14k on MTL NV5600 /Filtered

[jwilliams3]

Well today, I decided I would change the Redline MTL transmission fluid out of my NV5600 6 Speed.

I went out and purchased a 17mm hex head socket at Auto Zone (pack of 3 for 7. 99).



I had to use a standard type oil bottle and a hose attachment to get the oil into the fill hole.



Next I drained the oil from the bottom hole of the PTO cover on the drivers side.

To my immediate surprise the oil was a clear and very clean yellowish/reddish color.

The oil was not dirty at all!! I was really surprised being that I am running a dual disk clutch that is really hard on the synchro's. I figured there would be a mixed of flakes in the oil.



Well, I am also running an EATON filter kit on the PTO cover and this probably contributes to my oil results. Anyhow, the oil was really clean and I was impressed!!



The oil did not need changed. Next time, the current batch of MTL that replaced the previous I will run it 25k miles and see how it goes.

Finally changed the factory transmission fluid in my 5600 at about 180k and was still extremely clean. Other than a stench, I would have run it another 75k and not been worried about it. I replaced it with Penzoil Synchromesh and 20k miles later no problems.
