reads 12.5ish off, 14.3ish running under load (lights, AC, etc.).
When truck is started, even cold, it doesn't rev up the RPM's and then die down to idle speed. It just goes straight to around 550rpm and surges slightly up and down between there and 650ish. Can these be related?

-My pickup was parked and hit in the rear axle in January. I had to have the whole axle replaced as well as the leaf spring to frame mounts.
-I finally received the pickup back and now when the trans is in Drive it will not up-shift until the rpms reach 2500 and it is a hard shift.
-Also the speedo does not work now.
-Check engine light also came on with code P0500- vehicle speed sensor.
-I replaced the VSS at the transfercase and the ABS sensor in the rear differential with no change.

I have a 1998 f150 4x4, the truck has not been driven in a few years and it’s been outside in my driveway up on jack stands. I just rebuilt the front end and did a four wheel break job, after getting the truck off the jack stands, I can't get it to move in drive or reverse. I also noticed that when you go from reverse to park the gears grind and I can't even get it to shift into 4H. I checked the tranny fluid and it is fine, also the tranny was just rebuilt a few years before I stopped driving the truck.

Well I was trying out my four wheel drive today and it worked fine until I went to turn off switch, it would not cut off it is a 98 F150 switch is located on dash. It is stuck in four wheel high!

I have a 1998 F-150 XLT, 2WD, 4.2L, V6, just over 103,000 miles. My transmission shifts fine into reverse but when I put it into drive it is very slow to engage, sometimes it doesn't. I have to put it in drive, hold down the brakes, give it some gas and then it will engage and lurch forward. I have check the fluid level and quality. Both are fine. This just started to happen two days ago with no fore warning. No previous problems with transmission.

My t case will engage in 4 high and 4 low. so i know the switch and motor works because it go all the way to 4 low and i can feel the lower gears. BUT the front drive shaft is not turning because i know that the front diff is engaging just fine cus one I just fixed it and because when i put it in 4x4 the front drive shaft is locked in but when i take it out the drive shaft moves freely when i turn it by hand. But when I test it in gravel or mud the front wheels still ain't turning. So its gota be the t case. But what are the part that may be broken in the t case and if I can fix it wile its still on the truck.

So my 98 f150 xlt 4.6 is having a issue where the truck is jumping from 1500 rpm to about 2500 - 2600 rpm. You know sitting there trying to get up to speed. then all the sudden i look down and its at 1500 rpm. but still not really going anywhere. So i give it a little more throttle or gas and it jumps from 1500 to about 2500. Its been like this for a month but i thought it was crap fuel. What is the cause or maybe a solution?

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?

My F150 with 175,000 miles on gave me a the ol' P0305 code indicating misfiring in cylinder #5. I changed the plugs and wires using Motorcraft wires and Motorcraft AGS34FM plugs.
Now the truck idles fine, does not give a OBD code but runs rough at 2,000-2,500 rpm. Tried it out on the highway and it started "bucking" a bit. Not sure what to try next.

I have a 98 F250LD, its a Lariat, so everything electric/auto. Shift on the Fly 4x4, 5.4, 188K, Factory rear air suspension. Typical Minnesota rust. Anyway, I just noticed in the last 75 miles or so, a drive-line vibration. There is nothing until 39 MPH. Then from 39-41 MPH there is a decent vibration. Stops until 50, then from 50 MPH up it is a steady vibration. I have already changed the u-joints in the rear shaft. I have pulled/wiggled on everything else I can think of with no luck of finding of anything loose.
One thing I did notice, is that the front axle is locked in all the time. How long it has been like this: years for all I know... I can flip the switch from 2wd to 4H and 4L. It all seems to work fine, I hear clicking, the 4x4 engages, the proper lights come on/off. The front axle will pull when supposed to. The transfer case seems to be working fine, but the front axle won't disengage. I am hoping this can be fixed cheaply/easily (DIYer), and also hoping this explains my low fuel mileage.
Front axle? Where to look or what to try and fix for the vibration?

