The Adventure Bus Breaks Again... (Patreon)

Unfortunately another major problem has arisen in the Adventure Bus: the transmission... The other day I was driving it home from a camping trip and realized the trans temp was reading "-69°" and the overdrive light was flashing. I didnt think much of it because it was driving fine, no weird sounds or leaks, just figured it was a bad temp sensor. I didnt have time to get it fixed before going on another, farther camping trip last weekend. Once I got back from that trip I realized the trans was seriously leaking fluid. There was a nice puddle and trail leading into the parking spot where the bus was parked at the shop. I had a diesel mechanic come by and check it out and after a little bit if searching he found that the front pump seal had blown. That requires the transmission to be removed to be fixed. The main problem is we have no idea how long it had been leaking and how long I had driven on it with low fluid. It's possible the trans is completely destroyed, although I'm hopeful since it was driving perfectly fine when I parked it. Either way it's a huge bummer and another expensive repair. I'm starting to think this bus might be more effort and expensive than its worth. What do ya'll think? Fix it and sell it? Or fix it and keep it and hope nothing else breaks? I remember saying those exact words when the engine blew haha.
