I DID THE CHANG OVER DURING THE WINTER. IT TOOK ABOUT 50 HOURS OF WORK. THE DIFFICULT DEPENS UPON YOUR CAR EXPERIENCE. I DID NOT FIND IT DIFFICULT SINCE EVERY THINKG JUST BOLTED IN EXCEPT FOR THE SHIFT. THERE I HAD TO CUT THE OLD STICK BRACKET OUT AND FABRICATE A NEW MOUNTING PLATE. I REALLY LIKE THE AUTOMATICE MUCH BETTER. BOB
