Do you mean 643?It is an allison 634. The 545 would have been a deal breaker. At least this locks up and is 1:1 in fina. l Will probably go to 41' tires as we have 4 low
Good idea in the service shortbus! The vehicle has recieved a full service and filter change in anticipation of our journey
I have another set of filters here and will change them all again. All the bouncing around should suspend any trash and send it through the appropriate filters
This thing also has a pto hydraulic 6kw generator that i will remove and sell anyone have a need for a service truck generator?
Never heard of a 634
If it is a 643 make sure the torque converter is locking up and drive it foot to the floor until you get up to the desired speed
Does the transfer case have low range in it? What transfer case is in it and is it air shifted or lever shifted?
