Pumped the whole section full of grease ,
Probably not a good idea to put too much grease in there. Remember that it is your main heater duct, so I hate to imagine the mess when you get some cold weather and that grease breaks down to solids and oil ?
But seriously, if that white bushing on the geralever breaks up, you will not be able to select gears. I hav ejust been thru that and had to turn up a bushing out of 1" round nylon bar.
