I have a Claas 836 rz and often started having the blocked transmission light come on, I’ve taken all filters off and checked them (although they are due a change this week) but all seem to be pretty clean. The light goes out once the tractor is warmed up and being used, also noticed a bit of condensation on the on the inside of the oil filler cap so not sure if that’s a big issue? Anyway is there a common problem or should new filters solve the issue once I get them?
