NV3550 Fluid Change Question
 
Ok, since the fill port is on the side of the tranny is there a way to get the fluid in there without buying a fluid pump?

kfdjason7620 04-30-2013 08:55 AM

How about an pump style hand soap dispenser with a piece of clear tubing on it??

TTTE 04-30-2013 09:24 AM

Nice! lol

kfdjason7620 04-30-2013 09:42 AM

I've seen it up here somewhere before.

TJspeed 04-30-2013 09:53 AM

Just put a tip on the bottle. That's what I did. Easy to do.

TTTE 04-30-2013 09:59 AM

Thanks TJ. thats probably what ill do. I know a couple type fluids have one on their bottle. Do they have those tips for sale at auto stores?

They might. I know Wal-Mart has them to.

A cheap fluid pump is 7 bucks and will make it quick and easy to refill. I highly recvomrbd going they route than trying to pour it in at an awkward angle

SpoiledRotten 04-30-2013 11:24 AM

I've never heard of the flushing with diesel. I suppose it can't hurt. I'll give it a try. My second gear will grind a little if I'm not easy with it. Thanks.

TTTE 05-01-2013 07:49 AM

So, i used Castrol 75w90 Synthetic yesterday. I dont really notice a difference in shifting. (still minor grinds going into gears 1-3...gotta give it a bit of a push to get it in lol) Also, there were metal shavings on the magnet...so, how bad is it? Mind you its a 2000 and im not sure if its ever been changed before yesterday.

JP4VPI 05-01-2013 10:42 AM

I would look into redline MTL for the nv3550 tranny. It's a bit expensive but helped mine noticeably over a 2 month span. I'm not up to snuff on the viscosities of engine oil n tranny oil but I don't think 75 90 it's the best fluid. Order the MTL online

TTTE 05-01-2013 11:45 AM

So its normal to see results over time?

75W-90 is what is recommended for the AX-15 and AX-5 which is what Redline's MT-90 is, the NV3550's requirement is closer to 75W-80 which is what Redline MTL is.

TTTE 05-01-2013 12:19 PM

Is there really a huge difference from the Redline 75-80 and the Synthetic Castol 75-90 i put in to where i need to change it now?

Jerry Bransford 05-01-2013 12:24 PM

Maybe not but the heavier 75W-90 viscosity might give a tad more gear clash in cold weather.

TTTE 05-01-2013 12:32 PM

or may i notice a difference in a week?

Jerry Bransford 05-01-2013 12:40 PM

Did you use Castrol Syngear 75W-90? I don't see where Castrol says that particular gear lube, which is a GL-5 that is normally bad for transmissions, is "safe for yellow metals" which means it won't harm the brass (yellow metal) gear synchronizers. SOME GL-5 gear lubes are indeed made to be safe for yellow metals but unless the gear lube specifically says it is, it's not. Most GL-5 gear lubes are not suitable for use in a transmission, they are actually meant for use inside an axle.

I looked at Castrol's webage at http://msdspds.castrol.com/bpglis/Fu...F90%5F3750.pdf and it gives no indication it is suitable for use in a transmission. Unless the back of the gear lube bottle you used says something like 'Safe for yellow metals', I would plan on changing it to something more suitable like Redline MTL.

No worries, it won't cause immediate damage if it's not safe for your gear synchronizers... it is only not good for them long-term.

TTTE 05-01-2013 12:50 PM

thank you. i used Castrol Syntrax Limited Slip. its GL-5. i think i need to change it again.

Jerry Bransford 05-01-2013 01:01 PM

Yep not the right stuff. http://msdspds.castrol.com/bpglis/Fu...lip%5F0656.pdf

I used the Royal Purple Syncromesh and noticed an immediate difference. I also did the diesel flush to clean any crud out. 2nd gear was a hard shift every time and now it's not an issue at all.

I think you meant Royal Purple Synchromax. :)

JP4VPI 05-01-2013 02:19 PM

I don't know if its normal to see changes over time but I certainly did. Granted it is warmer now than when I first changed the fluid but I don't have to wait 2 seconds when going from 1st to 2nd anymore after switching to the mtl fluid.

TTTE 05-01-2013 05:58 PM

Alright, i got that "night and day" feel. i just put in Royal Purple Max Gear 75w90. I just took it around the block and it dramatically helps! Thanks guys.

PedroJr 05-01-2013 08:36 PM

Hi guys ne one knows what type of fluid I need on my NSG370?

Mesh / Max almost the same :D

Glad she is on the mend. I'm now a fan of the purple juice

From JB in another thread

"Redline MTL, Royal Purple Synchromax, and Amsoil Synchromesh are all good choices for the NV3550 and NSG370".

Thanks man n do u know at what miles i need to do service on it? I currently have 68k n I'm gonna be doing my trough out bearing so I figure that since I'm gonna remove it I might it wells do service since I haven't do nothing to it.

mudmagnet63 05-01-2013 09:28 PM

Not sure on the fluid change interval, I waited too long on my 98 so a tranny swap is in the near future for me. While you are under there might as well change it, can't hurt.

PedroJr 05-01-2013 09:50 PM

yeah thats what I'm thinkin about doing, where u can buy the royal purple oils from? auto zone advance? its it better then the one from the dealership?

Does the transfer case use the same Royal Purple Synchromax too?
