Torque converter lock out switch on a 96 sport

[mccoyxx]

Hello , I have a problem ... when I drive my explorer it jerks and clicks sometimes like the front differential (4wd) is trying to engage. It literally feels like I am split second pushing the brakes (jerks and you can feel it catching on something) and it does this at all driving speeds and I have noticed its much worse when its under a load or going up a steep hill. Its not constant and when it does this is mostly when i am first pulling out or in a curve. It doesn't seem to do it near as bad when its cold outside either. Strange I know, but I assure you I am correct in saying this. I also have an issue of it trying to pull forward when I have came to a complete stop and am holding the brakes, it lunges forward like I am pressing the gas. I was told this is probably a "torque converter lock out switch" causing the issue. I don't believe it to be any major transmission problems as it shifts smooth like it should in all RPM ranges and under all dif. loads. I believe this model the 1996 has the 44 tranny in it. does anyone know the location of this switch ? I was told at NAPA it was on the outside and is a simple change, but a mechanic told me I have to pull the tranny as it is in the inside of the bell housing. Any advice or comments are greatly appreciated.

Is the AC on during "lunging" against the brakes?

My Mark 8 did that, I changed the "idle speed adder for AC" in the tune and now it doesnt do that any more.

Thanks for the response

Actually it makes absolutely no difference at all if the AC is on or the heat or everything is off ... it pretty much does it consistently ... I am under the impression that possibly the torque lockout switch may be causing the lunging at a stop, but I am almost certain that isn't the rough clunking I hear and feel when driving ... I replaced the front hubs with ebay budget models and I am wondering if I may have not gotten one with a bad bearing !! .... gonna try to check that out tom.
