Default Series II supercharged engine & 4T60E-HD

I checked Alldata, but I'm not good enough at navigating it to figure out how to find what I'm looking for. I basically supposed that since the 95 NA is a Series 2 with a 4T60E transmission, I could use the wiring to make a supercharged S2 run with the transmission in my car.

It seems the transmission in my car has a lot of vacuum goods as opposed to the 65, which has a lot more electronic stuff. I've got about 40K miles on the transmission, and I wouldn't mind keeping it. So, if I were to start looking for information, first under which category in Alldata would I find what I'm looking for; and where here do I start searching? I don't believe this has ever been attempted.

you don't have a 4T60e-HD in your car, you have a 4T60e.

If you plan on doing a S2SC swap in your car, plan on getting the 65HD trans as your 60non-HD will not hold the power. Look for a complete front end drop out, including PCM, wiring, engine, trans, subframe, axles, etc...

So, the 94 SC has only a 4T60E? Even with its supercharger? That is strange. I know that the last time the transmission was rebuilt (previous owner), someone broke the pan, bent it, or something. Then, someone else got a replacement pan for the car from a junkyard, and it only reads 4T60E. I'm not really sure about how to check. In fact, now that I checked, Alldata tells me that I have a 4T60E. That is weird. Where do I go from here?

I'm sorry, I totally misunderstood you. In your first post you mentioned a 95 NA. That is what I was talking about. I didn't even look at your sig

still, this is the best route:

Is there somewhere that I can look into doing this swap? I would like to know how to hook up a S2 L67 to a S1 L67'* transmission. I'm aware it should be possible because of the L36 engine in the 95'* body with the L27'* transmission. If I could do this, it would be really awesome.

Do you mean it bolts right up just with the bolt holes, or to everything so it'* just a direct swap and I can run, shift, and so on?
