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.
