Guest greimann Posted October 25, 2002 Share Posted October 25, 2002 I'm guessing that english is not your first language, so let me see if we can translate and help out. Originally posted by mykazuo:I have a problem with my speedometer. I have a 25 tooth gear but it has failed. I went to the parts shop but all I got was a 22 tooth gear (The highest number they have) and now the speedometer shows double. 20mph comes out 40mph. Where can I get a 27 or 28 tooth gear? I think you will need to change the drive gear as well as the driven gear to get the correct ratio. This will require removing the tailshaft housing of the transmission. These parts are available at the dealer. This web site will help you determine which pair you will need. http://www.tciauto.com/tech_info/speedo_gears.htm Quote Link to comment Share on other sites More sharing options...
