700r4 is technically a 4l60. Like a 400 turbo became a 3l80. But. It's best to call it a 700r4. Also.... NO 700r4 or 4l60. Or 4l60e ever came without oil cooling ports. The police and hd 700r4 and later 4l60e cases came with larger 3/8th cooler line ports. Finally calling a 700r4 a 4l60. Not a 4l60e. Is like calling a 350 a 5.7 litre...
