Here's a link to the TCI site...I needed a 36 tooth which is their #882010. TCI was closed when I tried to call them so I don't know what application the gear is for, but their site seems to indicate it fits all CHrysler trannys...probably my mistake for assuming that! http://www.tciauto.com/components/speedometer_gears.htm#chry OK, the plot thickens. I have a 76 TSM and I looked up the torque command transmission in there and there are 2 applications, one for a car with a catalytic converter and one for one without. My 74 TSM only has one listed and it matches the 'with' catalytic converter application in the 76 TSM. Here is a link to a 73 TSM that uses the type of gear I purchased from TCI(the pic is on pg 13) that matches the w/o converter applictation in the 76 TSM. http://www.tocmp.com/manuals/AMC/1973/Service/Chapter7html/browser.htm Now I'm really confused. Guess I will have to try and contact both TCI and Chrysler and try to figure out what I need __________________________________________ Yahoo! DSL ? Something to write home about.
