"early" 4l80e's vs "later" models for fbody swap - differences?
Aside from some minor internal differences, the biggest difference I've read about is the electrical plug connector. I was looking at the Speartech adapter harnesses for a T56 -> 4l80e or 4l60e -> 4l80e, and I don't see a different model for each plug. My 4l80e is a 93 model - will that make a difference as far as connecting it to my harness is concerned? Is the plug typically a part that gets swapped out on earlier models?

I'm pretty sure all decent builders automatically change the wiring harness to the newer design, even some shade tree shops probably do it.

If you're going to use an aftermarket swap wiring harness just get the internal wiring upgrade.

No one makes a vehicle swap harness for the old style plug.

wiring is the same early to late as i know (I just got the wireing harnesss from speartech) the later is a bit better something about the oil return in the rear, but both are the same inside.

When I talked to a couple vendors it seemed like they prefer the older ones for a starting point of a rebuild. I was told that the overdrive is stronger in the older ones so if you plan to do high speed runs with a high horsepower car get the older one. I guess the anawer may vary depending on what parts will be changed.

You don't have the later style plug.
Besides the fact it's dirty!
I know there's small nuances different between the years, just wondering if those with a sharp eye had any info on it. I was told it was behind a SBC in a "street rod" - but given the level of dust on it, maybe it was a street rod in need of a restoration.
I had read the "earlier years" had the cooling lines on the side?

It will bolt up however the 99 and later units will utilize one more bell housing bolt. You can also get a structural inspection cover that you can bolt to your engine oil pan. The unit you are talking about would basically be like bolting up a th400 or th350. HTH Vince

There are quite a few TH400 cars running less bolts then it can. We had a car that had a Shield and the installer put the bolt in place and in order to get to it we had to drop the engine. Originally before the trans install the car had Poly Motor Mounts, and then the car with to a Motor plate and the give is no longer there to let the trans hang down.
