Swapping 6hp21 into a pre LCI e61 with 6hp19

[That_Bimmer123 3]

Hi all,

I Have a 06 pre lci e61 530i, I am swapping the transmission from 6hp19 (which has sh*t the bed) to a 6hp21 from an lci 530i. Unfortunately 6hp21 isn't a straight swap for pre lci cars with Msv70 and 6hp19, I already have the transmission with a n52 engine, full harness, msv80 ecu cas and keys from the same donor car and lci throttle body, plan to get lci MAF, what else am I missing ?, have read up a lot of e9x transmission swaps on forums and I imagine it should be similar for e61 but still would like to hear any recommendations of things I might need.

so far I have:

- 6hp21

- MSV80 ecu , cas and keys

- Lci Throttle body

Also the plan is to swap in the cas and msv80 which i will have to swap some pins around once i go through the wiring diagrams for both lci and pre lci e60s and bolt in the new transmission then go from there i will also have to code some other modules like DSC using bmw standard tools later on, would love to hear from somone who attempted this before or experince with a similar swap to guide me on what else i need to complete this swap.
