just a cummins they have there issues!

Give us a Side view! How thick?

Bro I think turbo washer now I know the size seen this before turbo gave out at som point . you have only had this truck for a year do you have history on the unit bet it had a turbo failure!

Eup cap? Doing retainer maybe don’t no how it could get out of the lifter thou?

Hard to tell the size of it. could be a turbo washer from a previous failure hopefully a valve spring it can be replaced in frame!

In the vmac III program you should be able to see the temps the ambient air is seeing the inlet air temp should be visible as well ! Is it possible they bent a pin on the ECU while installing the new Harness?

correct it may have stuck after sitting wouldn't fuss if it has no code now! How old is the oil! Maybe change the oil !When its working correctly , It gets its orders from the the ecu the timing event marker and the cam sensor according to temp ect!

Is the code still active? The if the timing advance is working you should not have smoke if it’s not working and smoking blu white smoke the screens in the timing Solenoid could be plugged up with goo!

Disconnect the big plug at the engine ECU and wash the oil out with brake clean see how that goes for ya! just something to try! This was a common issue at one point!

Good Job Bro!

Is It coding when it derates? if its producing any more than 33 psi boost it may d rate!

as much as the above statment is some what true have you checked for boost leaks? your pyro is to way high!

The offset and Taper helps align the teeth with friction when the shift is make your fuller trans has the same set up however much simpler in design and Less complicated! And way Cheaper to Repair IF it fails!! Make sure all the pieces marked R are faceing Rear and your good to go! That set up sed to be offered as a pre assembled unit just drop the discs and seperators in and go! if I remember right!

You don't often see the plate carrier busted up that bad ! usually the clutch and reaction discs are toasted ! was the yoke bolt tight? Yup this is why Daves comment is somewhat valid! The price gouge on those is your next hurdle! Volvo wants you to buy a new truck So Those parts will not be cheap! That same failure on a fuller When it does happen which is not that often ! will cost a 1/3 or less than the Mack parts! They are going to ask you if you would like it dri or lubricated BEND OVER BUD! . Check out PAI for part pricing! That being said These tranys have put food on my table for a lot of years ! Just like injector cups will make work for the new generation of guys for a few more years!!

WE HAVE A TAKE OUT 460 ! CALL RYAN @ NANANAIMO MACK COM ! 2507580185

yup

Top REAR engine mount rubbers removed the trans should clear the x member shift cyl on!

Just my opinion the CL is the easiest truck to work on if the truck has no pto ! take the trans out stand it on end and Take it apart that way! also if this trans has Cummins in front of it the job gets more complicated the tail shaft bearings have to be set in the press! And there may be an extra spacer you'll need to buy from mack to set the preload! You could wait for days for the plate to do a job in the truck once on the ground you don’t need the plate. The spacer you may need was updated from a crush sleeve to a solid unit of varying to be determined thicknesses! Also if your determined to do this yourself ,Price your parts thru PAI quite a bit cheaper than Mack stuff and as good quality! As for the shift cyl I would leave it alone the seals in that a quite durable unlike the range clutch! 😒nuf said!😁 again an opinion!

Is there a check engine light on the dash? Could be the econovance has failed the little ( box in front of the fuel pump) you can tri put 12V to it see if the issue clears it up! the solenoid could be weak on this !causing this issue!

Just A note to Tech's literature here !His last pic shows the actuator pin side view ! The little mushroom end had a a tendency to break from time to time you should always check these when setting the valves and jakes replace the screw if broken and good luck finding the broken bits! 😒

No but it sounds like the turbo maybe sticking! Replacing the actuator will not help if the cone / vanes are sticking inside the turbo usually the turbo needs replacing !

Have you changed any parts do you have tech tool check the fuel pressure! 7th injector Can causes issues!

So I'm going to throu this out there, If you have a mack trans and you a missing approx half your boost check the torque limit switch at the rear of the trans! if it malfunctions the Vecu will derate with no code as it does not see any malfunction !IT Thinks everything's is AOK!
