removing 'kick-down cable' on TH350

Jim Johnson · Nov 4, 2003

I currently do not use it, and it has been cut off about 6" up from the transmission.

I currently have a leak coming from the cable ( dripping on front driveshaft). I just put on a TCI Aluminum Trans cover, so it is not the trans pan leaking.

I removed it ( kick down cable) and put some red RTV silicone around it and it is still leaking, also it had a crack in the plastic where the bolt hole holds it to the transmission

Can I simply remove it and plug the hole?

The answer to your question from what I have been told is yes you can remove and plug it. This what I have learned from a few tranny builders I have inquired info from. Good luck!

are you running a manual valve body?
do you care about trans life?

its not as critical as it is on a 700, but deleting it will shorten life unless its full manuel.

AFAIK, unless you're using a full manual valvebody, isn't having that important to tranny longevity? Something to do with line pressures and such..

You are fully manual right?

Otherwise:
1. It can drastically shorten tranny life
2. Wouldnt you want it to downshift when you mash the pedal?

remove the kickdown and put a small freeze plug in it's place, I've done that before for somebody that shifts manually. it is only for kickdown, the modulator does everything else as far as shift patterns go. It is still on the road after 4 yrs.

yes, you can remove it and plug it

On TH350's it does nothing to affect line pressure or tranny wear, but it will on a 700R. And you do not have to have a manual valve body.

I currenty do not have a manual valve body, however the truck still down shifts when needed.

I am sure this thing served some sort of purpose, I just thought I should see what you guys thought before I go to taking it out.

Is there anyway to remove the wire/cable.....it is only sticking out maybe 1", but it is still connected.

Sorry to sound like a dumba$$ - But I do not know squat about a transmission.
I just hate to screw up my trans over a small leak. ( generally my luck - fix one small problem and create a bigger one)

Why not just get a new cable and hook it up? They're only around $13. I find it hard to believe your trans will downshift when you floor it since that's the one thing the cable does.

Jim Johnson · Nov 4, 2003

If I did replace it ( which I might)....where does it hook up? sorry if this is a stupid question, But I don't know

This is a trail only truck, but Yes - It does kick down when I need it to.

It connects to the throttle lever on your throttle body or carb or wudeva your gas pedal connects to.

TH350 has in fact a "detent cable", not a Throttle Valve Cable". So it's perfectly OK to remove it.

Seems to me that the detent cable does have some control over shift timing. I usually run full manuel but once my Mom had her car transmission overhauled at Ammco and after that it would shift to late at full and part throttle. Like 6500 RPM was the wide open thottle shift point! Course they denied it said it was normal to shift then... Took them for a test ride and the manager then knew that 6500 RPM was not the proper shift point for a Buick V8--this thing only revved that far cause it had a full race tune and cam set up for drag racing. So I got the car back and all they had done was adjust (rigged) the kick down so it did not full so far. Well now we had 3000 RPM WOT shift points (too low) and a slow delayed shift. I had brought the car in with 5500 RPM shift points and told them to leave the valve body alone. Needless to say they messed with it and what ever they did did not work with the shift kit that was in the car. After bringing it back a few times and all they did was adjust the cable--well I could have done that...I bought another shift kit and shift point kit and we did what they had undone. This Ammco shop ripped my Mom off as far as I'm concerned. So I'd recommend keeping the detent in if possible. From my experience leaving out the detent will result in early part throttle and full throttle shift timing.
