same isuue as a 727. too big abd bulky and robs too much power. go with a 904 or 500 trans. smaller, will hold more then enough power and doesn't rob as much power. plus i am pretty sure the 500 has the low first gear in it
a500 is a good choice unless you want any kind of stall converter, they are all lockups. I have heard of a few guys changing pumps and input shafts to the non lock up version though.
