stock tranny
A window switch will go a LONG ways towards helping it live. Consider the Mallory 685 as it has many great features for nitrous use all in one nicely priced box, rev limit, retard and window switch are all there.
Beyond that it is a crap shoot, I have watched guys spray 150-175 for a seasons, others break behind NA motors.
Give it a shot and be prepared to deal with it if it breaks. These trannies CAN be built to handle a lot, just relatively few folks are capable so if it breaks let us know and some of us who have been abusing them for YEARS can point you towards some good vendors who can either build it or walk you through a PROPER build.

ok thanks caprice. do you think it would do ok with an occasional shot of 75? that seams to be the smallest shot i can find for a nitrous kit that is made for an LT1.
and yes chavez, its out of a 1993 camaro. some of them came with the 700 and some came with the 4l60e

I think technically the 93 was a 4L60(no E) which was just really a renaming of the 700R4, 94 came the 4L60E with full electronic control.
Really nitrous with a window switch is not as hard on a tranny as one might think, you take away all the power during the shift.
My tranny was built for 550hp but at current NA power any shot of nitrous will put me beyond that and I have debated it, spoke to the builder and once I mentioned a window switch he told me to spray the hell out of it, didn't care about the power except during the shift.
IMO put a Transgo kit in it and hit it with say a 125 shot. The Transgo will provide a little extra insurance and a 125 shot is enough to be worthwhile yet still, fairly mild. Really with the stock manifolds/cam there would be little point to trying to spray more anyway, probably too exhaust choked to gain much beyond that.

ok thanks for the usefull info. the only mods i am planning on doing to the tranny is a MILD shift kit, and a cooler. i dont want it to shift much harder at all, just a little to make less slippage between shifts. i know this is off topic but what shift kit would you suggest to suit this need? im afraid the transgo would be more jerk than im looking for
Transgo is THE kit I would recommend, sounds like you just need some guidance in the setup. You are right to not want it to shift hard. On/off type shifts break hardparts, clutches are there too be used like shock absorbers as is accumulation.

It honestly depends on the condition of the trans, how many miles, how hard it was run, etc.
If this was the stock trans that's pretty old. You never really know how long it's going to last once you start the abuse.

the tranny has about 75000 miles on it but im not sure how it was treated for the first 70k. there seams to be nothing wrong with it and doesnt slip as of now, so i can only guess it wasnt raw dogged too much

so anybody else have an opinion on how my tranny would hold up to a 75 shot. other mods are in sig which arent much. im mostly worried about how the clutches would hold once it is fully engaged in each gear. 96capricemgr is working with me about how to reduce shift slippage (shift kit, window switch) so i am just worried about how it would hold once it is in 2 and 3 gear. all my plans are just in the research stage right now so i am just seeing if this is even an option without a performance tranny

As long as it is a dry kit it would be fine as long as the tranny itself is healthy, a wet 150 kit will make it start to slip from 1st to second so it is good not to be in the dope when shifting.

Well sir, a dry kit will not "hit" as hard as the wet kit, you usually dyno more with a wet kit also, the dry kit is just plain softer all together, especially depends on where you add the nozzle.

ok thanks for the opinions. i would be running a wet shot because i would be scared off it running lean with a dry shot. more than likeley i would not go over a 75 shot with the tranny i have now.
