YJ manual transmission change

I was told by someone who worked at a local lube place here in Indianapolis that in order to get all of my transmission fluid out of my car they would have to hook my Jeep up to a maching and they would pump out 8 quarts of fluid and put back 8 quarts of fluid. He went on to tell me that I could do it on my own, however it will only drain the 4 quarts out of the tranny itself, and there is 4 more quarts I can't get to. Is this true or false? Should I just pay the labor and have them do it? or do it on my own?

If you have a manual they are full of sheite. Just pull the drain plug, empty it and dump 4 quarts of 10w30 in it. You are good to go.

Yea that sounds like they were thinking of an auto tranny where fluid would be "stuck" in the torque converter.

You have the AX-5, right? The fill plug is up on the passenger side of the transmission. It takes a umm... 17 mm wrench or something to remove it. The drain plug is down towards the bottom. Don't remove the upper plug with the torx head, that one isn't for removal.

An easy way to fill the transmission is to remove the shifter assembly and fill it through the top until it starts trickling out of the fill plug hole, piece of cake.

The guy you talked to either thought you had an auto, or doesn't know what he's talking about.
just pull the drain plug, and as TheDustMan mentioned, it's easier to fill it by removing the shfiter.

I think thats what the manual recommended but many of us use 10w30 engine oil. It warms up faster, shifts smoother, and doesn't have chemicals in it that tear up the synchronizers like gear oil does.

Well, I'm not sure about the AX5's, but the jeep part number for the proper lubricant for the AX15's, is for 10w30 motor oil.

The shifter assembly on the inside of the Jeep? So I can fill the manual transmission fluid from the driver or passenger seat?

Yes, take the boots off and then pop the retaining collar out and you can pour the oil down through the shift tower.

The shifter assembly in the ****pit of the Jeep?
lol, it blanked out ****.

And yes, in the cab. Remove your shifter boot assembly and then push down on the retainer while turning it counter-clockwise (I think, might be clockwise) then once the retainer pops out, just pull the shifter assembly up and out and you'll have a nice opening where you can just add the new oil.

This is a great idea, except I found it was a pain in the arse to get the boot back on :P
