Hi what is the best gearbox oil for a 2004 ram srt10 6 speed manual
Thank you for your information but I checked this oil and it is for an automatic my one is a manualThe factory fill will never hurt you. It will be quieter and the syn fill is like Goo. However, if you wish to minimize parasitic drag, speed up shifting and maintain the OEM specification (and Tremec), the Redline D4 full synthetic fluid is awesome.
I run it and have done so since I got the truck. NO issues.

Ok thank you will try this oil in my one truckCorrect...
The Tremec APPROVED LUBRICANT. Most T56 transmission models use Dexron II automatic transmission fluid.

The D4 also meets the GL-4 specification.
