this is also a good site to ask questions about the m151
hope this helps|||If it%26#039;s a manual, bring it to a auto shop. They%26#039;ll know where to do that. If it%26#039;s an automatic, there will be a place to check the fluid underneath the hood. That%26#039;s where you will add the fluid.|||You add fluid through the pipe the transmission dip-stick goes into.
