TF-999 Leaking from Shift/Kick Down
Well, I was going to change out the gasket/filter today (TF-999) since I did see a leak around the gasket. Upon further investigation I looked w/a flash light and I am seeing where the shift lever/kick down lever is mounted, the gasket is leaking. SO this is where my leak is coming from, nice bright red fluid.

Question: do I have to drain the pan to fix this, or can I just pull the levers. I'm thinking it is like a through bolt and needing to pull the pan to replace the gasket/ring for these levers.

I did come across the manual below but it really doesn't go into detail about this (unless I didn't see it). Looking at the picture, it looks like if things are unbolted from the top side it should slide out but I'm not sure if the GASKET is just on the top side or is there one on the inside as well.

Any help would be appreciated,

How long has it been sitting?

Rollbar 04-30-2011 01:25 PM

Oh, about 6 yrs. Shifts well through out the gears (has a shift kit in it). I haven't had it on the road yet, still finishing up the build.

PM me your email address and I'll send you the parts manual. I believe there's an o-ring in there.

Rollbar 04-30-2011 01:35 PM

PM sent.

Thank you again,

Rollbar 04-30-2011 03:03 PM

It shows the seal for the "main valve lever" with an arrow from the top on an exploded view. I'll have to check it out to see if it actually comes from the top or from under inside the pan. To me and looking at diagrams like these, it should come from the top.

Thanks again,

Part # J812 6794

Page 1026

#17 on the exploded diagram.

Here is what a friend of mine set me from Fla. I don't quite undertand the whole taking apart thing, and he owns a tranny shop.


to remove and install seal without valve body removal :click:

i know you do not want to spend the $

with v/b removal

remove 10 bolts using a 7/16" socket

1-2 accumulator & park rod

park rod
must turn d/s to engage park and remove park rod with v/b from extension housing or fight with e-clip at v/b side not shown
(do not remove extension housing)

use screw driver and knock seal out from pan side.
use a small slide hammer with washers to install seal if no room.

I replaced that oil don't have to take apart the tranny to do it. It comes out from the top. After removing the linkage, I just used a screwdriver to pry it out, then used a socket to seat the new one. The seal itself cost 3.95 at Advantage Auto. It took me loger to get the linkage on and of than to replace the seal.

Rollbar 04-30-2011 11:20 PM

OK thanks,

You must have pryed it out from around the stem of where the linkage attaches.

I'll try it.

RjTack 05-01-2011 05:45 AM

Go buy the new seal to see what it looks like. There is a lip around the outside edge. If you can't get it out that way, you have to remove the valve body and push it out from the inside. You might be able to get to it with a small screwdriver, or punch without removing the valve, it's been a while, I can't remember if that shaft is attached to the valve body, or next to it.

rrtex1 05-01-2011 07:08 AM

You may b able to pull it from the top. Would need a tool with a hook on end to pull it. If not you have to drop the valve body and push it out from the bottom like the pictures show above. Good Luck!

Here is a link to the site where I found the TF999 parts manual, also added my CJ FSM just for good measure:

Rollbar 05-01-2011 05:12 PM

Thanks all, I'm going to get a seal and look @ it. I'll have to get the tool (maybe AZone rents them) and I'll do a write up.

We will see.

Thank you all again,

Rollbar 05-03-2011 10:15 PM

Well I picked up the seal from NAPA, and hopefully I can get to it next week. Real busy weekend coming up.

I'll try to post up some pics of the install if I can get my camera up in there.

Thanks for all the help so far,

jorns 06-18-2011 12:10 PM

Any progress on this ? I am having the same problem, but have no idea how to fix this.


Rollbar 06-18-2011 05:17 PM

Yes, I am waiting on the tool to come in so I can change out the seal w/out dropping the pan etc.

the tool comes as pictured. use the black tool to remove seal. install black part of tool over shaft and use wrench to turn black part of tool into seal. use another wrench to turn bolt into black part of tool to remove seal. use silver tool to install seal.

VACJ7 06-18-2011 07:27 PM

Can you post a part number and where you bought it? I may have to tuck one away for the future.

Rollbar 06-18-2011 07:48 PM

Seal @ NAPA.

Tool is $50 bucks on line but a friend of mine is mailing his to use.

I found the tool:

So you are saying that with this tool i can change the seal from the top of the transmission, and even dont have to drop the oil?

And AFAIK, this is the seal you used?

What about this part, i read that it was smart to change that i same operation, agree?

Anyone know where i can buy all this from one store? I live in Norway, and i dont think Napa are sending parts out of US.


Rollbar 06-19-2011 02:15 PM

Yes U don't have to drop the pan and on page one is the part/# from NAPA.

jorns 06-24-2011 11:07 AM

Anyone know where i can get this parts? Napa refuse to send parts outside of US.

The new seal is very snug, put it in the freezer for a while before installing it. I had to tap the old one out from the inside, I couldn't pull it out with a seal pick.

Rollbar 06-27-2011 02:06 PM

Thanks for the tip on the freezer.

superj 06-27-2011 08:27 PM

use a screw driver to pull that out. its just a normal old seal, like an axle seal. just hook the edge and flip it out or use a big bolt and thread it out.

The time now is 02:39 PM.
