34-200-8.1-FG - TRANSMISSION ASM, ADMIRAL, 8.1 HT RATIO STRIPPED FG - ARGO PARTS

Admiral 8.1 Ratio (High Torque Ratio)   
  
_Used on select Aurora, Avenger ST, HDI, HD 700, and Conquest Pro XT models._  
  
Includes pinned output shaft couplers already pressed on.  If you are swapping out the transmission in a 2010-2011 HD or HDI model that does not have the pinned style couplers on your current model you will need to order **qty (2) 34-239** couplers to match up with your idler shafts.

The 8.1 ratio replaces all previous 8.4 versions.  To determine you transmission ratio look at the serial number stamped into the top of the transmission and the last digits should give you 6.4, 6.2, 7.1, 7.3, 8.1 or 8.4.  Very early model 2010-2011 versions did not have the ratio stamped as they were all 6.4 versions.  
  
You will reuse many external parts from your transmission when installing, don't discard any parts from your old transmission until the new one arrives.  
  
_\* Ships without gear lube 75w-90 Full synthetic._
