LRMark26 Transmission fluid changed. Put in 2 full quarts before it started coming out of the fill hole. The garage slopes slightly to the front of Jeep and when I opened fill hole the old fluid started pouring out. Should I just turn around a put in a little bit more fluid (calls for 2.5 quarts) or just sometime in the next week take it to a Tuffy and have them lift it level to check and add if needed? I know too little fluid is bad but is too much bad as well?

The old fluid was throfty and the drain plug had some good buildup but no big pieces of metal. Not sure of last change, "should" have been about 25,000 miles ago when I bought it.

Used the Royal Purple Synchomax $19.99 at Pepboys and last time I get it there. They only stock 1 to 2 bottles at a time and truck only comes once a week... Will use Amazon next time, couple bucks cheaper free shipping and will have it in 2 days.

jeepsrgreat Thanks for your help Jerry.
I think I'll change the transmission fluid again. It's easy enough.

Only if you filled your transmission with that Lucas GL-5 75W-90. The information you want to see associated with any GL-5 gear lube used in any of our transmission are words to the effect "safe for yellow metals". Most GL-5 gear lubes have harsh sulphur-based additives in them that give them their GL5 protective traits which are required in our axles.

Those same sulphur-based additives are harsh on the "yellow" metal brass synchronizers used in our transmissions. The only suitable GL-5 lubes that are safe for use in our transmissions will have those 'safe for yellow metals' somewhere in their description. Lucas does not say that for their GL-5 75W-90 anywhere on their website at Lucas SAE 75W-90 Synthetic Gear Oil : Lucas Oil

Like the GL-5 75W-90 on Royal Purple's website at Max Gear - High Performance Gear Oil - Royal Purple where it says "It is non-corrosive to soft yellow metals (brass, bronze, copper, etc.) and synchronizer safe"

Redline has a similar safe for yellow metals 75W-90.

My feeling on Lucas' 75W-90 is that if it doesn't say it is safe for yellow metals, and it doesn't where I can find it, I wouldn't use it in a transmission.

Don't panic if you have already installed the Lucas 75W-90 into your transmission. Its harsh effects are strictly long-term, it won't do anything bad in the short term.

jeepsrgreat I just changed my diffs and transmission before reading this post. I used Lucas 75-90. Did I waste my time and money? Should I change it again? Cold climate here....down to 40 below. Just bought synthetic 5-30 for an engine oil change but haven't done it yet

Trans fluid

I just bought four quarts of royal purple gear oil for my 2000 sport with a 4.0 in it and it was 20.99 a quart .It takes 3.4 quarts so I will have some to top it off if necessary.I found it a Advance Auto Parts where I buy the Royal Purple engine oil for my wifes Mercedes.I called around and could not find the stuff any cheaper than 20.99 a quart, the engine oil was 9.99 though.This was about the same as the Mopar brand and its way out of warranty so I went with the Royal Purple.

LRMark26 Great information! All the talk has been about Synthetic in extremely cold climates. Logic tells me in non-cold areas don't use the Syn. But would like some advice for my current issue.

I live in northeast FL where we get into the 40's on average in the winter nights. 2nd gears typically grinds first thing until it warms up. But the last month or two my 5spd manual tranny (2000 4.0L) has been kicking out of 1st from a stop, grinds 1st to 2nd and 3rd to 2nd. Started to develop after heavy rains and big puddles, damn tropical storms and hurricanes.

I have read that those with similar issues changed fluid to RoyalPurple and solved the grinding issues. Would you recommend using the RoyalPurple through the winter here then switch to the non-syn before summer; put in RP and forget about it till next fluid change; or just use the non-syn recommendations?
05-26-2012 02:57 PM
Jerry Bransford One more good lubricant for 2000 and newer manual transmissions is Redline MTL, another full synthetic.

SIXTI Great info. Thanks

Just because it can get cold there I would run a synthetic like Royal Purple Synchromax or whatever Amsoil's equivilent is. Pennzoil's Synchromesh is not a synthetic, it is a mineral-based gear lube. The right synthetic gear lube can help a transmission shift a little better in extremely cold weather.

Thread Lock

Gentlemen,

Well, I have my annual Jeep event this weekend, so last weekend was spent installing Racks and Covers, Removing Doors, changing Oil, and doing a few inspections when low and freaking behold, I found that it appears that I have both oil and transmission fluids leaking from their respective drain plugs. It isn't much, but enough to annoy the heck out of me.. FLUID LEAKS DRIVE ME TO DRINK!

So, considering that my Jeep will be running for 8-10 hours for 2 days straight, I would like to possibly find a solution.

Do any of you apply Thread-lock or some type of sealant to the Oil and Transmission Drain plugs. I inspected around the tranny and oil pan and didn't notice oil leaking from anywhere else. Just near the plugs they are both wet with fluid.

Thanks in advance for the help!

If you wish for a full synthetic. Yes.

Welcome to the forum.

What trans do you have??? auto or manual?

If you have never had it changed....YES!!!! change it, you don't know how the last person drove it or if it has ever been changed.

Good advice for every used auto is to have ALL fluids changed after purchase so YOU know it's good.

Thanks Jerry!

Yeah, i find myself with a ton more tools that I had before I bought this Jeep.... IN AUGUST!!!

I am also due for a Roller chest.. I am sick and tired of digging through that bucket that is my rubbermaid tool box for a 19mm socket!

Next stop; Differential fluid change!

Done!

Well Guys, I drove over the hills and far away, but was able to locate the Royal Purple Transmission Fluid and the change went off without a hitch.. It was a little messier than I had anticipated, but it was my first transmission fluid change, so the next one should be a little easier..

Really, the hardest part was trying to find a zip tie which would hold the plastic pump on to the RP bottle after I promptly broke it... I mean real prompt... As in, before I even pumped an ounce of fluid into her. The metal shavings connected to the drain plug we a little tougher to clean that what I initially thought, but oh well.

I followed the exact instructions as indicated on 4x4xplor.com (w/ the exception of the mopar fluid) and after my test drive I found that she shifts a little nicer... Pretty proud of myself over here for being a ROOK!! Heck, that was my first time using a Torque wrench.. Oh! I am now the proud owner of my very first "Creeper."

Thanks for all the help guys I really appreciate it!

That is a great idea Stevens..

I wasn't able to locate where 4wheel parts offers an ARB D30 diff cover.. I will contact the store and see if they do have one available..

Noted.. I will most definitely keep that in mind..
