Century :: Transmission Won't Shift / Speedometer Showing 0
Jun 3, 2016
My 1994 century won't shift, the speedometer shows 0, my 97 service manual shows the transmission won't shift without speed input, trouble code 502, low speed sensor input, changed the speed sensor but the problem persists. I could only find 2 fuses in the front passenger side under the hood with relays in front of them, the fuses are good, all the fuses in the glove box are good, I still believe it's a fuse problem. is there a fuse on the speedometer? the speedometer is analog, not fluorescent.

I have a 2000 Buick Century that only has 70000 miles on it. I have an issue that when I drive the car for a while, the transmission will shift hard after stopping at a light or stop sign. It only does it through the first three gears. If I shut the car off and let it sit for a few minutes and start it back up, it shifts fine through all of the gears. I have not had the change to change the fluid and filter yet. The fluid looks clean and is always full. I have read that there has been a common problem with a pressure control solenoid in the transmission needing replaced to correct the hard shifting. I am not getting any kind of error codes from the PCM, so I am not sure.

I have an 02 GS with automatic transmission. The speedometer quit working and now the transmission does not shift out of 1st while driving. CEL is on but I'm waiting for a friend to come over and get the codes. It shifts into drive and reverse fine but I'm wondering if there is a speed sensor in the speedometer that signals the tranny when to shift?

Sold my mazda and got a nice 2000 2wd Ranger XLT with a 3.0L. Today the wife I and took it to town, 10 miles on the highway there, a couple in town and 10 back, didn't notice anything unusual. However I haven't this truck long so I'm not sure what is usual.
Parked it for a few hours and when went out to change the front turn signals to LED I noticed the ABS light was on when I drove it into the garage...
I checked fluid, connections and fuses, no change.I go ahead and swapped the bulbs while letting things simmer, I've had so many of these Fords sometimes the easy fix comes to me.
I backed it out and took it down the road, right away I noticed my speedometer wasn't working, so I let off the gas, when I re-applied the pedal I got nothing, like it was in neutral.
I downshifted to second and got her down and turned around as the O/D started flashing... (so glad because I would have hated walking back), then pulled her back in the garage to check transmission fluid and recheck fuses, including the ones I forgot earlier under the hood. I added a 1/4 qt of fluid then tried a road test again, this time there was a real long pause before it upshifted hard and the CEL came on.
I pulled the codes with my scangauge and got:
P0500
P2120
P0028
And decided I better look some things up and consult the gurus here before I do anymore damage tonight. I'm guessing that I'm looking at a tranny replacement possibly, but with the ABS light and speedometer failure I'm not 100% sure what is going on here...

yesterday my 89 century's speedometer stopped working. check engine light stays on. able to drive it yet but feels like it's in a lower gear. has no get up and go. Tranny has been slipping from 2nd to 3rd for a while. I think it might be the speedometer sensor. if it is the sensor will I get some power back?

I have played around with settings and wanted to see if I can have range/distance to empty showing in this screen. Doesn't seem possible. I tried looking through the online manual.

Speedometer in 2003 Trailblazer is showing wrong speed intermittently. Seems to be a known problem to GM. Is this something I can fix myself?

Town and all shops nearby have a week wait to get the truck in there. This happened once or twice a year ago but I'd pull over, shut it off and when I restarted it everything was fine. I'll be driving and all of a sudden the information display on the cluster will show a wrench signaling something's wrong(see image), then the speedometer will go to 0 and all information in center display will show flat lines. This started up yesterday but is now doing it after about 10min of driving every time I being driving. What's worse is the truck will randomly start shifting or shift extremely hard even when driving at a consistent speed. This was taken while truck was going about 45, but shows 0...

My 2009 Accent started doing the Hard/Jerky shift problem that I seen discussed in the forums. Had check engine light, scanning showed a code P0717. My question is, which sensor should install?

So I have squealing in the front of the transmission under hard acceleration. It also happens when I rev the engine while in Park. Could it be in the transmission or would just replacing the torque converter work? This is an 01 buick century with 150k miles.

My boss bought me a van, so we could start a detailing business, anyways, we got the van for . Not bad inside, and ran ok, boss didnt notice it wasnt shifting i guess. So it went straight to the shop, got new brakes, rotors, belts, plugs, and oil change. Boss did transmission flush on it to see if it would work, he said it shifted into second for him, but when i was driving home. It would not shift outta first gear.Check engine light is on. It is an automatic. I dont know what to do now,

I have a 2000 Buick Century with 212k miles on it. I would like to sell it. The problem is the transmission overdrive solenoid keeps getting stuck open. It's not a big deal once I get going 55mph or so. It's just that it's kinda "jerky" before getting up to that speed. Is this something that can be fixed by having the transmission system flushed or is it a problem of having to replace the transmission? How do I sell this car (even for dirt cheap) if I have to tell the interested persons that the transmission is going out???? Can I get a thousand bucks for it simply for the fact that it does run? I have been driving it until yesterday, fairly regularly.

Thought this would be a fairly straight forward fix of making sure that the transmission fluid was full with no air in it, as well as a few other things to try.
Well, I've run out of things I can reliably try right now. Replaced the output sensor on the transmission, filled the transmission fluid with the proper type, read error outputs. (boy was that odd, you have to turn the key three times in a certain way and it blinks codes out at you)
The error readouts point to an Oxygen sensor, and the speed sensor. The oxygen sensor I could care less about at the moment, as I can't really reliably drive the car in first gear. Once it shifts, then I'll fix that, otherwise its wasted money as I won't be driving anyways.
None of my local mechanics have a machine to read or program this thing by the way, so that is kind of out of the question.

This is on my 7.3PSD. I've observed that the 1-2 gear shift drops about 1,000 RPMs and takes a good half second or longer to do so when given a lot of accelerator pedal input. And then the 2-3 shift is a very quick and harsh shift.
If I am accelerating gently the 2-3 shift is as unnoticeable as the 1-2 shift is quick. Is the slow 1-2 shift causing the trans to protect itself and affecting the 2-3 shift? And if so, what do I do to resolve all of this? I changed the trans fluid a week ago and there is no change.

I was able to quickly diagnose the problem with our 99 T&C LXi w/3.8L.
Problem: No speedometer, wouldn't shift, check engine light came on.
Many posts suggested speed sensor. There are actually 2 of them. An input and an output. Both cost approx $20 each.
By removing the aircleaner box assembly, I had the best (relative word) access to the sensors. A 1" socket w/3" extension did the trick. I understand the access for 2000+ models is different.

Got a 2004 Chevy Impala with 99K miles. Speedometer seems to be acting sporadically often. Sometimes, it will shift 10 or 20 mph "faster" than actual speed then, sometimes, it goes to the "maximum" speed on the dial and just stays there with the car on or off. Then a few days later, starts working normal again.

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?

I have a 2000 Silverado 2500 HD, 6 liter engine. The transmission warning gauge has been showing it's overheating. I changed the filter and fluid and the gauge still shows red warning.

I bought 2004 Toyota Camry LE 2.4 couple of months ago, Been running good with no issues , no check engine light . Today I had it detailed from the inside and got it clean at a shop , then took it and changed the transmission Oil at Jiffylube . after leaving the shop the engine light came on . I then took it to a local Auto car parts and had used a car diagnostics scanner to see what was the problem and this showed up P0705 Transmission Range Sensor . I deleted it , then while driving around town , it came back on . I live in Minnesota and it is very cold here, not sure if the cold weather have to do anything with it, but i doubt it. The car looks and seems to be running ok .
