Then you probably won't have problems shifting from low to high ratio

CDL engaged or not will not present problems with range shifting, 2 seperate machanisms

Hi DeeJay - its been a slow day for me so maybe I am a bit slow, so sorry I don't follow your point.

Basically I select the cdl when I think I need it, I select an appropriate range and sometimes the two coincide, sometimes not. In slow technical stuff certainly low range/cdl (though I did do Monkey Gum without knowing my cdl was not working) but higher speed hi range offroad the cdl is usually out as it chatters away above 70kph.

No probs,
For you- I will explain. This thread is about a forum member who is experiencing difficulty changing from low ratio to high. One explanation not forwarded was the possibility of transmission wind up causing it to be difficult to shift. The fact it was made easier by reversing made me think it was a possibility.
Why would this not be a reason?

I mostly use the button in high range. With a turbo I rarely need low range. :-)

I have experienced the high/low leaver on the LT85 freezing because of corrosion. WD40 fixed it. It may be worth a try.

OK - I had a look back through the posts and missed your initial post about transmission windup as the cdl was on. My post asking whether we were talking about CDLs or Hi/Lo range was not aimed at you but AIF said - as I indicated I missed your post until now.

I see where you are coming from. I am not so sure but only because I have never experienced having trouble changing between hi and lo because of windup but can see it may happen - I have had plenty of experience with the opposite in not being able to disengage the CDL because of the CDL.

Thanks for that clarification - I was concerned that I may have missed something which I had.

Most likely it is because of the input gear modification done to the majority of the perenties as they needed gearbox repairs. As i stated earlier, harder to engage but less prone to disengaging. This modification required replacing the engaging flanges of the input gear with full length teeth ones.

Thanks for these answers.
Normally I change when stationary which could explain the smaller linkage gap and/or transmission windup because, as DeeJay noted, my TC issues are Low to High. I'll try reversing and see if that helps.

Which leads me to another question - Why do TC gears need to be so much stiffer and more difficult to operate than regular GB gears? Why didn't they just invent something like a mini TC clutch?
