    my stock on in the truck locks up in 3rd but you get the point

    performance built ones usually don't lock in 3rd, think it has something to do with over powering the clutch while racing/towing and burning them up.

    Interesting. I had a stock one in the 'burb and it only locked in 4th. I sometimes wished it would lock in third, probably when I was towing something. I wonder if it's a year thing where some did and some didn't.

    There is kind of a half-shift when the converter clutch locks. You'll sense a slight change in RPM which sort of seems like a shift, but it is not a gear change.

    I do believe my trucks only shifting twice after tranny rebuild, maybe cable needs adjusted.

    How does manual shifting compare to leaving it in drive?

    TV cable is critical to the function of a 700R4. Unfortunately my experience is only with stock systems. Does it have all the right brackets and the correct cable?

    There is a lot of discussion about it here:

    It might be worth a read.

    Later yeara gm started to allow lockup in 3rd. Manually should feel shift 1-2, 2-3, 3-4 when going through 1,2,D,O. And then when lockup engages will feel like another shift.
