    My 93 K3500, someone swapped from auto to NV4500 at some point, with the 93 being all manual what tranny would have come stock??

    Was considering a Allison swap but sense the truck still has the wiring from the auto it makes more sense to have a strong 4l80 built maybe...

    4L60E would have been the original in a 1500 series.
    93 and 94 used the same trans but 95 was a different aminal.

    OK, so what is the difference between 4l80 & 4l80E, I'm thinking no wires were cut during the swap because I see in places the connectors are just empty now.

    If I were to look for a built auto tranny would it need to be a 4l80 or 4l80E , I'm guessing the "E" is electronic of some sort?

    Technically there's no such thing as a 4L80. As they are all Electronic.
    Even if it doesn't have the E at the end, it's still a electronic 4L80.

    If you would like a '95 4L80E to swap in, I know a guy that would like to take the NV4500 and components off your hands.

    IMO a 4L80E is strong enough. Put the improvements in like 5 pinion OD gearsets. Get a triple disc converter stalled for your build - just for the better lockup clutch. The converter can overcome the big RPM drops some gears have. Change trans oil every 25k miles.

    Converter lockup clutch gives me 50k OEM, and the 3rd gear overrun clutch is quickly toast with no improvement available. It's only used for compresion braking.

    I'm good with that. As time permits, I'm not going anywhere and neither is my truck. If we get down your way for a vacation in the next year or two, we'll try to drop by.

    If you're using stock electronics, you're stuck using a 91-93 EARLY 4l80e transmission. You can add in the output reluctor since Sonnax is now making replacement's, but theres not much you can do to get around needing the 91-93 valve body. Your only option would be custom programming or a stand alone controller if you can't find a 91-93 4l80e.

    didn't the vans use a TCM with mechanical injection later than 93?

    Yes they did, but it never came with 4x4. Ask those who have done the db2 swap with the GM tcm what happens in 4low.

    If it was mine, I would run the late 99 or newer 4l80e, and a stand alone controller. The early 4l80e's got alot of improvements through the years. By mid year 99 GM had the bugs worked out and most of the weak points weeded out.
