5HP24 / 5HP30 thoughts...
 

Requesting input on the 5HP24/5HP30 compatibility as it relates to the 4.6iS:

- Focusing on ZF 1055000040 Transmission (latest 5HP30 out of 01/95-02/02 E38 750i)
- Electronics & valve body seem swappable between ZF 105800003434 (4.6iS) and above. If not, difference between GS flashes? Flashable?
- Re-use 4.6iS bell housing/TC/Flywheel or use 03/96-01/97 E39 540i bell housing/TC/TC plate/flywheel. Upset balance of crank?

Copy and paste of details from an excel file I made follows:

Curious as to your guy's (technical) input.

What is the objective of the potential swap?

Seems like a lot of potential trouble, particularly with the electronics, to put an older transmission in.

The objective is higher input torque threshold. Don't get me wrong, I'm (still) all for utilizing what's already installed. Haven't found much technical info on 5HP24 strengthening methods. (Although, I have found places that will sell you a "built" 5HP24.)

Currently, the most solid data I've found to meet the objective is steering me to the 5HP30. (This is not to say it can even be done for a reasonable $$/time/effort.) So, I'm seeking input....

edit: need to do more homework, specifically:

GS8.60.2 flash vs. GS8.60.3 flash
Physical/Electrical differences between harness/valve body/sensors

edit2: hearing through the grapevine that Ron @ Performing Imports had beefed up a 5HP24 for his E38. Might be a good idea to draft/send an e-mail his way, and hope that information might be shared.
