Flux - I wouldn't be worried about an Agile 4wd. I haven't seen anything anywhere hinting that they don't do a good job and from what I hear the ride is amazing for such a short amount of lift.
Brianjwilson - Noted! That could be a lot of fun.
BoyWonder - It would ultimately mean you would need to purchase a new driveline. Hopefully yours already has the correct rear driveline on it and you dont have to worry about it but If it looks like mine then I doubt it.
I also had to borrow some nuts I had from a different ford part to use on the bottom of the new transmission mount because the ones they had on the mount installed wouldn't work so make sure you get a couple before you go trying to install it because thats frustrating. The nuts that attach to the bottom of the tranny mount are the same as the ones that hold the tranny crossmember onto the frame.
Also before you go jacking the tranny up so you can slide the mount underneath, there are two tabs on the transfer case housing that need to be either ground down a little bit or cut just the tip off. They barely touch the body (on the top) and the gas tank (on the left side) and it creates a hell of a noise when they do.
Here is a picture of the one on the top...
Here is the one on the Left (drivers) side...
The tabs are there to work with a tool that will help separate the transfer case housing. There is still a tab located on the lower right side that could be used if you do cut too much off of these two but really only the tops of the tabs need to be taken down. You could probably even just use a file and some elbow grease to get them down enough but I just went extreme and chopped them with an angle grinder cutting wheel. Kind of over kill really now that I think about it.
Heres how i did it.
1. Place jack under the tranny right in front of the transmission crossmember and then place a 4x4 block of wood on top of it, lift the jack to support the weight of the transmission.
2. Remove the bottom two nuts on the transmission mount that attach it to the crossmember.
3. Remove bolts on the sides of the frame holding the transmission crossmember on (19mm) and remove it. (one of my nuts on the one side was stripped so I didnt get to fully remove it but it still worked)
4. Replace the incorrect transmission mount thats too short and should have never been put there in the first place with the correct one by removing the two bolts holding it onto the tranny (19mm).
5. Lower transmission as carefully as you can (if need be) only far enough to gain access to the top of the transfer case to grind off some of that tab and the one on the left if it hits the gas tank.
6. Jack up tranny and re attach the transmission crossmember.
7. Attach tranny mount to tranny crossmember with the two nuts that you already bought at the ford dealer/hardware store.
8. Sit back and think about how you now need to consider buying a new rear driveshaft when you would rather spend the money on your interior.
BE ADVISED! Moving the tranny up and down thats still attached to the engine could affect the exhaust where its mounted to the manifolds. It may not be a bad idea to loosen the exhaust bolts from the manifolds before doing all of this to ensure nothing gets twisted funny and then is a pain to re align on the manifold. Also check to make sure that lifting the tranny up isn't going to interfere with your exhaust when your done if it crosses over in that area.
Hopefully that all made sense. Feel free to ask any questions.
