i use neo synthetic on my transmission and differential. here is a site you can get it from

here are some instructions to do your tranny and differential oil.

The diff is easy the transmission is tricky. First I went to Home Depot and got 8 Ft of 5/8th od dia clear tubing and a plastic funnel set. That's how you get the oil in the transmission and differential. Now, make sure you have 3 new aluminum washers for the large transmission drain plug, the differential fill plug and differential drain plug before you start. I get mine from the dealer. I don't like using the copper ones that the parts stores usually carry because, at least here at the beach, galvanic corrosion (from dissimilar metals) can be a problem. Make sure you have a tube of liquid Teflon thread sealant for the small transmission drain plug and the transmission fill plug (also at Home Depot, or you can get the fancy automotive stuff at the parts store). You also need a few large metric combination wrenches and sockets I can't remember the exact sizes but I think they were ~22-25mm. Finally you need 3 quarts of oil for the transmission and 2 quarts for the differential. I used Redline MTL for the tranny and Redline 75-W90 for the diff.
The differential is easy the plugs are in the back, undo the fill plug then undo the drain plug. Put the new washers on the plugs, and put the drain back in. Stuff one end of the hose into the differential fill hole, push the funnel onto the other end of the hose. Stand up next to the rear of the car while holding the funnel. Slowly pour in the oil until it just begins to spill out of the fill hole. As a side note, the car should be completely level while doing all filling operations.
Now for the transmission, there are two drain plugs, one fill plug and one plug that you don't touch. First remove the sheet aluminum cover and set it aside. On the bottom of the transmission case is an obvious big drain plug. The other three plugs are on the driver's side of the transmission. The highest one has a recessed square socket don't touch it. Approximately below it is a plug with a protruding square socket, this is the fill plug. Behind and a little below the fill plug is another protruding square socket plug, this is the second drain plug. Remove the fill plug then the big drain plug let the oil run out. Then remove the second drain plug. You remove the fill plug first other wise the oil "plops" out everywhere except in your drain pan (you did remember to put a pan under the drain plug :).To fill the trans put the new washer on the big drain plug and the sealant on the second drain plug and put them back in. Stuff the funnel in one end of the hose and ~3" of the hose in the fill hole (it just barely fits) stand up next to the car while holding the funnel and slowly pour in the oil until it just starts to spill out.

hope this helps

Dude

Read the FAQ thread that is STICKIED in this forum. Lots of good info in there about stuff like this.

+1 to the Neo, when I changed my fluid it truly does elminate the cold notchy shifts. Best stuff ever =) 1 gallon jug will be enough for the tranny and diff.

Get a "Drill pump" from Home Depot (in the plumbing department). It's $7, you'll also need 2 garden hose to nipple adapters (which are $7 each!) but you'll have a nice pump for the oil (and any other fluid) for ~$20. The pump has a drive axle that fits in any drill and the drill does all the work.

+2 for Neo... I'm about to give royal purple a shot in the tranny just for the hell of it(it's all I could find local here).

Might have to check that out!

i used some of motuls gear oil 75w-90 works really well for me.
