Ok guys n gals as I'm in the final stretch of buttoning up the new motor and tranny I need to find a kickdown cable. Does anyone happen to know which one to get or possibly have an extra they are willing to part with. Also do you have to have one, I dont plan on driving the truck hard or anything like that just normal short drives around 30 miles or less.

 

Well, they do sell them around, but I don't think you'll really need to have one unless you really want another thing to get in the way.

On your C4 the transmission will kick down all by itself just sensing the vacuum differential when you step on the gas.

I didn't install a kick down on my C6 behind the 390. The transmission shop that built it up said I didn't need it and I don't - it kicks down just fine without one - yours will to.

 

Engine is a 289 and tranny is a C-4...

 

Hi Tard,

I saw that on your signiture after I posted the question, then edited my post. You're quick tonight!

See the new answer above!

 

Ok another question for you then Julie. I noticed that after i filled up the tranny with fluid that it has a small leak where the shifter/kickdown linkage hooks up, is there a reason for that?

 

Not that I know of! You didn't overfill it I hope. Did you prefill the torque converter?

There may be some seals in there that are just a little dry, maybe when they swell up a dash or warm up that first time they'll stop.

 

No as far as I know I didn't overfill it. I emptied out the torque converter and put 1 quart in it as TCI said to do. Then once I got everything ready to go I put 4 quarts in the tranny, then I started it and added 1 quart at a time untill it was full. I think I ended up putting close to 8-9 quarts in the tranny but I was told that 3-4 quarts would end up going into the torque converter...

 

Ok, Yeah that sounds good. I didn't realize you had started it up.

 

sorry ot pls checkout my movie julie thanks

 

Oh yeah, started her up and have moved her around abit. I'm taking it kind of slow on the break in. I have been doing it in baby steps, the first time she started I got her up to 120 degrees, then went up to 140 and so on untill I hit 180degrees checking for leaks and stuff like that. Now I just need to work on getting an exhaust on her and putting her back together for next months cruise night...

 

Pull the linkage arms off and replace the - O-ring. An easy job. JIM

 

If replacing the o ring does not correct the leak you may want to check for the correct shift lever that goes through the trans case. I bought a C-4 on line from a transmission rebuilder in Fl. I had the same problem and after replacing the o ring a few times I discovered that it had the wrong lever in the trans and the o ring wasn't seating. It seems that there are two different length shifting levers depending on the year of the trans. It is only about 1/4 of an inch but the o ring will not function. I now have one from a c5 trans in my c4 and it does no leak.Upon talking with a trans shop guy who knows c4's he said in the day they would carefully fill off the excess and carry on.

 

Did you run it for the 20 minutes at idle to break in the cam? Also, it may get warmer than you think it's supposed to until it loosens up a little!

LOL, I was afraid I was going to break mine by driving it too!

Where can I find it?

 

yea I've ran it for probably 20 minutes or so each time well at least the last 3 or 4 times. I still need to get it in time but I think I may take it to napa once I get it back together enuff to drive it. I'm hoping to get the exhaust on this weekend then maybe I'll take her around the block once or twice dozen times....LOL
