Which Redline fluid did you use in your trans?
I have been using Redline ATF-D4 in my manual trans - and it works just fine. ATF-D6 can also be used. D6 is a slightly thinner fluid than D4.
When you drain your old trans fluid out... yopu keep adding new fresh fluid in the fill hole UNTIL it starts to spill out of the fill hole. THIS is why your car must be level with the ground. Perhaps your trans is low on fluid ?
For the diff.... you need a fluid extractor to "suck out" the old thick diff oil. It holds about 1.2 Liters. BMW spec's Castrol SAF-XJ (or XO)fully synthetic 75w140 GL5 diff oil. I use the SAF-XJ bc it is also good for BMW M lsd's while also ok for bmw open diff's like on our cars.
See my post #70...
DIY: manual transmission and diff fluid change

I re-used my old drain plugs. I did buy new ones, but I did not feel I needed to use a new one. Btw... these plugs weren't cheap! ~$20 each from what I remember.
Most important thing to do when changing trans fluid is open the FILL HOLE FIRST. The last thing you want to do is drain all the old fluid out and then realize you can not open the fill hole plug!! 
Btw... here is what my old manual trans fluid looked like...

Thanks for your advice and help, I thought replacing the plugs was overkill but having said that I havent removed them before to look at them and i didnt want to have the tranny fluid drained then realise i have to buy new plugs and give my local bmw dealer the opportunity to rip me a new one....
