Does anyone know the optimum operating temperature range of the 901, and/or the the temp. at which accelerated wear becomes an issue?

...back in 2000 or 2001, I had talked with an engineer at ROYAL PURPLE, about using their stuff in my 915. He was saying that the lubrication boundary layer was so thick that it wouldn't allow the dog faced gearing the 915 to shift easily. They had no problems with the Borg-Warner and other styles. Even with the Funny Car transmissions, that usually remove every other tooth of the syncros.
Several racers had called and conveyed their problem. Royal Purple suggested using their ATF version of the lubricant in the 901/915 transmissions. Some changed to the ATF, some didn't and changed to SWEPCO thinking that the ATF fomula wasn't up to snuff. |
