Identifying this torque converter

[spross86]

I need some help with identifying this converter I just picked up today I can't seem to find a manufacturer's name
It's a 10" converter that came with a used 2004r and a Spare D5

Looks like an Art Carr 19930. I think it's a non lockup 9".

Thanks for the info! I just sent the info over to Art Carr to get the specs. Looks like I will be trying to trade this one for a lockup as its both street and some strip use car.
I really don't know how well it would do on the street.

I've run this converter on the street for years with no issues in my TTA. I run a large transmission cooler. The PTC NL is the one to buy but the Art Carr 9" helped a lot of us reach the 10's back in the 90's. Today I would buy the PTC NL. I wouldn't buy a lockup converter unless your car is only highway driven.

Thanks for the info. So if I run a NL converter do I lose the overdrive? So it's basically a 3 speed trans?

You will still have a the same 4 speeds you do now. The difference is that at highway speeds the converter locks up with the engine now. It's a fluid lock that makes the slip minimal. This will not happen if you change to a NL. On a stock car the lockup function drops RPM by a couple hundred and will increase your gas mileage by about 1 mpg. With a proper set up NL converter your highway RPM will not be that much higher. The NL converter weighs much less too, about half of what a stock converter weighs. It will have more slip with the NL so you need a good tranny cooler to keep the transmission temps down.
