F Series :: 99 F250 SD Speedometer Is Erratic / Trans Is Not Shifting Right


Jan 29, 2014

My speedometer is erratic, not reading correctly, and the trans is not shifting right. It gets up to 3000 RPM and I have to back off the throttle to make it shift to 2nd. Then after driving a while everything starts working right. Next time I drive the truck it does the same thing.

Ford Ranger / B-Series :: Speedometer Dial Started Climbing When Driving On Highway - Erratic Readings

On my '91 last week I was driving on the highway about 60-65 when all of a sudden the speedo dial started climbing to 70-75-80-85 and past. The odometer seems to be working ok? Still when I drive it still operates in the same manner. It never bounces around or falls back. The needle is sort of stable such if I maintain a speed the speedo will maintain even though it's incorrect. There is a slight wavering of the needle meaning it's not as stable as it use to be. With the odometer working I was wondering and don't know. Does the cable drive the needle or is it electrically controlled? I'm thinking of grabbing another instrument cluster it that is the problem, I'd like to know more about it and understand how it works so I don't just throw parts at it until it's fixed.

Ford Super Duty (1999-2016) :: 5r110 With Code P0766 / Shifting Erratic And Trans Control System Fault

The truck belongs to a very good customer of mine and is a 05 f350sd 6.0 td with 5r110 torqshift tranny. The vehicle presents with these symptoms and codes....

-there is a delay from p to r and its intermittent, sometimes it will be in a weak reverse where it wont creep unless you give it some gas, sometimes it will hit reverse hard after this. sometimes it bangs reverse
-there is a delay into drive intermittently with the same symptoms as reverse where sometimes it bangs and sometimes it will take a little throttle to get it moving
-once the trans is hot (operating temperature) it has trouble downshifting. my solus tells me sometimes it tries to start off in 3 or 5 then sometimes it will bang back down into first and almost chirp tire with little throttle input
-tow haul light will flash after several miles and then it only has 1-2-3-4 no 5-6. then the starting off symptoms get worse
-throws codes for

p0766 shift sol d performance/stuck
p2701 friction element b apply time range/performance
p2703 friction element d apply time range/performance
p0700 trans control system fault.

So far the ideas i have are as follows

replace solenoid D
direct clutch replacement and seals for corresponding drum
torque converter replacement and pump replacement
harness rub through between pcm and transmission

The truck has had similar issues a year ago. Upon testing line pressure i found it was out of spec and replaced the epc. (electronic pressure control solenoid) and this cleared most of it up . I have had the pan down many times and the fluid has not been burnt and there is little debris in the pan. nothing i would consider beyond normal wear. Tomorrow I will be dropping the pan again to inspect the magnet and fluid as well as the condition of the harness. i will post my findings at that time. I am hoping between now and then some of you will be able to point out a few possibilities to get me on the right track.

Ford Ranger / B-Series :: Erratic Shifting And Flashing O/D Light

I have a 2003 Ford Ranger, recently I had the heater core fail. One thing that happened during the heater core starting to leak is the "THEFT" light came on brighter than normal and no longer flashes when the truck is off. Also when the theft light started acting up the O/D OFF light came on and would not shut off. If I pushed the O/D off button the Theft light will go out and then come back on after the button is released.

After the heater core was replaced the lights stayed on as described above. Every once in a while the O/D off light would stay off but then come on later. No really problem besides the lights and O/D off button not working. Now today the O/D off light started flashing and the truck kept shifting in and out of O/D.

I'm leaning towards a speed sensor issue. I'm going to check and see if there is any codes tonight and will post my results. One other thing that happen with the heater core leaking is the "CHECK ENGINE" light came on because the O2 sensor was shorted out. Have the O2 sensor now and plan on replacing it while I trouble shoot the erratic shifting in and out of O/D.

Civic - Honda :: 1993 - Speedometer Erratic

I have a Honda Civic EX 1993. The mechanic said that this is not due to a sensor and checked all the wires and said all of that is fine. And said only a new speedometer would fix it but I wonder if something else couldn't fix it. Quite expensive to get a new speedometer, especially if it doesn't work.

