Not ****** ya Brutha. I totally get it.
I almost got that $1k tranny myself, but decided to have my old one rebuilt instead.... for the very reasons you laid out. Of course, I used my turbo money to do it with, got tranny, no turbo.
I totally know what you mean by spending more on the old girls than what they're worth. The only reason I do it is, I really like the truck and I see it as a long term keeper.
Bought the truck for $1,500, already spent over $3500 on it, just upgrading and replacing worn out rubber, IP system and other little stuff. Still, very happy to do it.
The things I see with these trucks and most common failures are- entire fuel system, brakes, and some minor electrical issues followed by trannies. That said, look how many miles these things are giving us, and what they're asked to do. Add to it the general age, and these are some wicked awesome trucks!
Besides, no way I'm paying $50-$60k for a truck I beat up! That I can't generally work on without a $2500 software program. Eff THAT!
