now this might be kind of a waste and a rookie question but is there a reson or a way to monitor the temp on a NV 5600??? has anyone ever done this. i was just curious. i know it would take alot to make that trans work hard but i was curious.

Pull the drain plug , measure how far into the trans you can get [ shift in all gears to check for clearance ] get a gauge & temp sensor with those measurements in mind .
You could also just epoxy a sensor on the outside of case , but a little lower reading .
Use a inferead temp gun after test drives go find gauge range .

there is a drain plug on the nv 5600?

No drain plug as I recall. Drain through lower bolt. Remove a cover. Drill and tap into lower part of one cover, tap to correct size. Install sensor, and wiring. You're done.

heat is not their problem

Yes it is, that's why they suggest to overfill, to increase cooling by circulating more oil.
They can reach temps of 270deg and above, at that point your oil life is reduced by 1/2 and it's almost completely useless.

I installed the coolers that fit on each PTO cover, one of the coolers has a plug for a temp sending unit and a drain plug also. They will add 2 quarts of oil.

My next step this summer is to add a temp gauge for it.

do those finned PTO covers help out much. i mean i dont do a ton of pulling with my truck but when i pull i pull a good size load. and i was just wondering about monitioring my manual trans because the auto guys watch theirs. so for a temp gauge set up i would need

gauge
wiring
sensor (where do i get this)
and....???

Right - heat is a huge problem for the NV5600, because they require a light fluid (like Redline MTL) because of the non-metallic facings on the syncros - which have a tendency to destroy themselves.

So - use synthetic fluid, change it often, and - if you tow and want a margin - use the following:

1) finned coolers - use one on a PTO plate of the NV5600
2) an Eaton manual transmission filter - use it on the other PTO plate
3) you may have an extra finned cooler from a set - use it on the transfer case PTO plate if you've got a 4x4

The filter will help with the large amount of "sludge" the NV5600 produces. Together, the filter and the finned cooler will give you an extra quart or so of capacity, further helping with cooling. And it never hurts to add capacity to a transfer case, either.

Nearly all the coolers I've seen have drilled, capped holes for sensors. The Eaton filter assembly does not.

I have a Juice w/attitude, and it came with a trany temp sender. I have a manual trany and installed it per instructons in teh juice setup, into the PTO cover on the lower corner. Works fine.

where can i get that filter and the pto covers?

thanks alot guys
which combo of those parts do u sugest. i would mlike to run the filter but i want to cooling help too.

Heat is a huge problem with the 5600.

Weld a bung onto the drivers side PTO cover and install your temp gauge. You will see temps that you didn't think you would, especially towing in 6th gear.

Over fill your trans with 6 qts thru the shift tower, change the oil on a regular basis and keep an eye on the temps and it should live.

Anything to keep the heat at a minimum will make a difference, Fast coolers, finned PTO covers, over filling, it all helps.

The 5600 is a good trans, it just needs a little caring for to help it survive.

I've had temps running empty on a flat highway, in 100 degree heat, over 230 degrees and I'm not even towing! I've had temps way higher when towing but found that just a simple down shift for even a few miles will drop the temps considerably.

Oh, sorry, an other NV problem......

I wish some people had some good suggestion or information instead of just wasting bandwidth.....

Whoops, what am I doing ?