For about 2 years I have had a problem with the speedometer. It does not come on right away. In the summer it takes maybe 5-10 minutes to come on. In the winter it rarely comes on before I get where I am going (I live in a small town so about 20 minutes). Tapping on it does nothing. Once it comes on it works fine.

I rarely go on the highway unless going out of town. When I do go on the highway (high speeds) after anywhere from 10-30 minutes depending on the weather, it first flips over to about about 100 mph, and then if I hit the front of the face of the speedometer it goes to the correct speed and works fine from there on. If I only stop for a short time, it comes back on fine. If I am stopped for a long time it goes through the same thing.

Santa FE SM (2001-06) :: 2004 - Speedometer Is Acting Erratic Most Of The Time

My 2004 Santa fe speedometer is acting erratic almost all of the time , sometimes it works right. I have replaced on sensor that is easy to get too, right below the air filter and the other is below the cable, but the hard part is that in order to remove the 2 bolts holding the cable in place part of the frame or steering apparatus is partially blocking the bolt where a socket will not fit over...

Civic - Honda :: 1998 DX - Erratic Speedometer / Needle Will Sit And Quiver On 20 Mph When Going At 60

I have a 98 Civic with 218,000 miles. It's my around town car (the bigger more expensive car sits in the garage most of the time). The speedometer whacked out about a month ago. The needle will sit and quiver on 20 mph when I start it, when I'm going 60, and at stop lights. Suddenly, with no apparent reason the needle will jump to to the correct speed, work correctly and then as suddenly drop back to 20. I replaced the speed sensor (an easy job) and that didn't fix it. What else might be going on? Wiring harness? What would I do with the wiring? I do a lot of low level maintenance myself; oil, plugs, brakes, struts, but I've never done wiring work.

Elantra XD (2001-06) :: Erratic Shifting At Around 40 Mph

I have a 2001 Elantra GLS. The tranny shifts smooth. At around 40mph, it wants to shift into what I guess is overdrive. At that speed it is like it can't figure out where it wants to be and will down and upshift. Aside from that the tranny has no other problems.

Ford Super Duty (1999-2016) :: No Speedometer / Overdrive Flashes / Fuel Gauge Erratic

I'm having an issue on my 2002 F350 7.3. Today I hop in it and drive off I notice my speedometer stopped working. My overdrive light on the shifter started flashing. The trans seems like its not shifting correctly. It will eventually shift into overdrive but not always. Also now when I start off my fuel gauge raises and when I come to a stop it drops all the way to E and causes the ding and fuel light to light up. I figured this was all due to the VSS being bad. So I drove over to Autozone bought another VSS and a cheap tool set and changed it in the parking lot. No dice. I do have a scanner to pull the trans code but its late and I just got home.

Yaris/Scion & Vitz :: Auto Trans Erratic - Engine Stalls After About 10 Minutes Of Driving

I'm experiencing erratic shifting ending in a stall after about 10 minutes of driving. The trans seems like its searching for the right speed then the engine stalls. I've heard about air in the trans fluid, which is caused by fluid overfill and I've heard about MAF sensor which I replaced to no benefit. Right now I'm going to drain the pan, install a filter and refill accurately, especially as I have the pan off?

Santa FE SM (2001-06) :: 2002 - Erratic Shifting And Poor Gas Millage

2002 Santa fe 2.7l v6 trouble code p1529 p0121 p0129 p0740...

I'm having erratic shifting problems and poor gas millage. The issue began approx 2 weeks ago and is always present. The issue is hard shifting between all the gears, jerking, high tac revving , difficulty shifting from 3rd to 4th gear and throttle at times unresponsive, and like i stated earlier poor gas mileage.

This past weekend I replaced the TPS, but the TPS codes are still present. One concern I have with the replacement is that I din't detach the negative cable, which I've recently learned should be done. So I'm not sure if by neglecting to remove the battery cable I may have damaged the new TPS.

