additionally, they also state that if this concern still happens in cold tempatures to flush with DEXRON HP ATF part number 19300536.
you might try flushing your p/s with ATF. you can mix the two fluids so dont worry about being perfect. i know my old alero has had atf in for 30k miles. plug we have been flushings treverses with ATF on a regular basis.
