Hello.

I would like to check oil level in the gearbox.

Car Škoda Felicia 1.6 GLX, petrol, year 2000.

I am wondering if it is safe to unscrew the speedometer cable?

Is there any special procedure?

Can I expect any problems with the gear located at the end of this wire? Thanks for all advise.

I have done it in my 1.3 no problem at all,just be gently with the screw beside-slacken it and pull the cable grabbing it from the base out also gently.

Do not pull it with force otherwise many problems can occur.

Also be extra careful to not pull it out from the socket of the cluster gauge!

On a 25 year old car it could be a good idea to change the gearbox oil to help a bit with shifting, replacing the gearbox oil with fresh new better quality gearbox oil after a thorough hot/warm drain of the old oil and whatever else out of the box.

Don't follow some of these idiot guides available on the internet, always check and remove the filler/level plug before removing the drain plug as you don't want to find you can't get the filler plug out after you have drained all the oil out of the gearbox.

Redline (MTL) if you can get USA stuff or any good quality synthetic 75W or 75w-80W or if it is hot in summer 75w-85 or 75w-90, all to GL-4.

1. There is metal plate with 9mm screw and is nut on the cable.Which one need to be removed first?

it is unusual way to check gearbox oil. if gearbox is not leaking visible, oil level is correct, if it is not changed for years, change oil, you need 1.5 litre ow 75w80 oil and 17 allen key. if you dont have it, use M10 bolt long about 5 cm and put 3-4 M10 nuts on it and tighten them. this should be good as tool.

The 9mm hexagon screw, then pull the metal plate (it's there for security reasons) and gently unscrew the cable.

Be extremely careful to don't pull it towards the bumper too much otherwise would be ''unclipped'' from the gauge cluster.

Here is the other end on the cluster.

Inside the hard plastic hose is the wire with a square tip,take the chance to lubricate it a bit (the wire not the tip).
