tranny and rearend fluids

This weekend I am planning on replacing the transmission fluid and the gear oil in the rear end. Is there any specific weight of oil, brand, etc. that anybody recommends I use for this? I assume for the rearend the Mobile1 synthetic gear oil will be fine, I have no idea about what to put in a transmission though.
thanks

in all of my rotary vehicles, I've loved redline oil's line.
for the manual trans. MT90. for the diff. redline 75w90. no complaints and a lot smoother. great reliability and preventative maintenance upgrade.

Thanks, and does anybody know approximately the capacitance of the diff and the tranny? Now that I know what to buy I need to know how much of it :)

I too, have used Redline in all my rigs. Be aware that trannys and diff's need different additives. I find that in all cases the synthetic makes shifting and cold wx running noticably easier. I suspect that Mobil one and Valvoline synth are fine, just be sure to match up the GL rating with the tranny or diff.

The Amsoil synthetic covers the requirements of both--and does an excellent job without any other additives! I'm fairly certain you could get similarly stellar results from Redline or another high-grade synthetic... Warm it all up to make it fluid by driving her around a bit, then drain from the drain plugs in their respective lower locations. When all is empty, clean those drain plugs& threads, and plug 'em back up. The color/smell/consistency and metal content of the drained fluid will tell you lots. Find the fill plugs located approx. halfway up the side of the housing in question, and proceed to pump in gear lube until it comes out of the fill hole. This is the appropriate fill level, if your REPU is parked/blocked up level; this is kinda important... Plug 'em back up, and you're done! Actual volume may be deceptively small/little. Do not be alarmed! Overfilling more than a tiny bit is not so good, either.
If your trans. is less than perfect, try the Amsoil--you'll be amazed what happens as you drive it more and more! :)

Where can I get Amsoil from? I don't recall seeing it in any of the local Checker or Pep Boys.

Only sold via Amsoil dealers...

...this might require a thorough search of your yellow/white pages... or, you might try calling the 1-800 directory and asking for a listing for Amsoil...(?)...or, try contacting Racing Beat for a referral to a dealer near you. :)
P.S.--while your at it, get some of their "Power Foam", and, if your motor's not new, give it a try as per the directions. It's great stuff, just be prepared for what comes out the exhaust when you use it! And then drive it, immediately--freeway for a while is best...

GL rating on Tranny

How do I find the GL rating requirements for the tranny? I put in Mobile1 synthetic which is GL-5 then a friend here at work mentioned something about brass syncros and GL-5 not being a good match. I have the stock 4 speed manual transmission if anybody would know what the GL rating for that is off the top of their head.
thanks
