I don't know a whole lot about transmissions, and am hoping someone can explain to me how I can tell when my TC is locked. I know the general idea behind TC's and lock up, just wondering how I can tell when it does it. I know you can install a light but I'm wondering about the feel. The reason I ask is I just loaded a new setting on to my truck and it is doing something I have never felt before and was told by the tuner that it is probably the TC locking up.
What I notice is that when I take off from a light in normal traffic, just a little throttle, it takes off pretty quick like you would expect. Then maybe around 1500rpm still in first gear it feels like the engine gets bogged down, and feels like that through the rest of the gears. Same feeling if I go to pass someone and give it like 1/2 or 3/4 throttle and it gears down. The truck still goes and goes pretty quick, just feels like it kind of has a load on it. If I floor it from a light or floor it to pass it doesn't feel like this. It kind of has the same feeling as the EBPV coming on, where you can tell there is kind of a restriction that makes you have to give it more throttle than you normally would. I always kind of thought TC lock up made the truck "get up and go" more rather than bog it down.
