Thanks Dave!

Ya know we got some real experts on the forum!

I for one would like us to get together and you experts could teach us less-qualified guys and gals a few things. Maybe at our jointly owned pit-property 

I for one would pay for it!

Well friend Dave, another great reference.  So glad to get those tables on torque.  I have been studying how to get my 450 ism up so i could pass that 500 of yours.  Looks like my tranny would not handle my project 

Seriously though, good info in the tables and thanks.

Just thinking,  My 1994 U300 has the 6V92 Detroit with the HT 740 Allison transmission, would anyone know if by changing out the push button electronic control panel could I gain more control over the functions and shifting points of this transmission?  Sometimes it has a mind of its' own when climbing or descending a hill.

Gerry,

Was thinking that you should have a HT746 trans. The four speed should shift four times like a five speed with the extra shift from second to lockup second. Our also seems to have a mind of it's own heading downhill, especially if starting from a stop. It sometimes coasts for a while, builds a little speed and then the engine catches up with a roar. If steep, I punch in first, make sure the engine and Jake are up to speed and then select second. I like to make sure it's in lockup second before heading down anything really steep. Have not found anything steep enough to require first heading downhill as the Jake and service brakes do the job well.

It does 57 mph in third so I usually back off the throttle when it starts to hunt between third and fourth and keep the rpm to just under 2100 or 55 mph, hit third on the pad and sit back until we get to the top.
