gearbox noise!
 

hi have noticed a new noise from my gearbox :( when backing off from power is grating noise but is fine when you put your foot down no noise but happens when you back off and is braking through each gear car is 98 uk turbo and have only noticed it since upping the power after remap,any one had same prob and what was the cause

Is it in every gear??

:confused: sounds like it more noticable i 2nd and 3rd and 4th not real metal on metal noise but more of a whirring grinding noise only noticed since i rebuilt engine thought could be clutch release bearing? but really dont know!

anyone!!

Does it change with road speed or engine speed (revs)?? A noise that changes with engine speed will indicate a problem on the input side or in the box and a noise that increases with road speed will indicate a problem on the output side or one of the diff's.. Or even a wheel bearing..

noise appears to not get worse at speed or with engine revs just stays the same :brickwall

anyone!
