SUBJECT: DEXRON-IIE AUTOMATIC TRANSMISSION FLUID GENERAL INFORMATION

MODELS: ALL TRUCKS, ALL YEARS


General Motors has developed a new service fill automatic transmission fluid that is designated DEXRON-IIE. This fluid is the preferred fluid for all HYDRA-MATIC automatic transmissions and will eventually replace DEXRON II. DEXRON-IIE is acceptable for use wherever DEXRON II was previously specified. DEXRON II is acceptable for use when DEXRON-IIE is not available. DEXRON-IIE can be used in both electronically and hydraulically controlled transmissions.

DEXRON-IIE Advantages:

^ Has better anti-foaming characteristics.

^ Improved low temperature flow characteristics (low temperature viscosity) and improved high temperature oxidation stability.


^ DEXRON-IIE and DEXRON II can be mixed in any ratio. No draining or flushing of system is required.

^ DEXRON-IIE is back serviceable to 1949 for all General Motors automatic transmissions.
^ No change in transmission calibration or reduction in transmission durability will occur as a result of using DEXRON-IIE.
