A/T - Incorrect Fluid Level Shows on Indicator

NUMBER: 91-T-74

CORP.REF.NO: 007102

DATE: March 1991

SECTION: 7A, 4T60-E


SUBJECT: INCORRECT TRANSAXLE FLUID LEVEL SHOWS ON FLUID LEVEL INDICATOR, REPLACE TRANSAXLE FILL TUBE

MODELS/YEARS: 1991 TORONADO EQUIPPED WITH HYDRA-MATIC
4T60-E TRANSAXLE (RPO - M13)





Some early 1991 Toronados were built with transaxle fill tube assemblies that, when checking the fluid level as outlined in the owner or service manuals, could indicate an acceptable fluid level when the actual level is up to two quarts low. This is due to oil splashing higher on the fluid level Indicator than the actual fluid level.

Current assembly plant procedures for transaxle fluid fill do not require use of the fluid level indicator to "top off" oil level. For this reason, no fluid level related problems (slippage, flare on turns, noise, overheating, etc.) are anticipated unless the transaxle has to be serviced.

When servicing the transaxle of a 1991 Toronado built prior to VIN MU301717 it is recommended that a new transaxle fill tube be installed. The new transaxle fill tube part number is 24501159.

Parts are currently available from GMSPO.

The new transaxle fill tube can be identified by a white or yellow painted dot at the top of the tube.

NOTE: If it becomes necessary to check the transaxle oil level on an eady 1991 Toronado, and a new transaxle fill tube is not immediately available, fill to the level shown in the illustration.
