I have a TH400 from a Jeep Wagoneer that is the Chevy bolt pattern. Lots of the Jeeps used a TH400 with the AMC bolt pattern, but this one is not. It has an adapter to go to an AMC360. The owner I got the jeep from told me that the low 25,000 miles on the odometer are original. I actually drove this jeep around the neigborhood to make sure the transmission worked. It shifts through all gears with no problems. The transfercase is a Dana 20, Gear Driven, Not Chain. I hear the Dana 20 transfer cases are very strong. There is no chain to stretch. I dont have a torque converter for this unless the jeep TC will work on it. I dont know too much about auto transmissions just that this is a very nice and clean unit. Please email me with any questions and Ill try to answer them to the best of my knowledge. I can email pics if interested just drop me a line at dmons_soul@yahoo.com Thanks
