" No More Codes"

[lucerne tractor]

This is the first time since I have owned the truck where I can drive it for a few miles and no code pops up. I was in San Antonio and went to the border at Eagle Pass to get a tall load. The ecm/vgt code went off a dozen times, usually it goes off and all is well, lately, at times I have to pull over, shut it down and restart and it's fine. This time I had to pull over 8 or 10 times and sometimes it didn't work the first time. I got the load and thought this is going to be hell getting back to San antonio for repairs, "IF" I make it. Made it all the way to Greensboro NC to my favorite Mack dealer, real pro's no parts changers. 100 miles before I got there, getting off a ramp if I held the brake the air would drop to near buzzer area, so made a new problem on the way.

Made it to NC, here is what they found,"AIR LEAK" I had picked up a rag or something on the driveshaft and it had slapped two air lines so long it wore a hole in one and near through on the other, he showed me the shiny spot on the U joint where the rag was, I remember it was a torn up soffa cushion, I missed the soffa and the first cushion but got the second. Great detective work.

"VGT CODE" someone in the past had taken off the small oil air seperator filter that is in place at the rear of the drivers side engine, more great detective work,it filters the oil out of the air before it goes to the vgt sensor controll that is mounted on the firewall under the stearing colume. The sensor was going wild because of oil. They installed a new filter system and a new vgt controller.

"LACK OF POWER" You are allowed a five pound loss of pessure in the charge air cooler in 15 seconds pumped to 32lbs, I lost 32 lbs in 5 seconds, the charge air cooler was cracked down the side, they replaced that, called Mack for all the updated down loads including 12b. No codes, she pulls for the first time and runs soooo smooth!! Milage is way up and still climbing. They did the heads for me when I lost them because my local Mack Garage set the valves too tight. Highly recomended, Transource, 8700 Triad Drive Greensboro, NC Jeff for a mechanic and the fella that has been there for 35 years for computer power related stuff. If you need service in the area, they hav a tv room, laundry,showers, and will shuttle you anywhere for free, even out for barbecue. They aren't fast, but are precise, not cheap but you only pay once.

Have been using Transource for all my service work since moving to VA. Greensboro is only about 50 miles from here,i personally have nothing but good things to say in my dealing with them. My only complaint is as you mentioned,they are S-L-O-W! but i have never brought the truck back to them for the same repair,plus i think it does'nt hurt that Mack is now headquartered literally right across the street!.....................................Mark
