first thought is to recheck the shift linkage on the side of the transmission. Make sure something didn't get bent or tweaked during the engine swap.
I had one do this in reverse once. For us, that meant time for a new reman (we don't do much in shop transmission work.)

| I agree, linkage. You say it works in reverse but how does it feel when your shifting it into reverse? Does it feel like it normally feels? |

| I would remove linkage and manually move the shaft going into the transmission (leave the lever on the shaft). See if it moves smoothly and hits all the detents. If everything moves well try having someone (you trust) start the bus and hold their foot on the brake while you manually put it in gear from the transmission without the linkage hooked up. Please be extremely careful when doing this, this would be what you call VERY dangerous. This would be my course of action before I took it in to be diagnosed or pulled and replaced the trans. This is the end of my expertise but there are others here that are well versed in diagnosing these things. |

| It's more than likely your Torque converter and the overrunning clutch in it has piled up. I have had a number of them do this. |

| Call Ralph Lair @ Indland Truck, 1-800-362-2970. He should be able to offer some insight. Ralph has been my "go to" guy for years. Like you, I'm mostly R&R on these units. |
