I was driving back from a cleaning job in the next town over when my work van started making this grinding noise every time I hit 45 mph. Pulled over at a gas station and checked the fluid, it was brown and smelled burnt. Called three different shops and the cheapest quote I got was $2,800 for a rebuild. I don't have that kind of cash just sitting around so I ended up buying a used transmission from a guy on Facebook marketplace for $400 and swapped it out in my buddy's driveway over three afternoons. Took me 14 hours total and I skinned my knuckles about six times but it fired right up when I was done. Still driving it a week later and it shifts smooth again. Has anyone else taken on a transmission swap themselves and regretted it or was it worth the hassle for you too?
