Transmission Fluid Leak: 2003 Cadillac DeVille 4.6L V8 Sedan

Does your 2003 Cadillac DeVille have a transmission fluid leak? This video shows how to fix minor transmission fluid leaks in a 2003 Cadillac DeVille. Your DeVille should be running when you check your transmission fluid level, otherwise the fluid level on the dipstick will not be accurate. If your DeVille hesitates when shifting gears, is slipping 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. You may fix your DeVille transmission by adding some transmission fluid if it is low. Some vehicles are not worth the cost of expensive transmission repairs; if, after adding transmission fluid, you notice that your fluid level is low again, try adding some transmission stop leak to fix the transmission fluid leaks in your DeVille.

In Cadillac's quest for more performance and better fuel economy, Cadillac 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 DeVille'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.
