700r4 to 460le swap?
 

Looks like there's a 460le for sale and was wondering if it could be used in a 91 Camaro with a 700r4.

It can be yes...check your pm.

4L60E would require a controller of some sort. The 700R4 you have in your 91 is technically designated a 4L60 as it has some mechanical and valve body upgrades from the mid-90 and earlier transmissions but it does not include the full electronic controls of the E model.

So yes, you could swap it in but be aware that it will require some expenditure outside of just buying a transmission.
