the whole trans
hello all,
vaceros: I believe the whole trans. I agree with jeepsj that overheating a trans would be the end of the trans. Especially if you pull a trailer I know that heat is a major factor when you are talking about engine trans and the now power steering. It seems GM started to put on ps coolers one friend told me. If you did disconnect it please connect it back up.
hope this helps,
Don
