How to determine data from a torque converter?

Hello,

Can anyone tell me how i can determine data (stall speed) from a (new) converter that i have laying around?
There's nothing written on the converter itself.
Can one determine / estimate based on thickness, diameter, or other variables?

thanks.

install it and find out that the only way I know.

^^^^^What they said. I like coll40's better because then your converter guy can make it what it needs to be.

hmmm....
thats a bit sad...
i think i'll go for the first option, and disassemble / replace it when it's NOT what i want...

i'd want to know a little about the converter before i went to the trouble of tryen it out.you did say it was new so it should be pritty safe but i've saw cheap converters scrap a good trans.

I agree. It is pretty cheap to get it checked out. Most any converter company can check it out and make adjustments.

Just overlooked the converter.
It's ingraved with "F49" , then painted turquoise.
With a permanent marker there's written " DF 5/6 LS" on it.
Do these numbers mean anything to someone?
Tried google, and comes with following: "E4OD/4R100 12" 1.375 PILOT,89UP,LS, LU, 300,460 ENG DF56LS"

Does this mean a stallspeed of 1375 Rpm?




When i'd have it checked, how do they do this?

Thanks.

Are you looking to use this with a C6/BBF? E4OD/4R100 transmissions are like a C6 with 4 speeds, and came in trucks & vans, but I'm not sure if the input shafts match up. I'll let someone else chime in there. Your numbers show a 12" converter, with a 1.375" pilot, which is 460-compatible, and I'm pretty sure the LU stands for "lock-up", a feature used only by the E4OD/4R100. Again, that may make it incompatible with the C6 also. And finally, it's for 1989 and up overdrive transmissions.

Hope that helps

Doesn't really help, but thanks for the effort taken.
It's not for a C6, it's for a E4OD that i plan to put to my 466.
The converter sat in it, so it fits..
I only need to know the specs of the stall of it..
I "think" that the LS stands for "low stall" , but how low exactly isn't mentioned unfortunately.

I would suggest you get it checked before you put it in. Those transmissions are to big and heavy to be putting in and pulling out . IMHO! Good luck!

That's what I figured. A way to find out is to spin it by hand until it locks up at like 1800 rpm's or whatever. Might take some effort but have a buddy sit and watch the revolutions. I wish I knew too, I'm in the same situation but I'm just going to get a new one. I don't feel like having to pull it back out because its not what I wanted, your best bet is to get a new one. Might not be what you want to hear but you'll probably thank me later when you go to do a burnout.

I'd venture to guess being 12" it's pretty mild, 1500-1800 is pretty typical stock stuff.

that is my thought also.
olnly thing is, when i run 1700rpm highway cruise, just up to stall, won't it slip just a bit and generate tremendous heat?
I thought that RPM in lockup always should be past stall Rpm?
