HOrnbrod Posted June 16, 2007 Share Posted June 16, 2007 Have regeared and put on bigger tires; my speedo now reads about 8MPH low. 91 MJ, AW-4, 2WD, electronic speedometer. Do I have a speedo gear I can change out to correct the speedo error? If so, WTF is it? I can't even find it in my FSM. Damn sure isn't on the transfer case since I don't have one. Thanks.........

DirtyComanche Posted June 16, 2007 Share Posted June 16, 2007 It's be in the tailhousing of your tranny. They use the same gears as the tcase would, AFIK. Find where the speedo-cable runs into the tailhousing on your tranny, and undo it. There will also be another retaining bolt there. Pull it. The speedo gear will come out. I dunno where they cover it in the manual. Link to comment Share on other sites More sharing options...
HOrnbrod Posted June 16, 2007 Author Share Posted June 16, 2007 Thanks Dirty, but no speedo cable, it's electronic. Been through my AW-4 manual too, can't find it. Got to be a gear driven magnetic pickup somewhere, most likely on the tranny............... Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 16, 2007 Share Posted June 16, 2007 Oh hell, I thought the electrical ones used the same gear setup... Maybe no. I still think it's on the tailshaft. Looky for some wires? Link to comment Share on other sites More sharing options...
HOrnbrod Posted June 16, 2007 Author Share Posted June 16, 2007 Yeah, it's got to be somewhere on the tranny. Will crawl under tomorrow. Just was hoping someone ran into this before. Link to comment Share on other sites More sharing options...
tjbliley Posted June 16, 2007 Share Posted June 16, 2007 It is on the tailshaft area. I just did the 2-4 swap and used my same speedo gear in the t-case. the hole is there. it just goes to a small plug and then wires run along the top of the tranny to the harness.

HOrnbrod Posted June 17, 2007 Author Share Posted June 17, 2007 Found it, pulled it, 34 teeth. Need a 37 or 38 tooth, according to various tables and calculations. Have verified the speedo reads about 8-9 MPH low, and got a ticket Thursday night. :mad: The cop wouldn't listen, pure redneck 'Bama a-hole. However he did give me a pic from his daughter's wedding reception: Link to comment Share on other sites More sharing options...
