I assume you have a 3 speed manual transmission. This is the proceedure we followed to remove the transmission from our old 550. First remove the feederhouse. This gives you a lot more room to work with. Next you need to remove the driveshafts. Removing the driveshafts is a 2 man job. On the engine side, safely jack and block up the combine and remove the tire. Next the final drive has to be pulled off to remove the driveshaft. To move the final drive, take a piece of iron about 3 feet long and drill 2 holes in it to line up with 2 bolts that hold the two halves of the final drive together. This iron will act as a handle to hold onto the final drive. Once the driveshafts are removed, bolt the final drive and tire back on and repeat this process on the cab side, but once the driveshaft is removed, leave the tire off as this gives you more room to work with. loosen the transmission to be able to remove the lower drive belt. Remove the clutch, shift lever, and anything else connected to the transmission. To remove the transmission from the combine, remove 2 bolts from the casing of the transmission and bolt on a piece of chain. Hook a comealong to the chain and gently lower the transmission to the ground. For added security, place an old tire underneath while lowering in case the transmission falls down suddenly. I don't quite remember exactly were we secured the comealong, but it was on a heavy piece of iron near_in the engine compartment. I hope this helps you some. By the 3rd time we removed the transmission from our 550, we had this removal process down to about 3 hours from start to finish. Good luck.
