|08JJ||I personally like the redline mtl and since summit is 1/2 hour away it gets me out of the house. For me it made 1st and 2nd gear sync better but that is me. I hear some folks like the pennzoil syncromesh and the royal purple better but I am sticking with the Redline MTL in my TJ's NV3550. The Redline is pretty thin, it's almost like ATF.|

|PedroJr||Ok thanks Jerry but I would go n check autozone or Carquest to see if they have it. If they don't i gona have to go with the one from O'reillys|

|Patrick H||I didn't realize there was two different RP manual transmission fluids. I assumed Synchromax was the RP fluid of choice. I wonder if it's super thin like Redline MTL?|

|Jerry Bransford||If they don't stock Royal Purple Synchromax, the Max-Gear 75W-90 is a suitable substitute. I checked out RP's Max-Gear 75W-90 a few days ago & verified it is safe for the transmission's synchros. Its viscosity is close enough to be fine.|

|JP4VPI||If its never been changed its good to do. Both the fill and drain plug should be 10mm Allen head bolts. Should need 2 quarts. Also just make a crappy funnel to drain it away from the skid plate. Otherwise tiny drips of old t case fluid will trick you into thinking everything is leaking. Ask me how I know.|

|Jerry Bransford||Yep the tcase likes any good quality ATF, ATF+4 is a good choice.|

I have read so much I think I have information overload on Jeep lubricants.

|mudmagnet63||I got my RP from O'Rileys I'm not sure on the transfer case I would be interested to know it's next on my list. I think the Tcase is just ATF|
|05-01-2013 10:26 PM|
|JP4VPI||Transfercase gets ATF +4|

|PedroJr||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?|
|05-01-2013 08:28 PM|
|mudmagnet63||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.|

From JB in another thread
"Redline MTL, Royal Purple Synchromax, and Amsoil Synchromesh are all good choices for the NV3550 and NSG370".

Glad she is on the mend. I'm now a fan of the purple juice
|05-01-2013 07:36 PM|
|PedroJr||Hi guys ne one knows what type of fluid I need on my NSG370?|
|05-01-2013 04:58 PM|
|TTTE||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.|
|05-01-2013 01:19 PM|
|JP4VPI||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.|

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.
|05-01-2013 12:01 PM|
|Jerry Bransford||Yep not the right stuff. http://msdspds.castrol.com/bpglis/Fu...lip%5F0656.pdf|

|TTTE||thank you. i used Castrol Syntrax Limited Slip. its GL-5. i think i need to change it again.|
|05-01-2013 11:40 AM|
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.
