34-200-8.1-FG - TRANSMISSION, 8.1 STRIPPED 4FG

Includes pinned couplers already pressed on the transmission shaft.  If the original transmission you are replacing is from a 2010 - 2011 HD or HDI with the 34-200-FG transmission model that does not have a pinned coupler on the output shaft you will need to either reuse your couplers from your old transmission or order (2) 34-239 couplers in addition to this transmission.  Check your couplers splines for wear before ordering.


Starting with the model year 2012 the dealer could choose through a factory option what transmission ratio they wanted to be installed on some of the below models. You could either get the standard 6.4 or 8.4 low gear ratio.  The low gear is best for use with tracks and heavy loads.  In the model year, 2017 Argo revised the ratio to 8.1 replacing the 8.4 for better performance with tracks and turning in deep mud.

Note:

To determine what gear ratio transmission you have on your above model, open the hood and look to the left of the red oil fill breather tube on the transmission.  Next to the serial number, it will either have a 6.1, 6.4, 8.1 or 8.4 stamped in the case.  If there is only the serial number and no additional numbers you have a 6.4.  If it shows 6.4 you need to order the 34-200-6.1 transmission,  if it shows 8.1 or 8.4 you need to order 34-200-8.1 as the 8.4 version is discontinued.
