twistedfocus1647545489 Posted June 6, 2007 Report Share Posted June 6, 2007 Does anyone have, or know where (local) to purchase the speedo gear you need when changing ring and pinion? I need a 373 one for manual trans and and 355 one for auto If your drive gear inside the trans is a 7-Tooth (most common), you'll need a 21-tooth driven gear for 3.73/T-5. I always went to Ford dealers for them. The 21-tooth is red. The AOD probably has a 7-Tooth drive gears as well, but it may be 8. Normally it's best to check them first because an 8 tooth drive gear will require a different driven tooth count. If it's a 7-Tooth also, it will need a 20-Tooth driven (Black). If it's an 8-Tooth driven, a 21 will be close, but not exactly right. I can get you part numbers if your dealer has trouble finding them. Link to comment Share on other sites More sharing options...
Martin Posted June 8, 2007 Report Share Posted June 8, 2007 i have what u need for the 3.73. ill charge u the price i paid. i bought them knowing my speedometer was off and then i went to change it and the guy before me already did the driven gear but not the ring one. i have the correct set-up. Ill have to find it but i did my research and it would fully recalibrate your speedometer and it would do it right. not half ass. im just going to tune my car Link to comment Share on other sites More sharing options...
