On the 4.0L AX-15, it's on the passenger-side, near the front bottom edge. On the 2.5L AX-5, it's on the bottom. Which do you have and what location are you calling the fill plug?

Yes the bottom front on the passenger side is the drain plug. On your AX-15, the fill plug is half way up on the driver's side.

Yes, level with bottom of the fill hole is right. Just be careful what you fill it with as many of the GL-5 75W-90 gear lubes are inappropriate for the AX-5 and AX-15. If it's a GL-5 and doesn't say that is is compatible with yellow metals like Royal Purple Synchromax, Redline MTL, and Amsoil's 75W-90, then I'd be wary of using it. The AX-5 and AX-15 trannies are a bit fussy about their gear lubes.

I would like to ask a question (I do not want to open a new topic, since it already exists one): I have a 2000 4.0L TJ with the 5 speed manual tranny - I presume is the AX15, right?
What kind of oil, other than Mopar, shuld I use? In the manual it says "use only Mopar Gear Lubricant... This is the only fluid recommend for this transmission". Now, I doubt that this would be the only tha's suitable. On the other hand, you were talking about RedLine and other brads that I cannot find in my country.
What is relatively common here (and affordable) is the 75W90 transmission oil from Castrol: TDS-TAF-X-1862 , Mobil: Mobil Delvac Synthetic Gear Oil 75W-90, 80W-140 and there are others, but not so popular (Aral, Metabond etc).
Should I use something else, maybe (other viscosity)?
Or should I stick to the Mopar and that's it?

if you have a 2000 then you have the NV3550 you can use mopar transmission fluid or Pennzoil Synchromesh.

I got this from the Pennzoil Website:
Quote:
APPLICATION
PENNZOIL® SYNCHROMESH FLUID is specifically formulated for synchromesh transmissions used by General Motors
requiring General Motors Part No. 12345349 (Specification No. 9985648) Synchromesh Transmission Fluid or Chrysler
transmissions requiring Part No. 4874464 (Specification MS-9224). It is also recommended for use in General Motor
transmissions requiring General Motors Part No. 12345577. It is listed in the Pennzoil Lubrication Recommendation And
Capacities Guide as “GLS.” PENNZOIL® SYNCHROMESH FLUID is NOT intended for all GLS applications. You
must verify the manufacturer’s part number, indicated by a superscript number and found at the end of the vehicle
application listing.
BENEFITS
• Exhibits excellent low temperature performance
• Meets GM Specification 9985648
• Suitable for use in GM manual transaxles and transmissions requiring GM Part No. 12345349 or 12345577
• Meets Chrysler specification MS-9224
• Suitable for use in Chrylser transaxles and transmissions requiring Part No. 4874464
• Excellent synchronizer performance
• Excellent yellow metal compatibility
i know a lot of guys use the pennzoil in place of the mopar oil. pennzoil is 1/2 the price of mopar and it meets the same specifications.

I changed my tranny oil out a week ago. Just a tip to you, i would go to the auto parts store and purchase a little $5 hand pump that screw onto the top of the tranny fluid bottles. Trust me if you do that i will have saved you about an hour and a head ache.

the manual says that the ax-15 holds 3.5 qrts. i put in about 3.75 qrts and it still didn't flow out of the fill plug hole. im assuming that im fine. Shifts great!

Thanks. I was just writing to say that it seems, indeed, that is a nv3550 gear box, when the replies came.
So, no other fluid than Mopar or Pennzoil.
This means that the gear oil change will wait a little (we don't have Penzoil in Romania and the Mopar is extremely expensive).
How many liters will go in?

I just changed mine this week, and used the Penzoil. It comes in Quart bottles and I used 2 and about a half of the third bottle.(i spilled a little too).

Just did my NV3550. and with it, you don't need the hand pump. just cover the hole on the bottle with a finger, and get the bottle up on the far side of the drive shaft, then you can turn the bottle and get it right into the fill hole. entire process took less than 20 mins.

Just make sure you have a huge allen headed socket (17mm allen key)

takes just over 2 qts...for the life of me I can't understand why it always takes just a little over x number of qts. they could make it easier on all of us, and just require 2.0, or 3.0 qts.

Popa, if you have GM dealerships there you can get GM syncromesh as its the same thing as the Pennzoil...just with GM written on it.

Nop. I am still looking for the Mopar one (it seems that the manual tranny on TJ's is not common in Romania and the dealers do not have the Mopar in stock).

30 weight engine oil is pretty darned close to 75 or 80 weight viscosity gear lube.
