Hello, Question? I bought this old road grader (allis chamlers ad-40)and this is the problem. Only two forward gears and 6 reverse gears. And those two forward gears are really slow! It has two sticks, The stick coming from the transfer case side has a low and high. The other stick which comes out of the transmission has 3 reverse and one forward gear. I think it should be 3 forward and one reverse gear. I think some thing has been changed for what ever reason.. The engine rotation is clockwise looking from the fan side. but the rotation coming out of transfer case (towards the rear axle side) is counter clockwise. not sure if this is right or wrong. A guy I talked to here said he ran one and it had 6 forward and two reverse gears. I do not want to tear into it to find the problem unless that is my only choice. Any help I would be thankful for. Joel