I have 99 f350 v10 4x4 and trans shifts great under light rpms but 2-3 shifts very hard. At wide open from about 35 mph it will shift down and take off like a bullet but wont shift until I lift my foot and then it bangs hard from 2-3. All other gears are smooth. I did some searching and have found some threads saying it could be an accumulator spring that is broken? Truck has 115,000 miles on it. love the truck but want to fix this before it does some damage.

A few days ago my 98 C1500 started having what I can only imagine is some type of torque converter issue. While driving at a constant speed the RPM will surge by about 500-600. This surge does not coincide with any type of acceleration, it's more like the converter is letting go and the RPM's just rise and fall back down. The fluctuations also seem to stop after about 15 minutes of normal driving. I have had no real noticeable transmission issues. At first i assumed it was my tranny fluid just breaking down so to get me home I used a bottle of Lucas.
The bottle seemed to do the trick for only a couple of days and now the problem is back...no better, no worse. The only difference I have noticed is that before the addition of the Lucas my fluid looked perfect and now it seems there is a bit of varnish. No smell, nothing seems burnt, just a little dirty. I haven't changed the tranny fluid for about 70k and the truck now has roughly 160K on it. My concern is that if I do change it the transmission will crap completely and I'll be on the hook for a rebuild.

I have a 2000 F-150 that shifts way too early. By the time I hit 30mph it is in overdrive. Does not slip and has firm but early shifts. I am thinking the speed sensor...

Have an 01 f150 super crew 4x4 with 5.4 li shifts hard from 1st to 2nd - What could be the problem?

First & main issue: I throttle on, the RPMs jump, speed drops. I think I dealt w/ this before in my old Toyota pickup by replacing the clutch master cylinder. Is that right?
Secondly, I don't know if the engine of this lil car has been rebuilt, but the smoke from under the hood has been alarming. It smells of oil, and I've seen some spots that appear to have leaking oil dropping onto the exhaust, but the smoke keeps coming from various spots.
I really enjoy driving this lil car, it's my first Subaru and my first wagon, but if the trouble is just now starting for me, at over 210,000 miles... I've replaced a few things, but I've never owned a newer(ish) vehicle (except a Harley), and come to expect to do work every once in awhile. I'm fairly regular w/ preventative maintenance, but not strict about when to change fluids or flush things (i.e. transmission or radiator). Maybe I should just sell this one and move on.
I also hit a deer the other day going pretty fast and fortunately only busted out the passenger side head light, fog light, and blinker. The other day being over a month ago. I just don't drive at night and try to avoid right turns. Any thoughts on where to get cheap replacement parts? I can't seem to find anywhere that'll sell me those plastic bits for under a few hundred dollars.. strange considering a necessary part like a master cylinder is only $40..

I just had my tranny rebuilt it doesn't shift hard all the time but it does from time to time going from 2nd -3rd and 3rd -4th I thought being new it may need to soak up some fluid so the bands can swell so I ask the shop that rebuilt it that question he said they soaked them as they rebuilt it so they should be swollen already then he proceeded to tell me it was electrical is he telling me the truth because the ck engine light isn't showing any faults and if it was electric shouldn't that have been fixed in the shop while it was being rebuilt if it was interior electronic?

I have a 97 f150 4x4 with the 4r70w and it shifts a bit slow between first and second. So I've been doing my research and figured id try to put new 1-2 accumulator piston and springs in. What are the part numbers so I don't order the wrong stuff.

Just did some trading for a 97 f150 4x4 extended cab with a 5.4 and auto trans. The guy I got it from told me that the transmission in it shifts real fast and won't downshift once it gets going and shifts hard sometimes. From past experiences I figured it might be the tps and sure enough pulled codes and I got the 122 code for voltage to low on it. Checked the wires with my multimeter and had exactly 5.0 volts to the one wire and when I checked the ground back to the battery had 12.xx volts when i tested the signal wire it had 1.0 so all my wires checked out but I am still getting the code. I replaced the sensor once already so I guess it is possible I got a new sensor that is bad or is there a chance that maybe my plugin to it is bad?
