Is it possible to date a gearbox from the numbers stamped on the front left hand side EG FAXe****.
There is no exact way of dating a gearbox. The gearbox number was not directly attributed to the engine number and the power plants were not fitted in any particular order.
Having said that I have over a dozen FAXe photos and they range from FAXe 1082 to FAXe 4308 but the actual number would be much higher. Some people have boxes with blank serial number pads.
You could try and average out the numbers over the 2 1/2 year period the 9FXEY power plants were used in the MK1S, MK2S and GT. The 9FXEY engines used were numbered from around 51000 to 56400.
I have one example that may help. Car 2031 has engine 9FXEY 55494 and is fitted with gearbox FAXe 4253. But I can't confirm the gearbox is original.
Sorry I can't be of more help.
