Thread: Autobox swap

Agreed that was a typo.. 85 indeed.
Thanks for the info, that was the info i was searching for. Ibwill give that a go

I recall reading about a P6B owner that modded a BMW autobox with some parts out of a LR autobox. I'd saved the link, and just found it.
Interesting read .. but then again I'm a P6 fanboi and like the idea of frankenworks mods like this ... hence the interest in the article.

Some points to note from having skimmed it again now. There are some differences in the boxes, not insurmountable, but points to note in the article.
Like the author has said, you may have to change the governor that controls the shift points .. ie. disassemble/reassemble internals .. not just swap out external housings.
I've had experience with high revving, zero low down torque, 323/325 BMs back in the day and the shift points are way way different to how a V8 with low down torque delivers is power.

I know the box has many similarities, can't remember exactly but the BM sump isn't so deep(but, obviously an easy swap over) ... I'd be thinking the major differences would be in both input and output shafts almost for sure.

If you have the BM box there can you check something ... my nephew likes to dabble in BM parts, and he had a 4HP22 out of a 323 he was getting rid of. I asked him to take photo of the dip stick for me. I can't remember( I must have deleted the photo??) but I think on the BM it's on the LH/passenger side, where on the LR(D1 era) it's on the RH/drivers side.
Not a problem in your situation, but I'm more interested in this for the D2(which don't have dipstick/filler tubes!) .. issues on the TD5 D2 is that it's so damned cluttered on the drivers side already, it'll be messy to get it fitted nicely/easily there. But as I said before, I also recall that the BM sump is not as deep(not ideal) in a D2.
