hello…. so my omega caravan has original 122 tkm on the clock and since about 2500km the gearbox is getting worse… that makes itself noticeable on the first and very bad in the 2 course….. so if I want to run empty in the first and then want to switch up in the second 1 question… what is that… 2 question… what can or must I change it… 3 question… what does the whole fun cost me… 4 and last question for the first… can I continue driving so you get used to all MFG
