Bleeding Cooling system on M52 ( Auto )

[Ianb]

I know these are a bitch to bleed when in an e30 but I'm trying to bleed my e36 328i and am a little nervous because when i did the e30 I jacked the front really high and had to run the car at high revs for ages and all the advice i've had about the auto box is not to rev it in neutral - does anybody have any idea if reving it in neutral / park to about 2k revs will do the transmission any harm ? Thanks
