Dazed and confused

[Northerner]

My problem is simple enough: My truck shudders starting out in 1;st or 2'nd gear after a drive of 20 to30 kms. It does not do this when cold. My dealer has been great ; they changed the clutch, the universal joints, and hanger bearings twice now. They also re-alligned the rear shaft and hanger bearing adding shims etc. But she still has the shudder on take off. Now I have had the transmission refuse to shift to reverse. I had stopped at a coffee shop after driving for 3 hours or more at highway speeds. I had put the clutch in as far as it would go and tried 3 or four times and all it did was grind. I let out the clutch in neutral then tried again and it went into gear. What could cause this in the transmission and is there something that could produce these problems together. 43,000 kms only. getting worried!

Sounds to me like a bad slave cylinder. You purchase a master/slave as an assembly, and installation is a piece of cake I think (compared with my old Ranger, which had a concentric slave cylinder so your only option was to pull the transmission ). Anyway, the clutch hydraulic assembly is where I'd look to next...

Thanks rbattelle; I didn't think about that . I can feel this in forward and reverse gears. does that fit with a defective slave cylinder? I gave some thought to how I can describe the feel and would say if you ever had a wheel bearing pack up completely it has that feel, but you can tell this is somewhere in the drivetrain. It is more severe when I put more load on by turning the steering wheel to make starting off more work or by adding more fuel from a start.

Well, the reason I went toward slave cylinder is your description of how it refused to go into reverse. My old Ranger had a slave cylinder that would leak air into the system. Over time, the clutch engagement would get closer and closer to the floorboards until eventually fully depressing the clutch pedal didn't disengage the clutch, making it extremely difficult to get the vehicle into gear.



Given that you've replaced everything under the sun in your driveline, I was thinking maybe clutch hydraulic system might be where to look next. Will this fix the shudder? I don't think a bad slave cylinder alone can make a shudder, but if it's been bad for awhile and the clutch has been dragging it could have overheated causing it to warp, which would cause a shudder (although you replaced the clutch, so who knows).

Any chance of bad syncros in the transmission. Obviously check clutch actuation first but... ...

I spoke to my dealer service rep and the next step will be a "transmission assembly". I sure can't complain about the effort on their part. I see some other threads on vibration at startoff in 1st or 2nd but no definitive solutions yet ?

Black flys

Hey Northerner,just blame it on the Black Flys,the transmission should start shifting fine come October!!!!Just pulling your leg-There are no synco's for reverse,If it was the actuator for the clutch you wouldn't be able to pick up 1st gear either,this is the first I have heard with the NV5600 not shifting,Is the shifter forks stock?Let us know what happens with the new transmission!

 

[Northerner]

The forks are stock. I bet DC would find the problem Quick!! for me if I they had to work outside with the black flies till they solved the problem. :-laf
