Some of the earlier units had a problem with the oil tubes splitting and then you loose a clutch..

You'd be better off getting a Deere manual.. but here goes.. Drain the transmission..plug in the rear center of the transmission .. theres close to 20 gallons in there ..so be prepared.. Remove the rear cover so you can look in there and have an idea what your doing in preparation for transmission removal. Hopefully you're doing this for a reason other than speculation.. crawl under the machine.. on either side under the steering clutches, are threaded plugs. remove these plugs and covered by these plugs you'll see an allen headed bolt. Screw these up till they contact the steering clutches. this will support them when you remove the shafts that connect the transmission with the steering clutches. I dont remember if a 450G has a double reduction final drive or not..I'm thinking it does . If not you'll have to break one track and remove one sprocket. If there is a triangular shaped cover visible on the side of a final drive, forward of the sprocket then youre in luck and dont have to break a track. Remove one of these covers and remove the shaft that joins the steering clutch to the final drive. Look in the hole and you'll see the other shaft that has to be removed. It connects the transmission output to the steering clutch. You can make a tool with a bolt welded to a 3 foot rod. I forget the thread size.(theres a threaded hole in the center of the shaft). or you can reach in from the back..barely . and move the shaft outward and then out thru the side where you remeoved the first shaft. After thats out, slide the same shaft from the other side into the center of the transmission assembly . This will allow the transmission assembly to slide out in a little bit.. then remove the small bolts that clamp the hydraulic tubes into the manifold on the top rear area of the transmission housing. Remove the retaining bolts that hold the transmission assembly into the case. DO NOT remove the bolts and large flat washers that are at the end of the long rods on the bottom of the transmission assembly. There are 2 of them. Remove them later after the assembly is slid out of the housing. This is from memory , so hopefully its all there.. now pry the transmission assembly backwards out of the housing .. All the way out to the ends of those rods I mentioned.. it looks like the weight will snap them off ... but no worries... they wont break.. its heavy so it will take a little bull work.. when its all the way out , you'll need something to pick it up and slide it the rest of the way off those rods.. Then disassemble as needed... then you'll really need a book... Sounds like a big deal... but I've removed the transmission assembly on these in a little over an hour..
