You'll need a good shop press, a bearing splitter, and a gear puller with LONG arms on it.  At work I use the Toyota SST and it has special adaptors for W, R, G, etc... series trannies.  It can be done with simpler tools, but the  right stuff really makes it go smooth.  I've rebuilt several, and wouldn't really want to do it without the right tools...

The splitter (sometimes called a bearing separator) and puller can be rented at most rental shops. The press can be replaced with careful use of a brass drift and hammer. When I rebuilt the tranny on my Explorer I took a ton of digitial pics, which really helped when I put it all back together. The only trouble I had was I did not orient the key channels on the sliders with the keys on the inners. Really, there is no magic to it. I used flat pieces of cardboard and labeled each one, like "First/Third", using baggies for the smaller parts, so I wouldn't get any of the components mixed up. It sat on my counter that way for at least a week, and I was still able to get it back together, even though I had never tried something even close to it before. I was too dumb to rent a bearing separator, instead using a mix of cold chisels and screwdrivers...DUMB OF ME. Big risk of dorking op the bearings. Also, you do not want to try to pull the bearings with a puller if you plan on reusing them, because the jaws will bend the outer cage on them.

The G54 is one of the easiest trans to rebuild.
To rebuild it without a bearing splitter, press, and feeler gauges would end up chipping gears and deforming the end of shafts.
Please do not use a hammer and beat on the gears, shafts, ect

If you want to do it yourself, get a factory service manual from e-bay, and plan on spending time learing how to do it.

Above all else, get it clean inside and out, and take special care to check for mainshaft, and 5th gear endplay.
Toyota sells oversize c-clips to properly complete the job.
Attention to the details will ensure a lasting job.

I spend about 6 hours to go complety thur the G trans.
