Gear change

I'll ask the friendly one at the corner again, which contains everything you asked about the oil change.I think the price is justified when disassembly of the oil pan,incl. sieve changes or cleaning.is just quite expensive.I have no possibility to control the oil stand in the gearbox, it lacks the wedge rod.I think that self-making is not so easy (because I let off and tip again about:....liter too) will go wrong already.Many thanks for the numerous answers.is really n super forum.
