Buick - Century :: 2000 - Hard Shifting Between All Gears When Warmed Up
Nov 13, 2014
Issues with the transmission in the 2000 Century. My car shifts perfectly fine cold, but once it warms up it shits hard between all gears. Downshifts are never an issue, just up shifts. To me this sounds like both shift solenoids may be sticking or shot... I have already drained the fluid and changed the filter, added lucas tranny stop-slip, drained that out and replaced fluids again... no codes to go by and no high revs before shifts when accelerating...

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 a 1995 Buick Century with 149,000 miles that will occasional and randomly idle rough when started warm. Also, on several occasions it will idle so rough it kills the engine and I'm unable to start the engine until the thermostat reads completely cold. I've taken it to 2 separate mechanics who both are unable to pull any error codes (even after the engine has died) and are unable to duplicate the problem. When it does idle rough most of the time I can rev the engine, put it in gear and drive it for a few minutes and the problem disappears. Other times I try to put it into gear and it kills, I put it into park and try to restart the engine and the engine will start for a brief second and then die and will die faster each time I restart until the engine doesn't turn over at all. Then once the thermostat reaches 'C' it starts up like there was no problem at all.
Here is a list of recent pertinent repairs:
- Replaced Battery 12/2/11
- Replaced plugs and wires 4/11/12
- Throttle Body Gasket and Fuel Filter Replaced 3/18/13
- PCV Hose replaced 2/19/14 (last mechanic's guess on the problem)
I don't notice any signs of a rich fuel mixture or abnormal exhaust (there was a discussion with a Buick with no start that had this).

That said my wife bought a 2001 Accent 1.6L Auto while I was overseas and it's been a great car, about 8 days ago it just crapped out. The reverse went out on her so we took it to get the codes read and on the way it went in limp mode, started hard shifting between gears and wouldn't go over 45 she says. Took it in to the stealership today and they said that the trans is shot as well as showing codes for P1527, P0732, and P0734. I know what the two slippage codes are and I can prolly just replace the speed sensors and that will be fixed but I'm not sure about the reverse and P1527.

I have a 2000 Buick Century that I cannot get to start. While my wife was driving home it started to sputter (like running out of gas) and did a little back firing. She made it home and I put in some gas (Just to make sure) and the care cranks over but will not start. I have replaced the fuel filter, checked the spark plugs and replaced the CAM Sensor. The car still will not start.

My wife has a 2000 Buick Century with about 150,000 miles on it. It has been relatively trouble free. Recently, the "low coolant" light began to come on.She took the car into a garage where she was told there was oil in the coolant and the sensor had been compromised. The cooling system was flushed and cleaned and a new sensor installed. The "low coolant" light continued to come on. She took the car back in. She was told the wrong sensor had been installed. When she went back for the car the second time, she was told the oil in the coolant was preventing the new sensor from working and there was nothing more the garage could do. I went in and asked questions, primarily how serious was the condition, and couldn't get a straight answer.
We are due to drive to Florida in November. My wife would like to take it to a garage there. Is it save to drive it as is? What are the implications of oil mixing with coolant? What is causing it to happen?

[URL] I even pulled the same P0170 code. And what I need to do before I spend a boatload of money and wind up sleeping in my car instead of driving it to work or lack therof is to start a troubleshooting list starting from where Sabot's update left off, i dont even know where the vacuum line is that he mentions and if i sprayed carb cleaner on it would i get a jump in engine RPM or a stall as a test?
What I have done: Cleaned MAF sensor, changed fuel filter.
What I have not done: Checked all vacuum lines, Tested fuel pressure, Tested for compression issues due to blown head gasket.
there is also a puffing noise coming from the exhaust side of the engine, im gonna grab a bottle of baby powder this afternoon and test for air leaks, i dont believe it is a misfire...

Our 2004 LeSabre has the following symptoms - there's a clicking that occurs whenever the car is in motion, the car occasionally hesitates/bucks when shifting between gears (but not always), the radio sometimes does not go off when the keys are taken out of the ignition, we're losing about a quart of oil about every 2500 miles but there is no sign of a leak on the ground, we also seem to have reduced mileage (using more gas).
In this corner, Mechanic 1 (high price) - replace front lower control arms, sway bar, and bushing, front end alignment, throttle body gasket and EGR tube, oil pan gasket replacement, ignition switch replacement, brake fluid and coolant flush. $1900
In the other corner, Mechanic 2 (low price) thinks it's just the spark plugs and wires that need to be replaced, the wires, replace air and fuel filter, and PCV valve - $450
We had the oil changed about 2500 miles ago, replaced the air filter then. The oil change place suggested a coolant and brake fluid flush. I've used mechanic 1 in the past and they have replaced my head gaskets a couple of times and I suspect they are ripping me off.

