If you need Auto and Diesel mechanical work performed in the Red Lodge, Montana, area, I highly recommend Chris Pedersen - Pedersen Diesel Specialist.  Chris helped us on our camping trip to Red Lodge, Montana, last week.  We had serious problems with our 2016 Ford F-250, and it would not pull our camper trailer up the ridge heading into Red Lodge from the east.  Chris "happened to be" going our way on the highway and encountered us unable to make it up the hill. [I don't believe in coincidence!!] He assisted us with a short pull off the highway, checked out our issues with the diagnostic tool computer he had with him, and then helped us limp the vehicle up over the next uphill mile to the top of the ridge and down into Red Lodge.  He declined any payment for this action.  I insisted that he was going to do the work to resolve my issues, which he was able to work into his schedule on the second day following, and he replaced all 8 coil packs, all 16 spark plugs, and all plug wires, on-location. Test-driving revealed that both my catalytic converters were seriously plugged up, restricting the flow.  Chris was unable to perform that work in Red Lodge, due to parts unavailability, but referred me to a shop in Billings, MT, that could get the converters in Billings and install the next day.  Vacation Saved!!!  CALL CHRIS AT PEDERSEN DIESEL SPECIALIST!!!!

Took my 1992 Dodge D250 for transmission issue. I was given prompt service, kept informed and given a fair price. I’m extremely happy with the service and recommend for any auto maintenance
