Hello,
I have a 2004 Viper SRT10 with stock Tremec T56, but with a lot of other modifications like Paxton etc..
Dodge is now here in Spain represented by Fiat and I asked them about the transmission oil and they told me ATF4. But my owner's manual says that I should use a synthetic 75W-85 oil.
I have searched a lot in the web and a lot of cars fitted with the Tremec T56 were filled up with ATF4, but NOT the Viper due to its huge torque. I my particular case even more torque due to the Paxton supercharger.
Some say only use API GL-4 oils in a transmission. GL-5 oils are for differentials and have much different chemistry. Some oils claim both GL-4 and GL-5, but don't use a GL-5 only oil.
I can buy this synthetic 75W-85 oil here in Europe, but should I use GL4 or GL5???
I hope you can just clarify this and help me
Thank you and best regards from sunny Valencia
