Metal Filings In T56 Gearbox Oil

[WBT56]

.... From memory it is poping out as I let the clutch out and going down from 3 to 2, but this has only been occuring after the car has been driven a fair bit. I.e, today I did 2 trips of about 20km with no problems at all, but the other day after a lot of stop start driving it was regularly (maybe 1 in 5 shifts) jumping out. So, your recommendation is to fill it up with 4L of Transmax Z?

Try the transmax and also bleed the clutch fluid through till it goes clean. A heat related problem may be that you are getting clutch drag when the car is hot, and the double bump this induces in the shift is causing you to not fully engage second. (If it jumps out as soon as you let the clutch out, this indicates either not fully selected (intermittant fault) or outright damage to gear/hub dogs.(generally permanant fault)). Ben.
