Campaign - A/T Dipstick Tube Is Too Short, New Dipstick: Overview
Number: 92C16Section: 7A
Date: June 1992
Subject:
PRODUCT CAMPAIGN 92C16 - INCORRECT LENGTH DIPSTICK TUBE
Model and Year:
1992 ASTRO VAN WITH AUTOMATIC TRANSMISSION (REAR WHEEL DRIVE AND ALL-WHEEL
To: All Chevrolet Dealers
This TSB has been supplemented by TSB # 92C16(a), dated July, 1992.
General Motors has determined that certain 1992 Astro Van model vehicles (Rear Wheel Drive and All-Wheel Drive) were built with the transmission dipstick tube assembly shorter than engineering print specifications. This condition could cause a properly filled transmission to indicate an overfilled reading on the dipstick. If the transmission were to be filled to the operating range indicated on the dipstick, transmission slippage (primarily when the transmission fluid is cold) and shortened transmission life may occur. All of the transmissions were properly filled in production except for a one month period when they were filled to the operating range on the dipstick.
To correct these conditions, a new dipstick which matches the existing tube length will be sent to all owners of record. Additionally, those owners with underfilled transmissions will be asked to return to their dealership to have the transmission fluid level inspected and adjusted as necessary.
