DEXRON IIE A/T FLUID PREFERRED (GENERAL INFORMATION)

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 11 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 11 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.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
