Was talking to a guy recently about Mopar Transmissions and Converters.

He told me that Mopar only made 1 Converter(Stock)and no performance converters

He tells me that any performance Torque converter in the aftermarket(Stall speeds, ect) is actually a Mopar external converter with General Motors internals.

Anyone heard of this? How true is the info this guy is telling me?

Sounds a little far fetched to me.

You can't believe everything that some random guy might tell you - that's certainly not the right way to get knowledgeable on a subject. Mopar made many different OEM converter configurations, some that were excellent hight-stall street units. In fact, Mopar was a pioneer in the field of performance conveters.

Just like in politics, you can't believe everything that you hear.

I know this,and ya know I wanted to argue the point,but hes older and more experienced,knowledgeable than me,and im sure he would have whipped out some info that I wasnt aware of as a technicality,and then id just stand there like and perhaps not have any ammo to throw at him.It would end up as because noone else I know in our car group is into Mopars,and I wouldnt have anyone to back up my statements.This guy is supposed to be "the man" and he is looked at that way by many in town regardless of what they drive. I know Cordobas are B bodies. Fury and Monacos are big and I know that after a certain year they became B bodies. I just try to steer clear of this guy as much as possible.

In one sense, all the major automakers sourced parts from outside manufacturers. Sometimes identical components, wound up on different makes. That said, sounds like he is generally full of it, and not just himself.

In future dealings, you could always find written proof, from several sources, that contradict what he has to say and confront him. Of course, he will continue to just dodge and weave and make excuses, but he'll eventually realize you're not so easily fooled.

You don't need to be Nasty about it, just factual. If you do it in front of other people, be prepared for a battle, as his ego will be on the line.

Now that you know he's really a false-expert, keep what he says with that in mind. If you suspect he's wrong, look it up or ask here.

If he's really that full-of-himself, others have or will recognize it. In the future, you could be cordial, but generally avoid him.

Over time, if you stick with it, read and look into the subject, you'll gain your own expertise. It simply takes time, but you're on the right track.

Your dude is wrong. maybe GM's used mopar internals?

So now we know that your expert isn't one at all,how about torque convertors?
What were the 'good'torque convertors?
Are there any 'dogs' to avoid?
Do torque convertors have part numbers?
Do the hi-po cars(r\t's six packs etc)have a hi stall convertor?
I must admit when i put my new engine in i never even looked at the convertor,so i don't know much about them at all.
School us please

I went from a "stock low stall tc" to a "stock high stall tc" in a lot of mopar trannys

mopar was good about duel purpose tc and depends on what it was in

thats why some mopar engines "seemed" hotter than others,with basicly the same out put at the flywheel

for example,my 85 318 truck came with a low stall tc

I went to a tranz shop and got a stock high stall tc for a 225-/6 engine

put it behind the 318,(same balance) idles 650 in gear and light throttle it stalls at 1500-1800 rpm and will flash to 2000-2200 rpms when stomped

truck is mucho fun to drive now

in the mopar catalog they are listed as duel purpose and then there is a race converter

this works the same for any combo,a 360 tc will stall higher on a 440 than the stock 440 tc

a hemi tc will not stall as high on a 440

it depends on how much torque you put in to one for the amount of stall that you get

I am no expert but I have swap a lot of tc and trannys,mix matching to get the results I want with out haveing to use after market high $ tc

more to it than you think,IMO
