4.2l TF 999 Kickdown cable issue

I bought a 1990 YJ with a driveline out ofan older CJ (4.2l 258 CI amc with no emissions and a TF999 or 909 Tranny) and it was missing all the tv/kickdown linkage. it has a holley 4 barrel on it with an aluminum intake and i cant find anything online that might work for it, any ideas, anybody know where i can get the parts i need? does anyone have any of this linkage? can i drive the jeep without it?

Is it an offenhauser intake? The carb linkage pulls towards the valve cover? My jeep is the same way and same trans. I just put a bolt in the linkage for the trans to hold the shift point at 1600 rpms so it always shifts at that point. You can buy a linkage though, just Google tf909 or 727 shift linkage. I was going to buy one but my jeep runs fine the way it is and its been like this for over a year, no problems at all. Even towing a trailer and driving across Texas

Yess i believe it is. The after market linkage will even work with the 4 barrel and the AMC straight six? I have absolutely nothing on the tranny for kickdown linkage now so hopefully it's complete. I'm trying to make this thing as right as possible. As long as those linkages are the same and will work ill order one of them

They talk about one made by lokar on here, but it seems to be discontinued because every time I find a link it says page not found

I had the same problem...was never able to find one from parts suppliers, i must have searched every one that could have been googled and had no luck on ebay. I had to custom fab a rod that connects the carb linkage to the T.V. lever. It was not to bad once you get the angles right and make sure it does not bind. I also built an adjustment into it. If you drive without one or it is not adjusted right it will toast your trans.
The problem with most of the aftermarket kits is that they are for the more common setups live chevy's that PULL the tv lever ....the Tf999 lever is PUSHED.....but.....the tv lever moves very easy ,so i dont see why having a cable push it wouldn't work. Seems many people have used the cable meathod and had success....I chose to make a rod, and it works great fo me

If I bought the old stock linkage used off of someone would that work with the 4 barrel?

no, i have the linkage and it won't work with the four barrel.

you can drive with the linkage pinned or bolted in place like i am doing, it won't fry your transmission. you just have ot make sure its set so it shifts at a good rpm and remember you don;t have a kick down. if you try to drive without setting the trans to shift, then you will fry it.


i am not the only person doing this, i got the idea from some buddies who have been doing it for about 3 years longer then i have and their trannies are fine

A cable could probably be fabricated to work but it didn't come with a cable, at least on any one I've ever seen. It's a metal rod with a couple bends that connects from the throttle to the trans.

the linkage works with the motorcraft, weber, and two barrel holley carbs. the carb just has to sit so the throttle arm is on the driver's side for the linkage to work. even my cruise control worked on all the other carbs but the four barrel holley. its the only one that i cannot find an adapter to turn it the right way
