Type F seems to be one of the ATF formulations in the many graphs in this SAE paper about Mopar 9176, such as Figure 9

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 (ATF+3, aka 7176)
while ATF B is the new factory-fill ATF (+4 aka 9602)
... Torque Converter Clutch Performance –
The goal was to develop a fluid that would match or exceed the holding capacity of ATF A. During the course of the program, many candidates were screened for clutch holding capacity. Figure 9 shows how the new ATF B compares to the current ATF A in the bench test developed to simulate the holding capacity of the torque converter clutch.
Also shown are the results on two other potential ATF candidates from the development program.
ATF F (Mercon?) gave lower coefficients in this test compared to ATF A. and also caused some slippage in the proprietary Chrysler TCC test. However vehicle shift quality performance of ATF F was acceptable.
On the other hand ATF G (Dexron3 ?) gave acceptable TCC performance but provided harsher shifts in the vehicle
