Your version of the 5HP24 (of which there are 27 in total) is the ‘029’ model (i.e. ZF model number 1058 000 029)



The rear end of the transmission is designed specifically to accommodate the NV125 transfer case



The only other model that would fit your E53 is the ‘034’ model for the 4.6is but this is a ‘heavier duty’ version with a larger (280mm) torque converter and an additional plate in the D-clutch pack, as well as a modified upper valve block (identified by the numbers ‘075’ stamped on it)
