Bulletin Covers:

General Motors Corporation has developed a new service fill automatic transmission/transaxle fluid which is designated DEXRON-IIE. This fluid is the preferred fluid for all HYDRA-MATIC automatic transmission/transaxles 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/transaxles.

DEXRON-IIE Advantages:

o Has better anti-foaming characteristics.

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

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

o DEXRON-IIE is back serviceable to 1949 for all General Motors automatic transmission / transaxles.

o No change in transmission/transaxle calibration or reduction in transmission/transaxle 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.
