ATF IV

[Archive]

I recently received a reply from Raybestos
regarding whether ATF IV was a semi-synthetic
oil. This is the reply i got back.

One of the questions over the phone you asked was if this fluid was semi-synthetic. The 9602 is called a hydro-cracked base stock(not really a synthetic). It is designed to
significantly improve wear for hard parts(i. e. 42LE chain) and increases the ATF change interval from 30K-40K to 100K.
The only down side that we are aware of is it lost 1/2 of a point on Chrysler's subjective shift quality test(scale is 1-10) and a strong odor.

The only conclusion i can draw from this is that since the Dodge Ram is known for wearing out clutches, not broken parts, my preference would be not to use it on high powered Dodge Rams.
I would instead change the oil more often and concentrate on preventing this transmission slipping.
I have asked the question, which oil is the best for the Dodge Ram, to many of the oil companies and clutch manufactures, surprisingly they seem to think that Dextron
III is the best oil for preventing clutch slippage unless you start getting into the
oils designed for high performance. (i. e. Red Line racing formula). While i find this an excellent oil in my drag car, i have not tested it my Dodge Ram. I will be doing that
in the next little bit. I cannot seem to find out what the oil change intervals would be if using this kind of oil in the Dodge Ram.
Ask 20 different technicians get 20 different answers. Has any one out there tried the RedLine racing formula in the Dodge Ram?

Hey Bill, I've been using Red Line's C+ATF3 synthetic ATF in my 47RE since about 7k miles. When I had the transmission enhancements made at The PowerShop in April (just before the last Dyno Days), I specified the Red Line synthetic C+ATF3 at that time. Both Chuck and John couldn't believe how clean my transmission was, being devoid of foreign material as well as wear. They both said it was by far the cleanest transmission they had ever seen. I was later told by John that Chuck even speculated that I had a warranty replacement transmission installed by DC! Sounds like I'm using the right juice, eh? #ad


As for the Red Line synthetic Racing ATF, I spoke with Dave Granquist (Red Line tech. ) about this very issue. Being the, "a little's good, more's better, and too much is just right" kind of guy, I was really interested in using the Racing ATF however, he steered me away from its use, possibly due to warranty issues or TCC chatter (at the 7k change interval). The thicker viscosity of their Racing ATF as well as higher heat tolerance are some of the reasons I was interested in the Red Line Racing ATF.

If you try their Racing formula please let us know how it works... because I'm still interested!
