I had my 425 rebuilt last summer. Taking the trans apart was at times difficult because all of the internal seals in the trans had turn soft and mushy. He said it was a good thing that the rebuild occured now because it probably wouldn't have lasted more than another couple of hundred miles. When asked if I had used any transmission additives with the fluid, my answer was no, that the only thing that the trans has seen is...when first installed I used Amsoil ATF and later, when I changed trans fluid because I had trouble finding Amsoil, I had switched to Mobil 1. I don't know if any one else has experienced this but in my mind and the rebuilders mind, there is to a minor degree, evidence that the two brands may not be completely compatible. So, FWIW, I would not mix these two brands. JWIT
Other explainations are welcome.
