Been driving my 2005 Century for 45,000 miles now with hard shifting. Seems to be getting worse, but we decided to drive until it breaks.

Finally a great response on the BorgWarner PCS. It makes sense in what you say. I'm still driving OK with harsh shifting. If I decide to rebuild, I'll definitely go BorgWarner.

Thanks for a great response.

I had the same problem. Cost me $40 bucks to fix it. It's called a shift kit. Works great, never had a problem since.

What exactly is this Shift Kit, and where can I get one?

Because your life isn't at risk.

Also have a 2000 Century with the same hard shifting problem, and would like to know what shift kit to use and where to get it? Thanks.

I have a 2000 Buick Century. It too has the transmission issue. I manually shift it to prevent the noise and hard shifting. But sometimes in traffic, it's hard to do, then the whining underneath starts. Pull over, shut it off, then start. Why bother with it? Time for another car!

Did your hard shift problems go away after spending all that money??

The fan motor working only on high is almost always a resistor problem. Buy the part for about $35.00, and put it in yourself.

Addressing the draining of the battery problem; mine was a door switch that went bad. It was in the on position, even when the light was not on in the car. Replaced it and the problem went away.

Also having the same problem with the tranny, intake manifold gasket, and brakes. We have also replaced the front shock assembly at 215,000 miles.

It gets 36 MPG on the highway, and 28 MPG in the city, and I will keep sticking the parts into it, because it is paid off. I also think GM should address this issue. Chrysler has a similar problem "limp mode"; it cost more to replace, and to the Toyota drivers, I like comfort when I'm driving, not getting my kidneys punched on every bump like my sister's RAV4 does.

I drive both. Honda is far better! Buick rides nicer.

Yep... add me to the long list of GMC owners with hard shift tranny problems. Mine is a 2000 Buick Century, which starts to shift hard after about 30 minutes of driving. Why does that sound so familiar on this site... Shame on GM for using the same faulty transmission for years and years after finding out about the problems. No more GM autos for me.

Personally I like my 7 speed manual in my new GM.

This is a common problem. I had the same issue one year ago. I put a shift kit in the tranny and haven't had a problem since.

I had the same problem after I bought my 2001 Buick. After 30 days I noticed noise from my transmission. The oil looked like black dirt. They deceived me.

My 2000 Buick Century starts to jerk or kind of bouncing (I don't know how to describe it) or not slip into gear after the car warms up. Like it is trying to switch gears but can't. I let my foot off the gas and that usually lets it go into gear.

It does not jerk or hesitate like that when it is cool or when I drive for short distances, normal shifting when cold, but after about 25 minutes of driving, shifts get harder. I checked my fluid level and color, and they were normal. I just added some Lucas Transmission Fix to the system; it helped a little, but not much.

It also gets hot quickly when stopped with the engine running like in a drive through or long red light. I have checked all of the fluids and they are all full. Anyone have any idea what that could be?

When I drive my 1999 Pontiac, the trans does OK all day, then when I go in a store, and come out to go home, it will not shift from 1 to 2. Why?

24th Sep 2015, 15:27

Having the exact (and I mean exact as identical) problem with my 2000 Buick Century!!! Tried Lucas transmission fix and it only helped for a day or so. So aggravating!!!

Maybe the TPS oddly enough.
