Century V6-231 3.8L (1985)
DIPSTICK IDENTIFICATION
1984 AND 1985 CENTURY 3.8L MFI ENGINE 440-4T TRANSAXLE DIPSTICK IDENTIFICATION
October 1985
Dear Buick Owner:
General Motors has determined that all 1984 and some early production 1985 Centurys equipped with 3.8L engines and 440-4T transaxles were
assembled with oil filler and dipstick combinations which give an incorrect oil level reading. The transaxles on these vehicles were properly filled at the
time of manufacture as the dipsticks are not used by the assembly plants to determine the oil level. If a dealer or service facility should accurately check
and then adjust the transaxle oil level according to the dipstick reading, the transaxle would be approximately two (2) pints low of oil. This low level
could result in transaxle slippage in cold weather and during certain maneuvers, resulting in damage to the transaxle.
To prevent the possibility of this condition occurring on your vehicle, the original transaxle dipstick is to be replaced with a new correct reading dipstick.
The new dipstick is enclosed for your convenience. Rather than asking you to return to your Buick Dealer, it is believed you might wish to install the
new dipstick yourself. Just withdraw the old one, dispose of it, and install the new one in its place. Refer to illustration on reverse side of this letter for
identification and location of dipstick. Naturally, if you wish to return your vehicle to your dealer for this change, they will be pleased to assist at no
charge to you.
If you install the new dipstick, or if you have sold or traded your vehicle, please let us know by completing the enclosed postage paid owner reply card
