so another noise raises its head lol. When putting it in drive, there is like a loudish rumbling noise coming from the shifter area. as soon as you accelerate noise gone, slow down to creeping speed noise returns, take out of gear into neutral or park and noise dissappears, could it be the drive shafts ??? gear changes are smooth as silk and no errors or hesitation

 

Have you opened the bonnet/hood and listened whilst in gear .
My money is on a crook supercharger isolator coupler .
As mine done that same thing just before it failed .
You can easerly check by removing the belt and rocking the blower pulley
back and forth to check for unsprung free play .

If the noise continues in drive with out moving , that rules out driveshafts .

 

new coupler and oil fitted less than 10 months ago. no sound when driving, only idling or when stopped, torque converter perhaps?
