Transmission leak

Yesterday afternoon as i was mixing some cement for the house renovations my family. I have been working on it all this past weekend. My father came up to me and told me I'm leaking oil from the jeep. I thought it was no biggie till I actually noticed it. The leak is coming from my transmission/t-case area. The skid plate is covered in oil. i took some pictures tomorrow after i get home from school i'll drop the skid and see what i can clean up and hopefully find out why it is leaking. since i got the tj in 2002 with 42,xxx miles I've had trouble going to reverse. I would have to shift in to 3rd & 4th before going in to Reverse. Sometimes it would just go right in to gear without effort. Can anyone give me a prognosis of my leak?

here are the pictures









there's a puddle of oil just inside of the skid plate

First, that your transmission grinds when being shifted into Reverse without first shifting into 3rd or 4th is 100% normal because Reverse gear is not synchronized in the AX-5 or AX-15 transmission. Reverse wouldn't grind if you first shifted into 1st or 2nd gears either... shifting into any forward gear first synchronizes Reverse so it won't grind.

I suspect a seal on the transmission needs to be replaced but you'll have to first figure out if it's leaking ATF (bright red) which indicates a transfer case leak or gear lube from the transmission which is darker.

It may take you cleaning the transmission and transfer case multiple times so you can finally determine the actual source of the leakage. First, figure out if it's leaking ATF or gear lube though.

My 98 did the same thing
Some days it just wouldn't go into reverse and it was leaking a little bit too.
I took it in to get the tranny serviced because the cooling lines were leaking, so they repaired those as well with a leak in the pan.
The new tranny fluid helped a ton. It was a hardened seal that was just made worse by the dirty transmission fluid.
Maybe you need to get a new seal, or maybe just change your tranny fluid

I have the same issue with my 1998 I just purchased. It was bone dry when I got it a month ago, just started. Any ideas why now? Any estimates on repair cost?

My ax15 started leaking one day after a off road trip. Turns out it was leaking at the joint between the intermediate plate and the rest of the tranny. Basically the case was a throwaway because no one would take the core on a rebuild. Put a brand new one in for about $1700.00. It seems the old one was defective from the factory (bad cast) and it just snapped all the way through at about 105,000 miles. Hopefully, that's not what you have going on. Hopefully just a seal or even TC Case (much cheaper than transmission). Here's hoping hoping it turns out well!

(and yes, I made certain another person here on the forum got good use out of the rest of my old tranny which shifted very well)

I noticed in the pics that you posted that your transfer case shifter linkage is not hooked up, whats going on there?

i my friends shop removed it so that i wouldnt use the 4x4 because i re geared the rear d35 from 3.07 to 4.11 and im in the process of getting my hands on a 4banger front end so I have matching gears. they said id be irresponsible and wheel with the different gear ratios. i put it back on the other day because it was greasing up my glove box im going to take more pictures tomorrow the one i uploaded was 3 days old

Redline MT-90 from Summit Racing is about the best you can get for the AX-5 and AX-15. Aisin also added synthetic 10W-30 to the list of acceptable lubricants. Royal Purple 75W-90 is ok too.

For those wondering how both a 10W-30 motor oil and 75W-90 gear lube can both be acceptable, motor oils and gear lubes are measured on two different viscosity scales and both are essentially the same viscosity in reality.

Ha just saw this and I know it's too late but sure, that viscosity would be fine.
