Truck doesn’t change gears smoothly Have a 2006 CM870 I don’t know if this is an engine question or a transmission question but on my truck (06 Volvo) when I change gears sometimes it grabs when I go into the next gear. Even though I’m up shifting the truck kind of pulls back like I have downshifted. Even on my best shifts the truck still makes a little movement like it’s just not smooth. You can really feel it Low side and it’s not as bad but can still notice on the high. I have about 15k on a Cm870 long block, 56k on a eaton fuller 10 sp and just got a new turbo and air control box this week. I had these same issues with the previous motor and transmission as well. Any ideas would be appreciated. I’m running out. | |||

RE: Truck doesn’t change gears smoothly If you have leaky injectors or if the metering actuators are leaking and worn out, it can be harder then normal to shift, as the engine does not rev down as well as it should when letting off the fuel pedal. Run an overhead valve adjustment again and then do an injector leak test on it. http://rawze.com/forums/showthread.php?t...8#pid67948 A person can also monitor the live fuel flow into the engine to see if it goes to zero mg/stroke while idling.. or fluctuates around up and down like a sign wave. This is an indication that there are issues with a metering actuator. User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||

Thanks! I think I’m leaning toward the actuators. It has done the same thing with two different long blocks. How can I tell which actuator is the one giving me problems. Metering on the outside timing on the inside correct? | |||
