PK numbers

No, I know of 2 b&m "tork master" converters that are brand new I was considering. One is here in our classifieds for a better price than I found the 1st one for. Not a lot of difference between low stall and hi stall then
the converter I was looking at won't work as it is for a non lockup trans , so the point is moot.
Unless I find a different trans, but there is nothing wrong with my current one except for possible ring gear damage.
I just figured if I can find a decent aftermarket one similar to what I mentioned here that would work for my unit, why not? I guess it's back to a rebuilder's special, as I ain't paying $600 for a converter. I have one for a 518 here that would actually work, now that I know that mine is a lockup version.
The A518 may or may not work. All 518 converters have a number stamped on the pump side(hub side)body of the converter. It will be 3 numbers, and these numbers are stamped by the factory. Examples: 875/595/642 and others. Get me the number and I can give you more information.
Do you really need a High Stall? You've made no mention of what engine and what has been done to it to need a high stall.
