Can i use a 1-2 accumulator piston in place of my 3-4 piston cause my 3-4 broke and i got an extra 1-2 piston.

They were the same up to a certain year. As long as the pin diameter is the same they should interchange.

What year is your car? I do carry them if you need one.

Pin diameter will be different from the 1-2 to the 3-4 accumulator piston on most all 4L60Es, unless somebody swapped a 700R4 style big pin 1-2 accumulator housing onto the 4L60E (which I have seen), so they shouldn't be the same if everything is factory. I would recommend getting the correct piston(s) from Vince.
