Looked up an '08 g5 - but no matter the year the torque spec should be the same

Engine Mount
Tighten the nuts in the sequence shown to 100 Y (74 lb ft)
Tighten the bolts in the sequence shown to 50 Y (37 lb ft) middle - left - right

Rear Trans Mount - Upper
Tighten the bolts to 60 Y (44 lb ft) - bottom 3 through sub frame
Tighten the thru bolt to 100 Y (74 lb ft) - on cradle

Front Trans Mount - Lower
Tighten the bolts to 90 Y (66 lb ft) - on trans
Tighten the thru bolt to 100 Y (74 lb ft) - on cradle

Dont forget to always hand start the bolts - The mounts need to settle so after everything is installed loosen the thru bolts on both trans mounts and tighten the rear trans mount first then do the front mount - or 3 ugauga with the impact - german spec lol
