Transmission Fluid Change

I have a 93 Wrangler with 4.0 liter I-6 and manual trans. I just drained out my fluid and started putting new stuff in. I got about 3 quarts in, stuck my pinky in the fill hole, and dipped it down. I touched the gear oil but 3 quarts doesn't seem like a lot. Is that normal?

That's about right, I just filled mine last week. Took a touch over three quarts. Next time I do it, I'll just put 3 quarts in because I'm now running Redline MT-90 and that stuff is $8 a quart.

Alright, I was just making sure. Because it looked like 4-5 quarts came out, but maybe my eyes are off :P

I'm just trying to get prepared for my off-roading trip this weekend so I went ahead and changed all of the fluids in my Jeep. Thanks for your input though.

You can bet if you dumped it on the floor it would look twice that amount

I am amazingly clean when it comes to fluid draining. No automotive oil has ever touched the concrete of my garage :P

Duh, another stupid question..

Does it really make a big difference when you change the manual transmission oil? I have always heard that the oil in the tranny doesn't need to be changed.
I have seen a couple of comments about guys changing their oil over to a synthetic oil. Is it worth it?
For what its worth, my 5 speed has always been tight going into 2nd gear, ever since new, and would always give me a very slight grind if I shifted too quickly.
Now, 160 thousand miles later, it still does it...

Well I like changing fluids because it makes me feel better (and the fluid that came out of my transmission had the approximate viscosity of water...). I have noticed that it is easier to shift into first when slowing down and it has made the shift into reverse easier also. Synthetic gear oil will last longer, so yeah, it's worth it.

The dealer sheet specified 3 2/5ths quarts for the AX15 every 30k miles. Don't get thier stuff either, it's 14 bucks a qt.!!!!!!

Ah, yes good ol' Swope! Found that out myself about a month ago. I bought Valvoline synthetic from Autozone for $24 instead of the dealer's $45.
I can see where synthetic lasts longer, but I also keep hearing that it increases gas mileage, although the gains would have to be very small. I guess every little bit helps.

yea I was about to say it is close to 3.5 qts for the ax-15. I think that tight going into 2nd is an ax-15 trademark. mine is real tight on very cold mornings before she warms up

I guess I'll go back and put a little more in :P Thanks. And yes, second gear misbehaves, even when I yell at it.

I just had my trans overhauled, 2nd is tight when cold so I am going to try REDLINE MT 90, I have some on order now. It seems like the most recommended AX-15 oil on this forum.

I'm also draining the trans fluid in my Jeep this weekend and was thinking about switching to synthetic. But I get conflicting opinions about the switch. Some people say that is can cause leakage in the tranny for whatever reasons and others say its better for you trans because is more stable then non synthetic. I'm going to switch to Synthetic anyway but I wanted to ask, I've heard that the first time you switch to synthetic, that you should try some kind of blend instead of a complete switchover. Then the next time you drain the trans, then go all Synthetic.

is that a myth? Should I just go with a full switch?
