Sure enough it was low on fluid again. I checked the engine oil and realized that it is at an elevated level. My question is, is there a vacuum modulator that can malfunction and cause this? I had this problem with a Ford Explorer and the modulator was bad and when repaired fixed the problem. Am I right in my reasoning or am I missing something? Thank you for any advice- Mike
Faces forward on the front of the trans, pull the vacuum hose and look for oil, but this would smoke like crazy if it sucked enough out to overfill the crankcase ( not likely).
