Anyone replaced a torque converter?

Ironically, none of the AWD BMWs used 4HP transmissions. It was only in their RWD drive cars (and AFAIK, they still have never made a FWD car). The output of the 4HP22/4HP24 drove a transfer case in the case of Land Rover, or a driveshaft in the case of BMW (and many others). For this reason there may be differences in a rebuild kit but the transmissions themselves are the same. If you're looking to replace your trans then I would follow Extinct's advice, I don't know that the bellhousing would be the same if you tried to wedge a BMW trans in there. I think that level of difference might get down to the part number level as opposed to the series of transmission. It might be worth exploring from a rebuild perspective if there is a large cost advantage.

@ahab the thought behind the beamer was to use the BMW rebuild kit b/c it's half the price of the LR one - I doubt the trans itself would be a one-for-one swap
My questions are:
- Are the bolt patterns the same on the 24 as on the 22?
- Can my ECU run the 24?
I use the center dif lock occasionally and would not want to lose this feature so it would need to be an 04 trans. I also hear that the dif gearing is slightly different in 03-04, but I guess it's taken up in the transfer case.

If you are going the route of a TC, I know your in WA, there is a shop in NJ that rebuilt the torque converter on my 740, a while back. It was a cheaper, better option than sourcing a new one, or risking a used one. There were some national companies that you could ship to if cared to look around.

I know it might sound insane, but with a used TC costing $100 i'm ok dropping out the TCase and trans if it breaks again. I'm only rebuilding the trans this time round, so next time i have to do this, I'll rebuild the t-case
