I want to see if it'* my cat (clogged) but it seems that my downpipe end is larger than 2.5, is this normal. If I recall, I measured the outer surface of it and got like 9 or more inches, I kind of forgot. I was going to use band clamps to put a test pipe in between.

Does that car have a vacuum modulator on the transmission?

What effect would it have if the vacuum line is off of it? Or the modulator is defection? I recall a problem with a downshift lever linkage on a car I had got ice packed into it on the way home from airport. It drove really funny until the engine compartment temp got up enough to melt the ice away.

Another possiblity is a defect inside the torque converter.

Who'* the transmission expert around BonnevilleClub?

Thats whats still in my mind ever since I experienced this, that it'* a vac prob. but all my fittings are good. Isn't there a way to test your vacuum pressure? I still need to find out the facts on the end of this downpipe.

Since I drove home today from school which is about 13 miles, my bonnie drove better than ever. I thought I was in the BMW. I didn't do anything to the car, but I wonder how long this is going to last. it is almost 70 degrees today, so something temperature was could be wrong with my car. I'm finna go take it out for a drive again and see if it drives normal.

Well, it only lasted for about 2 days. It'* back to it'* regular self.

I was going to check my rear brakes again for dragging and I can't get the drum off, it'* like it'* welded on. My parking brake release lever isn't working, even when I put the parking brakes on (but they don't stay on, the clutch kind of raises back up) The brake shoes nor parking brake shoe isn't gripping to te drum to stop it from being remove. Any help?
