Transmission oil addative

[jperickson2001]

I just wanted to pass this on to you guys. When I swapped clutches I drained my tranny oil and tried that Lucas oil conditioner mixed in with the new oil. I always wanted to try the stuff because I have always played with the display at the auto parts store where they have the three gears on a crank that you turn so you can see what the additive does and how it reacts with the moving parts. For lack of better words, it elasticises the oil, allowing it to stay on the parts. Centrifical forces does not sling it off. It clings on and stays on the moving parts without being just an ordinary thick and heavy oil. Anyway, I did a 30 to 40% mix of Lucas with my regular synthetic trans oil and I can't believe how it operates now. No gear noise. No play. Silk smooth shifts in when cold or hot. If you drove my car you would swear it is a new transmission and not one with 115,000 miles on it. I would have used this stuff YEARS AGO if I knew how well it worked. So I give a big thumb up for Lucas oil conditioner. -John

Don't confuse those gears in the NAPA store with your transmission. Thicker is not always better. I would have to think that Tremec, Toploader and others have done there homework and know how best to lubricate their transmissions.

John -
What transmission do you have and what lubricant are you mixing the Lucas with?

[jperickson2001]

Bob, yes I am sure that manufacturers know what is best for their transmissions, but I like RESULTS, and I also am a disobediant little bastard and am not afraid of experimentation. A 30 to 40% mix of this product into the factory recommended synthetic oil doesn't faze me at all. If it blows up, I'll replace it. But I know it won't because of the way it's behaving. It's a personal experience type of thing. It may be thick out of the bottle, but remember. It is being mixed with the rest of the oil in the tranny. It really thins out and elasticises the whole batch. I wish you could try it out, but that would go against manufacturer dogma though. Sorry. Cheers.

John,

What transmission do you have? Inquiring minds would like to know.
I'm tempted to try it.

Interesting footnote I came across when I was rebuilding an Austin Healey trans with overdrive. It said the 'planetary type' gear system for the OD would act like a centrifuge and separate oil additives from the main trans oil. Of course thats a really weird OD system and not normal to USA products, it's an English thing...

Ford sells a 'friction modifier' for their limited slip differentials. it works great in a 40+ year old top loader.

Hi John, I want you to come to breakfast tomorrow but I've heard the world class T-5 has small oil capillaries that a high viscosity oil cannot penetrate. Supposedly, that's one of the reasons the original T-5 used gear oil and the world class uses ATF. A tranny tech., master mechanic, told me you could add one quart of 30 weight to a world class and not damage the transmission. So like my hair, keep it thin.

When I got the car it had trans oil in it, and I assume it had it for 6 years prior. Don't know if it's world class or not, but I know that for almost 9 years now it has run in oil. When I switched initially from regular oil to a teflon based synthetic trans oil, it shifted much improved. When I switched recently between the teflon based synthetic oil to synthetic mixed with 30 to 40% Lucas shifting is off the hook. It's not as much a heavy oil as it changes the lubricant you are already using to stay on the moving parts and not come off. Dave, I'll let you drive my car around the block if you want so you can see for yourself that it's off the hook. -John

Please, sir, I'll ask again - what transmission are you running?
