i agree with this.
i bought a 2002 caravan that had sat for over 5 years just for the transmission/transaxle.
before i bought it, my one buddy and i [he knew the person who owned it] took a fresh battery, gas, air tank, and tools along to see if we could get it running, and if the transaxle/transmission was working ok.
hooking the battery up, it cranked over just a few times, and fired up ! it sounded good, and the fuel gauge read 1/2 tank, so off we went.
the thing ran great on the super old gas, shifted as it should, so i bought it.
the transaxle lives on in my "bus", and other than a trans-go shift kit and fluid and filter change, works great.
throw some new gas in it, add a can of seafoam if you want, and don't look back.
