Thanks for the information everyone, and I do have a Tachometer Wagonman, so I'll try to keep an eye on it. I think that I can feel it engage/disengage but trying to keep my eye on the tach, vacuum gauge and the road and be hard sometimes for a newbie.

So how to know? The easiest way to know, is to watch for a small drop in RPM. Full lockup is about a 500 RPM drop, with the other two slightly less.

Lifting the gas pedal and re-applying the throttle will definitely tell you if you're in lockup. If the engine RPM goes up with no drop, it's not engaging. If it slips down a bit -- you're engaging.

Personally, I have a quite the issue with TC engagement. Coolant temp is a big factor. The Honda Transmission Control Unit (TCU) is the "End-All Be-All" in transmission decisions. If you engine-off coast, then it confuses the hill-logic control circuit, and will not engage the TC until the calcs satisfy a condition of higher-speed cruise. It uses engine load, speed, acceleration, deceleration, and throttle position to determine if a your going up or down a hill.

Long story short, gaining access to a shop manual will help tremendously.

Best FE to you...

I have a Chilton's manual for my vehicle but it lacks alot of information about the j30a1 V6 model that I have, most of the focus is put on the four cylinder models. Thanks for the information, how exactly does your coolant temp affect your lockup? Does it run too hot?

You can connect a light to the lockup solenoid's switched side, which will light up when the solenoid is active... it's kinda the same thing as a Vtec indicator light, a common thing among people who think Vtec is some ungodly power-adder in Hondas.

"The Vtec just kicked in, y0!"
Thank you also Christ, I'm pretty sure that I have wiring maps in my guide.
