Has anyone used the
synthetic multiweight on their 3550s? Any ill effects of using this instead of the DexronIII ? It just seems like the ATF is almost too thin in viscosity. I drained the old
oil in mine and put 2.5 qts of
Amsoil and it's shifting so much better. I just hope I don't do any damage. Easy enough to drain and refill...
Opinions?
Thanks
