DIY: Transmission and Differential fluid replacement

If you have all the proper tools (socket sizes, pump to pump oils to the case since it is hard to reach the fill plugs), maybe an hour-hour/half to do both. Honestly takes more time to jack up the car and throw it on stands than it does to crack the plugs open and drain.

Well, did this yesterday with Bladecutter. Went pretty good other than the part where you try to find a shop that carries redline, or any rx8 compatible, tranny fluid. Ended up going with the Ford Dealer Fluid, See how it goes, got to read some more reviews on it. Rumor has it its good stuff though. Used Lucas diff fluid in the rear, any complaints about lucas fluid?

An easy upgrade to the process.
One of the electric extractor pumps, I got mine on ebay for about $40. I just swap the feed and suck lines and pump from the bottle to wherever it needs to go.
It is the one in this video http://www.youtube.com/watch?v=MtUZHT99owo
I did the 8, and did my ford ranger yesterday. Very Very simple. I even used it to suck the rear dif oil out of the ranger.
Only thing is that it will foam the oil if air gets into the feed. Just give everything about 5 minutes to set, and the bubbles go away, then top off.
Makes an oil change on the 8 a piece of cake too.

I don't have much time to read through all 16 pages right now but I think I made a mistake. I went and got 4 quarts of mobil 1 75w90. The RP was $19 each!! I think I shouldn't have gotten 4 of the same right? What I got will work for the diff? I should get something else for the trans? I'm doing my clutch Tuesday and decided this would be a logical and easy thing to do while I'm under there.

You can just return two qts of 75w90 in exchange for 2 qts of MT90 for the transmission.

Before the BHR guys say it, Eneos GL5 works great in the trans. It is probably best to stick to Redline, Eneos, or OEM, as the tranny seems more sensitive to the specific formulation than to what specifications a fluid meets.

Sonuvabi$@"! Why does this have to be so freaking stupid. I'm so sick of all the specifics this damn machine needs. I love the car but really this is getting ridiculous. We didn't but $180,000 supercars. I'm not paying $19 per quart for a damn fluid.

I know what you mean, but that is just getting to be how it is with cars. Just look at all the extended drain coolants with incompatible formulations. I also had to run all over to find the "right" Dexron III for a T56. The RX8 is a particularly odd-duck, but it is just the direction cars are going.

Screw it. I'm going back to my 87 fiero. Quick, light, good on gas, reliable(ish) and I could probably just **** in the transmission and it'll be perfectly happy. (forget the catching on fire that fieros tend to do.)
What brand of oil do you refer too

Screw it. I did my clutch yesterday and a bunch leaked out so I had to put something in. Didn't have time to get redline so I just put in RP 75w90 and it seems to be ok. I'll change out the diff oil next week. I too used one of those marine oil hand pumps. Car was on a lift so I set a ladder under it and placed the bottle on that and just pumped away. Took all of both bottles with a bit leaking out. Feels quieter but still has some issues getting to reverse. Oh well.
