Vaccum leak, maybe?
Ok guys, I have allot of stuff on my bonnie fixed, but after i got the harmonic balancer fixed I seem to notice another problem. I should note as I mention in another post I have some kind of brake fluid leak (pretty sure) and when i press the pedal it goes half way to the floor and then the brakes work. I notice that when i pump the brake pedal a few times in park or neutral (while there is no load on the trans) that the pressure on the pedla increases and RPM'* seem to change (go up) is this a vaccum leak? I have a feeling it is. Or maybe a brake booster, but that would explain the leak, or would it? I know there is no fluid on the firewall.
Edit: I also whated to add that it seems my trans will not lock the torque converter until 47 -50 MPH, is this normal? Or would this be a symtom of a vac leak? It shift and drives fine, sometimes it does rev up a little before locking.
thanks for the input,
