HOW TO: Change your leaky shift selector shaft seal with this $9 Tool Th350 Th400

www.napaonline.com/en/p/BK_77...
This was supposed to be several parts. But I had computer issues..
Fortunately I was able to save the most important video segment.
I am in the process of resealing the TH400 In the past I would drop the pan and remove the entire internal shift linkage to replace this tiny little seal.. My friend has the correct tool to do the job and he was nice enough to let me borrow it to do the job without breaking the seal. Installation is opposite of removal. I used a piece of rolled plastic to buffer the seal to shaft surface. It keeps the seal lip from rolling in on itself.. I was un able to show that process unfortunately. Anyways let me know what you think..

Finally someone made a video showing the actual shifter shaft seal removal tool in action! When I went through this none of the part stores had the removal tool in stock or had no idea what I was asking for. Good video! 👍

Typical of Auto Parts stores these days.

[@MEANGENE]

Honestly that's the first time i seen that done thanks for the demonstration👍✌

CRRRAAAAAAPPPPP! Been chasing removing my seal with a POS china knockoff, was about to pull the pan and LO! Didn't even cross my mind to TAP it in to start the threads!
THANKS!!!!

Thank you for posting that video and the tool link. I just purchased one for my 68 el Camino.

The film is likely used to protect the new seal from a corroded or rough outer shaft while being installed. I use that system when putting new seals in my dirt bike forks, for example. It protects the seal lip until it gets on the inner shaft's smoother surface.

[@tbahry202]

Also to protect from the flat edges where the linkage arm goes....

[@demartinsm8479]

Did you lubricate the seal before you put it in?

[@searchneverend]

Does this applies to a 1997 Camaro V6 with 4L60E transmission? How did you remove the gear selector cable? Thanks

[@jamesgibbs2416]

What’s the part number for the tool and the seal part number for an E4OD seal?

[@bluegrasskid]

What size wrenches are you using sir?

[@cj7girl280]

Anyone know the nut size for the th700r4 gen 1 transmission selector shaft? I can't find mine..

[@cj7girl280]

How do you take the selector shaft out? The threads are all chewed up... Need to replace it.. Does it just unscrew once the seal is out?
Thanks for the video...

[@Tryalittlebit]

Will this tool work on other cars? Provided I get the correct size

[@Mattys91gt]

Would this work on a Ford aod

[@lauradahlus]

My shifter shaft in my 700 r4 tranny pops in and out ever so slightly... would you know why it does this and how to fix it? I need it to stay putcso I can install my bandm shifter to it..
Thanks for the video..

[@cj7girl280]

Don't forget to lubricate the seal with tranny fluid b4 installing..

[@mooosestang]

omg, do they make one for a ford cruise-o-matic? This looks a lot easier than dropping the pan, but i'm guessing you'd have to drop the transmission.

[@brooksstewart4707]

Has anyone change this seal while in the car? With headers??

[@HEYBERT1984]

Much obliged 🍻

[@jf8461]

I wish it showed the direction the new seal is inserted. And what is that sheet film for??

[@stevem3409]

Apparently everyone knows but you and I. 🤷🏻‍♂️I get the feeling he’s gonna try to sleeve a worn shaft?

[@fingerz6983]

Put it in same direction as old seal , he just cleaning the crud out before put new one back in

[@mustangpassurchevy]

You always put a seal with the lips facing towards the pressure side. So the lips would go in

[@schutzhund3933]

The early th400s use an o ring seal, gotta pull pan to replace!

[@everestsdriveway366]

Yea that’s what my 67 Cougar has, just got it and it leaks from that piece, so gonna have to fix the leak.

[@nathan65071]

[@derekscarr9856]

[@raydavis9261]

[@stevem3409]

The hell the plastic for?

[@beeterolds]

???

[@andyburk4825]

PRotects the new seal when u slide it over the shaft - the flat corners can cut the rubber, he didn't show this however.

[@oldmanmtb1443]

I got the same tool for some reason it will not fit the way you did it, it just wont go in...4l60e

[@schutzhund3933]

Same here. Wouldn’t fit over shaft

[@strengthfortoday]

Rottboss Schlll did you get the job done somehow? Please help!

[@strengthfortoday]

How did you get the seal pulled?

[@oldmanmtb1443]

@@strengthfortoday i use a small flat head

[@strengthfortoday]

rusty watts did you insert it in the outer edge or inner?

[@_Ramen-Vac_]

just accomplished this with a 2$ 90* pick tool. You're over-complicating chit, mang.

[@beeterolds]

Well good for you

[@raydavis9261]

Paid 6 something for the seal
