Torque Converter? Where am I at? What is compromised?

The other thing is this.....you cannot really get an accurate measurement of stall but one way. That is if you have a manual valve body, with the car in high gear at a stand still and with your foot FIRMLY on the brake pedal, parking brake set if it's operational and slowly run the RPM up with it in high gear sitting still until you note where the tach stops going up. Whatever RPM that is, is your stall speed.

You can certainly do it in high gear rolling as described, but it will not be anywhere near as accurate.

And Kent, this isn't meant at you, because I think you get it, but there are a few in this discussion still thinking old school and confusing "loose" with "flash". Those are two totally different terms when speaking about converters, and modern technology has all but eliminated "loose".
