Interesting. ***correction not gl5 it states gm and chrysler trannys.. My fault -- it was still notchier for me but it does not say GL5.
I can appreciate the info though. Anybody using penzoil? I put royal purple today and instantly noticed a better shift but royal is 18.99 a quart... hmm
From what i read the evo people use amsoil which is not local for me, oem which is not local, redline cocktail and royal purple.
