Alright due to the weather in these parts I have a pretty good coat of mud built up all over the taco. I'm fixin' to make a 400 mile roadtrip today, and my brother told me due to the mud caked on the transmission housing I am running the chance of overheating the transmission (06 5spd). Any truth to this? I would go wash it but it's going to be just as bad next week. What say you TTORA?
