Once I get my 40 back on the road and make sure my just rebuilt transmission is good to go, you can have my old H-42 four speed one if you want. One of the bearings was just starting to make a little noise, but otherwise it ran fine. You might be able to swap out the bearing without going inside, depending on which bearing it is. I might even have a good used bearing that would work. How's that for a "decent" (but not perfect) 4-speed transmission? And it fits in your current budget!
