Technical
You will need to use the starter ring gear from the L322 / BMW X5 diesel like THIS , otherwise you can’t fit the flex plate bolts.
If using the P38, 4.0 medium diameter converter you can use either the 4HP22 or the 4HP24.
If using the P38, GEMS 4.6 large diameter converter you must use the 4HP24.
The 20mm adapter plate and the V8 autobox work out the same length as the P38 diesel box so no changes to propshafts or mounts are required.
We can supply any combination of hydraulic or electronic 4HP22 or 24 to suit your vehicle, if electronic and not in a P38 you can control it with a Compushift
