eh??
no it does'nt...
g'box mount is lift it up a bit off OPE mount, drop in new one and lower it down. Front is fiddly (access to bolts etc) need to support motor, again jack it up remove/refit, and rear is same again.. lift it up & possibly removed rear mount off block (x4 bolts only)
not a g'box out job, unless that was being done for another job like clutch etc