My dad has a 2001 Century that started out shifting hard, like when you'd go from reverse to drive it would jump. He ignored it. It started slipping and not wanting to go up hill. It began to leak fluid. Got the lines replaced, he was driving home and said he had to put it in 3rd to make it go because it quit moving in drive.

2000 Buick Century Custom with 140K miles: Service Engine Light came on. Re;placed gas cap, light still on. Took to dealer who replaced HO2 sensor, light still on. Took to dealer who found no problem but charged $100 for looking. Light still on. Took to dealer who said it needed two major parts. Light still on. Took to another mechanic who could find nothing wrong. Light still on. Is there hope?

My 2000 Buick Century has both ends of the front sway bar broke partially at both ends-the bottom half of the flattened tubular terminal has cracked away. Would it be worthwhile to just have the cracks welded back together without removing the sway bar from the car, after removing the sway bar from the bushings and mounting bolt hardware?

My 2000 Buick Century has an issue that whenever it rains really hard, after driving a while the ABS, Trac Off, and Service Vehicle Soon lights come on. I am assuming that part of the electrical connections are getting wet and causing the lights to come on. When there is no rain, obviously the lights don't come on. It's only done it one other time and it did it today. I was just curious what to do to fix it, before I jump into looking at all electrical connections which we all know can be hard to diagnose. By the way, the car has 64,000 miles on it if that makes any difference.

I have a 2000 Buick Century. The wiper controls are all goofy. The delay seldom ever works, just goes into slow steady speed most of the time. And they go through several more cycles when wipers are shut off. No doubt some entire multifunction module will have to be replaced.

I need to wire up a trailer lighting connector for my 2000 Buick Century but I can't find the wiring run for it. Where would I find them to be able to tap into them?

I have a 2000 Buick Century and i just recently had the fuel pump replaced because it was totally shot. Everything was fine except i realized when i started it sometimes it would crank really slowly, i thought it was the battery because the one i had in there was like 4 years old. One day it just straight up wouldn't start in a Public parking lot so i bought a new battery and it still wouldn't start. Every time i try to start it, it makes one click then a weird electric swirling sound, but wont crank at all. My buddy who has a lot of experience with cars thinks its the starter. We tried banging on it but no luck. How to confirm if this is the starter?

So I have a 2000 Buick, and it generally starts. However, twice now at random times the car hasn't started. It doesn't turn over, but makes a buzzing sound. The strange thing is, that usually after leaving it alone for a few hours, it will start as though there are no problems. I assume it's some kind of electrical issue, but I would love some input on the possible problems with my car.

My 2000 Jetta gls vr6 automatic was not shifting into reverse until it warmed up a bit, so I did a filter and fluid change, car level, warm pumped fluid while shifting gears. No problem. Next morning no forward fear, guess I split the gasket by over tighting. Had it towed home. Oh, tried to get to work, adding fluid made it go. Now now gasket and fluid. No gears at all. Generic code reader said electric malfunction on every shift solinoid, torque converter lockout and something about shift timing malfunction. Basically everything connected to ribbon harness. What's up? Did I fry it. Also I have a 2002 triptronic from my 2002 vr6, suppose that's not a bolt on?

I have been trying to self diagnose an issue with my pick up for a while now. I have an 01 Silverado 2500HD 6.0 that shifts really hard into all gears. I was told it was the transmission going out, so we replaced the transmission with a rebuilt one and it did nothing for the shifting issues. We then had the transfer case rebuilt which also did nothing for our problems. My father who has some general mechanic knowledge is certain that the free floating rear end is not turning with the correct timing for the transmission shifting. No check engine lights come on at all during these issues. When I took it to a mechanic he told me I needed a new transmission and blew me off when I told him it was just replaced.

Hard shifting from the car. sort of a slam between gears and while in gear.
Possibly a mount?

My 2004 Forester (73000 miles) with 5-speed manual, is sometimes hard shifting into gears. The Subaru agency says that there's 'not much left' on the clutch and I need a new clutch @ $1300. Does hard shifting , no clutch slipping, indicate new clutch is necessary?
