Used 1984 Ford e150 120k great condition but needs trans work - cars & for sale in San Diego, CA

1984 Ford e150 van that has been well maintained it’s whole life. 2nd owner, both non-smoker mechanics, and serviced regularly. Transmission recently stopped shifting into 2nd, but was smooth until then, maybe an easy fix.
302 5.0L engine and AOD transmission. 120k original miles with hitch and tow hookups. Perfect space for traveling/living/working in your van.
Interior is in amazing shape too and I’ll send more pics if interested. All maintenance was entirely preventative, never broke down until now.