Is it true that the negative battery cable should be removed with TPS replacement?

I've also read that a faulty TCM can cause these types of symptoms as well and one resolution may be to reset the TCM by removing both battery cables.

Any information on resetting the TCM? Also, in case I decide to replace the TCM, where the module is located ?

Ford Ranger / B-Series :: Erratic Idle / Sporadic Miss / 3 Cylinders On Right Bank Dropping In And Out

Its a 1994 with 4.0, automatic, 4x4. Running fine, parked it, a week later I'm getting a bad but sporadic miss that according to the stealership is the 3 cylinders on the right bank dropping in and out. Driving down the road you can feel them drop out and when they come back its a kick in the pants like a turbo kicked in.

Shop says wires are good, plugs are good, and then lost me when they started talking around in circles and not making much sense.

What could make 3 cylinders all on the same side of the engine drop in and out? This wasn't anything that slowly came on. Fine one day, crap the next. The only thing I did prior to was replace the IAC because it was idling high, it was cruddy inside, and it looked like it was original. It was running fine after that till this issue popped up out of nowhere.

Mileage was claimed to be 178k but I'm beginning to suspect it's probably 278k.

Trans Sport :: 1998 Montana Speedometer Not Working / Connector Block?

I got a 1998 Trans Sport Montana that has a dead speedometer. The computer knows how fast the car is going because I've seen the live data. I've also changed out the cluster and the problem is still there. I have a schematic of the wire that goes from the ecm to the instrument cluster, but it goes through an accessory connector block. Where this connector block is?

Ford - Taurus :: Speedometer Stopped Working And Auto Trans Will Not Shift Out Of First Gear

What is going on with my dad's car. This car is a 2000 Ford Taurus with about 160,000 miles. In the morning, when he starts the car and drives away, sometimes the speedometer will not work and the automatic transmission will not shift out of first gear. After a few miles, the transmission will suddenly upshift and the speedometer will jump from 0 to the current speed. The door locks will also lock at the same time (they normally lock upon reaching a set speed). However, the car can be "forced" to shift, start the speedometer, and lock the doors by accelerating to 5000 RPM. The problem appears to have something to do with the vehicle speed sensor, but I don't know what exactly is wrong with that system. The car also knows that something is up as the Check Engine light is on.

What might be wrong with the VSS that causes this problem?
Why can it be forced to shift at 5000 RPMs?

Windstar :: 1998 Not Shifting Out Of First Gear - Speedometer Quit Working

I have a 1998 windstar with a 3.8. I took my daughter Christmas shopping and noticed the car did not want to shift out of first gear. I shifted it manually to second and then DRIVE and that worked until I stopped at a light. I took off in DRIVE and the car did shift to second and third on its own but it shifted late and hard. Also, the speedometer quit working and the overdive light on the shifter just turned on by itself and then went out. By the time we got home, the SERVICE ENGINE SOON light was on. All these symptoms happened in a relatively short amount of time (5 miles). I suspect something electrical but am not sure. Is there a speed sensor fuse on these cars?

Ford Transmission :: Hard Shifting / Speedometer Flickering And ABS Light On

1994 Lightning E40d... I was on my way home from work and noticed my speedometer jumping from zero to around the speed I was going on the highway. Then as i got off the exit I noticed hard shifting. It was in neutral between shifts for a few seconds and then it would go into gear jolting the truck forward. The abs light was the only thing on at the time. I tried turning off over drive only to get higher revs which scared me away from the gas pedal. Since I can't afford to replace my transmission. It happened all the sudden over halfway home from a 35 mile drive. I'm assuming it's some kind of electrical issue. What's going on with my baby?

Golf V R32 :: Clunk In Trans When Shifting From D To R

Experienced a clunk when shifting from D to R, especially when in a parking situation where you might shift back and forth a few times. I always make sure the car is not rolling and my foot is firmly on the brake while shifting from D to R or vise versa, but it doesn't seem to work. Is this normal with the DSG or should i bring it in to the dealer?
