Thanks mate
Wiki puts it pretty simply: 'CAN bus (controller area network) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle'. It is like having a computer network instead of a load of stand alone PCs.
I thought the first video was good and the presenter held my attention. The second was more on topic but the guy was boring. I struggled through 13 minutes and then noticed the video was an HOUR and 13 minutes! But I'd had enough by then.
I can probably bore for England about auto boxes. But at least I try to keep my answers short and to the point. Not saying it always works :-)

Thanks mate
Update on No forwards / strong reverse.
A/C clutch drum clip fingers are broken. All 15 missing fingers accounted for. Clutch packs do no seem that bad. Will upload photos of damage as soon as I get fresh cells for my digital camera.
On my 5hp19 it was all the fingers on the dg clutch drum and was available aftermarket on ebay redesigned. I didn't know the 5hp30 had a similar problem.
Take no pleasure in being right first time :-( Surprised you didn't find any bits in the pan. A/C on the 5HP30 and D/G on the 5HP18/19 are essentially the same design so perhaps it is not surprising they both fail. IIRC, the 5HP18 and 19 share the same part number. I think the actual issue on all of them is pressure regulation.

I found a 5hp30 at the scrap yard. It is from a 97 or 98 740. My question is that if I get this trans, with trans controller, will it 'fit'? I'm thinking the differences would be the minimal. I'm not sure since it is a 5hp30 that they would change much. Any thoughts or opinions / ideas?
BMW follows the serial number to establish i the trans will fit, but that one will fail the test for sure.
If connectors are the same, you may find differences in all kinds of things- if you do that I'd check everything on the input and output side, verify the ratios are the same (might not be a problem) but the e38
- had a more powerful 4.4L engine
- came with much larger diameter wheels and
- is a heavier car, so a lot 'in the box' (the entire box configuration done by ZF) ***will be different***
If you do get it and end up using it for parts, it may have some upgrade items- valve body, electronics, etc.
Beware any connector differences, they could have put the trans on CANbus for all I know (unlikely, but e38 was the first BMW with CANbus, which is why so many people can't figure out the electronics!)

Thanks. I will have to verify the year of the possible replacement. I've been searching all day to verify things prior to going forwards with the swap. I would much rather have a 5hp30 from the same rev. Well, I would rather be able to buy the a/c drum at a good price, but we all know that's not going to happen. I plan on doing lots of research, cross ref parts, and check multiple forums to see if anyone has done something similar (sure I'm not the first). I am worried about the CANbus too. Wish I had some more options. Not do searching yet. I am not 100% sold on doing the swap yet but think it would not be too bad. Worse case would need to change out the tail shaft
Well, off to perform more research. Thanks to everyone for your help!

As genphreak says, keep it simple. If you want plug and play, pick another gearbox with the same ZF number as yours. It will end in 010 or 029 from an E34 or E32. Details are in the spare parts catalogue:
www.e38.org/5HP30%20spare%20parts%20catalog.pdf
Of course, unless you inspect it, you are not going to know if a 'new' used box is any better than your own

What if it does infact go forward in manual/winter mode? Mean it's just the VB issue?
