It is very likely that you'll see more failure on the 3.0i. The reason for that is not due to whether it's the GM or ZF box, but because over 70% of X5 sold in the US are 3.0i compared to 30%, which includes the 4.4i, 4.6iS, and 4.8iS. So, if you associate GM boxes with 3.0i and ZF boxes with 4.4i, 4.6iS, 4.8iS; then the odd of the GM box failing is over 2 to 1 compared with the ZF box.
