Hi everyone

My gearbox has been whining for quite a while now, it used to be in 3rd gear only but now it’s pretty much any of the gear’s except 6th.
Only does it when I let off the gas, never does it on power.

would a box from a Cupra R Fit or any other petrol 6 speed car like the golf or does it have to be an AUQ engine car?
Thank you in advance

Have you fitted the shim mod? that fixes it in most cases and you don't even have to remove the box from the car. Note there are 2 different sizes, you need to measure the one on your box to see which one it is.

my car had the whining gearbox a couple years back when my mate had it, was fine going up the gears but as soon as you let off throttle it would whine very loud, I pointed him in the direction of the shim, he ordered it and fitted himself in about 30 mins with no mechanical knowledge, cured the whine and its still perfect now with me.

Perfect I’ll give it a go, it’s going in for mot and service this week so I’ll get the bits measured up and ordered. Hopefully it fixes the problem. Thank you sir
