Lokar Kickdown Cable Adjustment

Lokar Kickdown Cable Adjustment - 01/11/11 11:57 AM

Ok -- I've adjusted my son's 400/727 Lokar kickdown by pulling the slack out of the cable at WOT so he has full pressure at WOT. The tranny kicks down when the pedal is smashed, but the problem we have is it doesn't like to shift from 2nd to 3rd until about 3500rpm. 1st to 2nd seems ok around 1500-2000rpm. Cruising through the neighborhood at 25-30mph the tranny will not upshift to 3rd. Too much pressure at low throttle? What can we do to adjust the 2nd to 3rd shift point?

Have that cable in 'your' duster too with the 340. Have you tried giving the cable a tiny bit of slack at WOT? Could be it...

DUDE! How the heck are ya? How's the Duster doing these days? Any new pics or videos you can share with me? Damn I miss that car...

I have a Lokar setup in my Demon too, but I never let the tranny auto-shift, so I've never paid much attention to it in there. My son's RR is a daily driver and shifting at 3500 all the time is becoming a pain. I'll try and take some pressure away from it to see if the shift points drop. Anyone else?

Hans -- send me some pics and/or vids of the ol' Duster when you get a chance. PM me.

THANKS!

I agree - and give it about 1/8" of slack at WOT

To be honest with you, I'm no fan of the Lokar Cable. I had the same probs as you and it took a lot of trial and error to get it right. If you're not right you can cause probs. with your tranny. I'm switching to Bouchillon when I get my auto car back together. I had a talk with them last week and I think that's the way I'm going. They at least know what a Mopar is, Lokar is cool if your a street rodder or GM.

Thanks all -- and although I agree the Bouchillon one is superior to the Lokar, he already has the Lokar and can't shell out $130+ for the Bouchillon right now. I've thought about it numerous times, but money winds up getting spent on needs rather than wants.

problem with the lokar , from reading posts , is it's a generic setup and needs to be adjusted to work properly in a mopar application , the ratio of the throttle movement to the arm on the trans is not correct , takes trial and error drilling holes and moving the cable pin , which way and how much ????

just give it 1/8" slack and drive the damn thing first...

I agree with DJVCuda. I had the same shifting issue. Adjusted in some slack and issue was solved.

Adjusting for slack will only solve your problem at partial throttle. You will ALSO lose your high rpm upshift.

To have both an earlier upshift at partial throttle AND a max rpm shift at WOT.
You need to shorten the throttle lever on the transmission. Basically you drill another hole inboard on the throttle lever.

A shorter lever will give you more action or a bigger sweep for the same amount of cable travel.

Yes -- I backed it off some and it's better but not totally fixed. Trial and error...or $140 for the Bouchillon.

Have it on my 383. Backed it off a bit and it shifts exactly where I like it. Granny-driving it will go in to 3rd at a low RPM. Shifts on it's own at WOT around 4900 RPM's. I manually shift it a lot anyway. At WOT I usually manually shift at 5800 RPM's. Tires spin some, real firm shift, so it has plenty of pressure. Been driving it this way for years. Still shifts great.

Changed tranny fluid recently. Fluid looked really good even for being in there a few years.

have been using lokar cables for years and have never had a problem. i always set them up to short shift a bit when on the floor boards because i figure on the street where am i going to really wind it up to 6000 rpm over and over. if i want to really wind it up i'll shift myself. on the street i like it to shift at about 4500 rpm on the floor boards..

I have noticed that if you drill a new attaching hole in the kickdown lever about a 1/2-3/4" inboard of the original hole it helps the carb to lever ratio. That makes it work better and easier to get adjusted where you want it

Thanks all.

I ended up drilling a hole about half way in on the the trans lever and it did work better. I used a very old lever off a older trans that had more meat on it.

if you move the pivit point closer to the center it will move slower so it will not apply as quick on light throttle
