Ask a Peterbilt Dealer!

In all of the trucks I have driven the Cummins so far has been the most reliable, but the newest that I have driven was in a 2007 Pete 387. Do you have any suggestions for a better engine?

 

Here's a question for you.
Does the latest model Pete (with MX engine) use CAN communacation lines,just like it's European cousin?
If so,are they the same as it's EU cousins?

The MX engine running in the USA,is it a common rail?

 

Peterbilt used to make an all canvas hat black with under side of bill green with a true peterbilt oval patch on it not embroidered ........ had worn a hundred of them...... bring them back or sell me a hidden box of them
THANKS!!!!!

 

my dad recently bought a 08 388 with a c15 and a 13spd, the tranny will auto shift from 12 to 13 and back to 12 based on rpms is there a way to disable this through the ecm? if u need the make and model of the tranny i can get them i just dont have them at the moment/ thanks for any input

 

I want to put LED bulbs in the front on my 388 for turn/clearance instead of the regular amber bulbs. Will you need to put in resistors, relays or anything?

 

Why won't my low beams work on my 387 Pete any suggestions

 

Just bought a '14 386 with 550 cummins. On the top digital readout, I am getting an x displayed right above where the cruise speed readout is located. Its not always there, just sometimes. I am also noticing that in the top 2 gears(13 speed), I am only able to get about 32 lbs of manifold pressure and the power just dies out at that point and the truck seems to sputter a little bit. I have 8000 miles on it, am wondering if it just needs to get brokein yet. I am sure hoping so, because its really sick on power and fuel mileage. Thanks for any help.
