why not recommend it? what do you think would happen?IdahoDoug said:I've driven a couple vehicles, including both 80s, with an extra quart in them for periods of up to a year including some heavy towing. I don't recommend it, but if you find it like this no cause for panic. It's actually pretty simple to put a drain pan under the 80 and pull the tranny drain for 5 seconds or so before slapping it back in. You'll have a messy hand, but that's about the extent of it.
