# TRK-402 - ARGO TRANSMISSION REBUILD KIT, ADMIRAL (2010+)

TRK-402 - ARGO TRANSMISSION REBUILD KIT, ADMIRAL (2010+) - AURORA, AVENGER ST, HD, HDI - ARGO PARTS  
  
Transmission rebuild kit with all bearings, bushings, snap rings, and seals to rebuild the Admiral transmissions external and internals on Admiral transmission models 34-200, 34-200-6.1, 34-200-6.2, 34-200-7, 34-200-7.1, 34-200-8.1, 34-200-8.4, and 34-200-AR2.  
  
**Please note that the parts list shown in the product downloads is for transmission versions 2016 and newer.  While the bearings, snap rings, bushings, and seals have not changed from 2010 to current, many of the gears and assemblies have so be sure to call us if you have a 2015 or older model and need gears or other components inside the transmission as you may need to replace sub-assemblies to get select gears to work in older transmissions.**  
  
**This kit comes with the new input shaft seal that was released in 2026 to stop oil weeping from the bearing and is not shown in the current Argo parts manuals. Also included are the updated planet gear bolts and tabs to prevent the bolts from loosening under torque and heat.  Be sure to red loctite them when installing.**  
  
**Reference the Product download PDF for parts included in the kit.  Kit comes with the factory recommended Loctite 598 gasket maker.**
