cholag Posted July 22, 2008 Share Posted July 22, 2008 I have a 1983 ZXT that had a auto trans, but I found a t5 in the junk yard, so I had pulled that and now I am rebuilding it. But I was wondering, to make the speedometer work do I need the speedometer gear out of my auto trans, or will the speedometer gear in the t5 work with my existing speedometer cable?

VinhZXT Posted July 25, 2008 Share Posted July 25, 2008 You don't have to change the speedo gear since both cars have the same gear ratio in the rear end. Quote Link to comment Share on other sites More sharing options...
cholag Posted July 26, 2008 Author Share Posted July 26, 2008 But I thought the autos came with an R180 and the 5speeds came with a R200? Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted July 26, 2008 Share Posted July 26, 2008 you're only changing the TRANSMISSION, which is a totally different part from the DIFFERENTIAL. the speedo gear is only dependent on which rear end you're using. not the transmission. oh, also r180/r200 doesn't matter. only the actual gear ratios inside (that is, if you're changing your diff as well as your transmission) Quote Link to comment Share on other sites More sharing options...
