History
Currently sits at about 160k miles. Has had some transmission work - (found out Diablo sold/shipped me wrong programmer that I ordered that caused the tranny issues. Corrected issue.) - She needs a little TLC but I plan on putting some work in to her more now that she's not my primary driver.

Shortly after the person hit my front bumber, the truck started having sporadic issues until it died on the off-ramp of the highway. 2 Years later after looking different systems over, I found out I had a loose ground behind the front driver's side bumper. - Cleaned up and reconnected it and it ran perfectly.

Replaced rusting out break lines in 2017.
