    I have a 73 Camaro with a 2005 GTO drivetrain, I'm using a Fitech controller to run the engine and trans and have a 2800 stall converter and 3.73 gears.
    At about 50 to 55, the TC will unlock and lock back in, in a matter of a second or so, when it does, I can see in the data log that the mph spikes to like 124mph for a millisecond, any thoughts on that?
    Also, when I drive I get trans fluid on the floor pan, checking the trans, all the seals are bone dry as well as the vent tube. I blew air into the dipstick tube and was able to get air out of the vent tube so kinda ruling out too much pressure..
    Any thoughts?
