my 2000 buick does the same thing with the transmission, but I've noticed that my engine temp. runs hotter than normal just before it starts shifting rough...if I turn my a/c on it will drop the engine temp and the transmission quits shifting rough. I'd like to find the problem with it too..is it the engine coolent getting hotter than normal causing the transmission to shift hard, or is it the transmission heating up and causing the engine to run hotter?.. Guessing,.. I would believe it's the engine coolent temp not cooling the transmission oil properly.. causing the proble... IF so.. why is my engine coolent running hotter than morm?

My 2000 century low coolent light came on about a year ago, I checked the radiator and it was full, yes. . muddy looking stuff on the cap also. I immediately thought of stop leak too..then thought someone had mixed the green with the new coolent...so I flushed the coolent system myself..I've done mechanical work for over 30 years on my own vehicles...everything from changing plugs to rebuilding engines and transmissions. ..so I know I flushed it properly..which included bleeding the air from the system after refilling with coolent. Anyway.. after that my engine began runnning a little hotter than normal. I kept an eye on it and noticed it never went above 1/2 way on the gauge. But, this summer, the transmission began shifting rough..but only when the gauge reached 1/2.. and when it cooled down.. it would quit shifting rough. I found that when I turn the a/c on..it would lower the coolent temp to normal agin. So, I can't figgure out what's causing the engine to heat up some and the transmission to shift rough when it does. Some brown stuff showed up again in the radiator again, but it only accumliated on the cap. I'm puzzled.. is the transmission getting hot making the coolent run hot or is the engine heating up causing the coolent to get hot??? Any Reply will be appreciated!

you're at step 1 of what I found in my 2000 century, I found the drain way up on the engine side of the right side of the radiator..looking from front of caR. I drained the coolent, flushed the system, and refilled the system. Only...to see the grayish brown sludge to appear again. Now my problem is with the heat gauge going slightly above the norm, and my transmission shifting hard into gears when it does go up.

on my 2000 century, it's located on the battery side of the radiator about 1/3 the way down the radiator

Does anyone have a solution to this. I'm having a similar sounding problem in my 94 Buick Century (3.1 engine).

I have a 93 Century. About 3 weeks ago the already rusted out muffler and tail pipe fell off. It ran fine for another 2 weeks. About a week ago, it was completley dead. The starter was rebuilt and it ran fine for about 2 days. Then it began to often die right after it tarted. After various tries restarting it, it usually starts, but it releases a plume of smoke and then runs and idles very sluggishly. Sometimes it dies while I am driving. There is a strong smell of gas. This only happens about half the time. It often starts on the first crank and runs and idles smoothly. I have replaced all filters and treated the fuel system and the injectors. # mechanics have looked at it, but the problem never arose when they checked it. They hooked it up to the diagnostic computer, but it didnīt indicate a problem. I live in an area where there are no Buick dealers and where I donīt have a reliable mechanic.(I am new to the area.) Can anyone make ny suggestions as to what should be checked, what the problem sounds like or give me any advice in general??? The car has only 70,000 miles on it. ( My grandmother bought it new) and it has been reliable for me up until now. Please help me if you can. Thanks.

1999 Buick Century

Hi there, I have a 99 Century and am having troubles with the head gasket and a leak on the water pump. I have been told that to repair both it will cost about $2500. I love my car and want to know if putting the $2500 work into it is worth it. In order to resell my vehicle I need to put the work into it, but what is the resale on a 8.75 year old century? The low tire light stays on continually even though the air in the tires is at the right press. Any ideas on what the issue is? I'm kinda frustrated as I don't know anything about cars and my husband knows even less. If someone can give me some info that would be great! thanks
