Type B is the original Dexron. Dexron is a GM test standard.



I had to re-read the SAE doc, what did Chrysler develop from this, was it Dexron II? Here's the title of the SAE document again, the heading suggests something NEW:

Development and Introduction of Chrysler’s New Automatic Transmission Fluid

Dennis W. Florkowski and Tracey E. King
Chrysler Corporation

Anthony P. Skrobul
Texas Lubricants

James L. Sumiejski
Lubrizol Corporation


Then this:

TEST FLUIDS - Table 1 provides elemental analyses
and some typical physical characteristics of the two key
ATFs evaluated. ATF A represents the current Chrysler
Factory-Fill ATF, while ATF B is the new factory-fill ATF.



The SAE paper is referencing the development of Mopar ATF+4 (MS-9602) and replacement of the prior Mopar ATF+3 (MS7176E).

Notice how the more modern Mopar ATF+4 utilizes a Fully Synthetic Group III base oil from Texaco and a top notch additive package from the Lubrizol Corporation.

Mopar ATF+4 began development in 1989 so it has roots going back 23-years.

There are newer more advanced fluids on the market today.
