Surplus Humvee Build - Transmission Maintenance How To | 05

In this how-to repair video I'll go over replacing the 4L80E transmission filter in this M1097A2 HMMWV (Humvee) or any other A2 truck. Along the way I'll find out what surprises aren't listed in the service manual (TM 9-2320-280-20). And since I'm under the truck anyway, I'll cover replacement of the diesel fuel lines and tank check valves.

This is part 5 of the video series documenting the steps to repair this Army surplus truck purchased from GovPlanet and get it back on the road as a civilian truck.
