Lenco oil

What type of oil are you using in a cs1 3 spd,
in my 2spd i used atf, but have since been told that it would go through clutches for fun, any ideas?
Also is a titanium can ok to bolt the three speed to without supporting the lenco, as it is a lot longer than a two speed and heavier, with more leverage,
i do over-engineer sometimes
thanks

 

We use regular 10-30 oil, that info comes right from Lenco. Clutches always look like new.

i always ran atf and never hurt anything in a lenco. as for the ti-can supporting a 3speed, I don't know of any funny car that has trans mounts.

 

Lenco

Never used a trans support with a ti or steel can, every thing in one of these cars moves so much i doubt a rear mount would survive . We always use motor oil, 30w, 10w30 always looks new.

 

atf will give you a firmer shift but its not very good lube for ball bearings. When I used atf in lencos the bearings always felt rough but clutch life wasn't a problem. With 10w/30 motor oil everything looks new besides an occasional sprag, and I thing they'd be worse with atf. Some of the big dog powerglide promod guys use 30w hydraulic oil in their powerglides, it might be a option.

We use Mobil 1 synthetic atf in our 3spd. Lencodrive. Never hurt anything in over 3 years.

You know, thats what I've been using in my dads powerglide and I swear the convertor works better.

I cant post a pic or vid here but heres a link http://www.youtube.com/watch?v=gr91bkO7bjM with almost the same tuneup we've gone 8.25 166. I know this is a blown alky website so here; not real fast but fun.http://www.youtube.com/watch?v=8ENETW0cdvM

 

I like using ATF, it might not be as good for the gears or bearings, but I found that engine oil makes the sprags too slippery, so in a top alcohol car, it is more likely that you'll slip the sprag, usually resulting in severe engine damage.

 

Hey Ken:

Curious to find out how you discovered the slippage in the sprags? We they coming out blue or scored?

In the screw blown dragsters cs-2 I have seen some blacking( but very little) on the steels, like its taking the clutch pack to long to engage using 10w/30. I think Im going to put Mobil 1 atf in it next year.

Glenn are you using the multi vehicle formula. It really stinks like dextron did 30 years ago. I bet if there is a problem with the tranny you'd know it, by the smell.

I stopped using ATF 20 years ago when it dawned on me how flammable that stuff is compared to 10-30.

 

I sure dont want to sound stupid.But I am about to run my first Lenco CS -1 and the people I am listening to say to run the same oil as I run in the motor which is 70 weight.
Now I do know these guys know what they are doing so why so different from what everyone is talking about here.
Does it make any difference that we are running a converter drive rather then a clutch car?

 

This subject comes up pretty regularly and I am always surprised that no one suggests the Lenco brand oil.

 

I thought that they used ATF in automatic transmissions because it was more of a hydraulic fluid which helps apply the bands and such in an OEM transmission.

I didn't say atf did not lube bearings I said it wasn't as good of lube as motor oil. I've been building automatic transmissions transer case for 25 years manuals longer and Im telling you the first thing that tells you atf has about the same lubrication properties as water is ball bearings. It cools them though.

ATF WILL shift "harder"....We would show a drive sfaft spike! Switched to 5W39 Synthetic and never regretted it!

 

Since we are talking oil, does it matter which hole you dump it in?

 

I always put a quart in each gear case and a 1/2 in the reverser but they bleed over to eachother through the hole behind the sprag at 3/4 quart or so.

 

ATF gets out of the way quicker when the clutches and bands are being aplied type F grips better. The line pressure would be almost the same with ATF or 10w/30 motor oil.

above ;what I sais earlier; I run a couple quarts of redline type F synthetic in the Mobil 1 synthetic ATF(its some slick s..t) in my dads powerglide to make it shift fast

and

I split another Quart of fluid between the lenco cases for a long run (if im not going to take it back apart in the near future) . 3 1/2 3speed, 4 1/2 4 speed.
