Hello folks,

transmission builder is finishing my 904 and I told him that I wasn't planning to use the kickdown. He was very upset and said it´s mandatory to use it.

Sorry my ignorance but is this true? Wha would be the issues of not using it?

Car will be street/strip...


Thanks,

If you are not using a manual valve body then yes, it is mandatory otherwise front clutch failure will soon follow.

You need to understand that kickdown is an incorrect name for the linkage you are talking about . It is actually throttle pressure linkage and that tells you why it's necessary. It actuates a valve in the valve body that adds pressure to the system as you increase power to keep the clutches and bands applied rather then slipping and burning up. With out that linkage the trans will fail very quickly unless you have a manual valve body in it.

TF2 Don’t matter, you will be pulling it out after 200 miles or less. You have been warned.

you need it, if you don't have it, you'll blow your trans. if you don't want to use it, you need a manual valve body

Shift kit DOES NOT replace the linkage.

You don't have to use the TV linkage. But when the trans takes a dump prematurely, you'll wish you had.

The TF-2 kit gets good reviews & I think with an adjusted correctly kickdown & the largest cooler that will fit in front of the rad that you will be good to go.

FWIW, I ran my car years ago without the linkage; it was not installed when I took ownership of the car. Best guess, the rebuild had maybe 3-4000 miles on it. I built another motor and had the tranny re-freshed at that time. My low/reverse band was burnt up. There were a few other small parts that were bad too but, it's been so long, I can't remember.

At the time, the tranny was not doing anything stupid, I was just going to put some more power to it and had it out so; I thought it was an opportune time to have it gone through.

If I can remember right, I put a couple hundred miles on the re-build without the linkage too. At that time, I learned of the importance of the linkage. The car was my dad's and my brother still owned his house so; I pretty much knew where all that stuff was. I went to my brother's house, located all the parts other than the bell crank (I bought that used of E-bay) and I installed it all.

I have probably 6000 miles on the tranny without issue.

Why? The transmission guy was right. Do you abandon someone that gives you correct advice?

If you want a more exact throttle pressure linkage without the rods use the Bouchillion cable kit along with their throttle cable bracket. I have used them multiple times over the years with great success
If you want to ditch the linkage you may as well zip tie the pressure wide open and go

Doc F, don't be giving wrong advise about the KD linkage. It is necessary unless it's a full manual automatic.

Doc is backwards again. The Trans guy said it was mandatory. I agreed. Where is the confusion?

I picked up on where Doc was going with it.
He was being sarcastic about why the OP would be questioning his trans guy's intelligence.

To BullBob and the rest ! ..., no sarcasm on my part !! ... jsta total BRAIN FADE on my part ! I misread it..... BIG TIME.

BUTTT .. You CAN drive without KD linkage if you tie the lever back about a third of the way ..., if you drive it EZ. Do thatt - then put in a WANTED AD back in the swap meet section here and get the right OEM parts. I have never used a cable set up .... I’ve heard mixed reports about that setup....

FRANKENfurter ... I’ll EAT CAKE on this one ! coffee
