Well you could go with a Manual 4l80E. But it is a full manual unit.
I TH700 can go in it... but it would be pushed to it's limit every time you leaned on it.
Same for a Full Manual 4L65E with good shafts. It could handle it for a period of time.
What sort of driving does this car see?

Really ? What motor is it being bolted up behind ? Being as I have built sevral 4r70w's that are taking in around 1000flwhp I really don't know where you see these limitations. If this guy was smart he would try googling 4r70 ls1 or something similar. There are bellhousing options for this trans on the market now.
with the right valvebody and clutchs the 4r70w is almost as tough as an 80 3/4 the weight and the same physical size almost as a 4l60.
Wheres that downside again ?

Relax, maybe "limitations" was not the right word to use here.
I myself have built many many of these units for performance applications. I currently have one on the shelf that was slated for a 700 H/P boosted application in a Fox body. We finished it because the owner decided he wanted a Glide instead... he decided to go to a track car instead of a Street / Strip car. The 4R70W has a massive Input Shaft and Geartrain for its size, no doubt it can take a punishment.
The idea is that the components needed to swap it over to a GM block can be hard to get and can be expensive in my experience. But it was over a year ago that I looked aornd for those parts.

Thank you for the advice. I have had the need for these components once in the last 3 years. There are not too many guys who are willing to take their GM powertrains and install a Ford Transmission onto the engine.
That does not mean it is not a worthwhile endeavour, it just means that I focus on what is on my table and look towards the future with new and exciting R&D programs.
Not many folks have the need nor are inclined to do the swap you have in mind.
Thanks again.

Actually a 4R70W is a good idea that with a special bell and you have a monster I would say the 4R70W is easily right up there with the 4l80e in strength yet is about the same size as the 4l60e a little heaver.
Tomorrow I will do some research on what it would take to control it automaticaly

I have never considered the 4r70w in the vette I know there would be several custom parts needed but then so are there for the 4l80e. But I would imagine in the case of the vette while the size would certainly be a good idea the exspense of the custom parts to put it in would likley make it phrohibitive because of the unique layout of the vette drive train.

I would love to spill the beans on the company doing this, but being as they do not sponsor LS1 tech its sort of against the forum rules.
As to the C5 vette. I imagine it is doable. it would require a whole rethink however and would not be cheap. Custom shafts and bellhousing.

I think someone makes a controller for the 4L80E, TCI maybe? I'd make put some thought into the combo, and not cut corners. Mike Brown has run a 4L80E into the 7's... Amazing stuff indeed. I don't know much about the Ford trans anyone got links of a car running in the 8's with one?

Indeed PSJ.... TCI does produce a stand alone controller. As a metter of fact several companies do. The unit we prefer is manufactured by CompuShift. It really is a matter of preference though.
