I've looked at gearvendors before and they are quite expensive. It is cheaper to find a 700r4 Tranny. DrMike
[font size=1" color="#FF0000]LAST EDITED ON May-02-01 AT 02:52 PM (CST)[/font][p]Its is cheaper to go to the 700R4 transmission.The overdrive unit can handle more horsepower but it cost twice as much as a good built 700r4 tranny.I would recommend the 4L80 for anyone that does alot of heavy towing.Research all options before you make a decision.
