The video above shows how to fix minor transmission fluid leaks in a 1999 Buick Century. Your Century should be running when you check your transmission fluid level, otherwise the fluid level on the dipstick will not be accurate. If your Century hesitates when shifting gears or seems sluggish shifting from one gear to the next (1st to 2nd gear, 2nd to 3rd gear, 3rd to 4th gear, etc.) check your transmission fluid level first. Unscrupulous mechanics will often suggest a more expensive repair, such as a rebuild, when adding some transmission fluid will fix your Century. If, after adding transmission fluid, you notice that your fluid level is low again, follow the steps highlighted in the video above to fix the transmission fluid leaks in your Century.
In Buick's quest for more performance and better fuel economy, Buick has been coming out with innovative transmissions on a regular basis. Therefore it is important to use the exact type of transmission fluid stipulated by your Century's owner's manual. Many vehicles with manual transmissions do not have a dipstick and their fluid level should be checked by an automotive technician as the car will likely need to be hoisted on a lift.
