A6 torque converter question
Hi all, I have been a transmission builder for 30 +, I am trying to find out why I have to buy a C6 specific stall converter when on a stock rebuild they use the same converter as a truck with a 6,2, my car is an 2011 grand sport, a6 6L80, LS3. I have measured the dimensions and they are the same as a standard 6L80, I am just looking for a 2800 stall and can not justify 1000, for a c6 specific converter. and ideas and explanations would be so greatly appreciated. Thanks

Thanks for the responce guys but the truck was an example I used asking why a standard 6L80 converter would or would not work, The 6L80 is in camaros, G8, etc and thos converters are less than the vette converter, starting to think it is just a vette TAX!!! If I decide to be adventurous I will post back how it worked out.

GM / OEM converters for Corvettes, various GM trucks, Camaros or anything else that has a 6L80E transmission is going to be approx 1,600 rpm stall max. No sense in replacing your stock converter in your C6 with something that has the same stall speed.
If you want a converter in the 2,800 stall range, you are going to need to go with a Yank, TCI, Circle-D or a Precision.
Also, these aftermarket converters are smaller in diameter and have a very strong billet clutch disk in them ... they will handle much more HP than the OEM converters without ballooning.
BTW ... You don't need a more expensive multi-disk converter unless you are going to lock it up at WOT. Most street driven cars only need a single clutch disk converter because the only time they need the converter locked is at a steady cruise speed.
I can tell you for sure that a converter in the 2,800 stall range will really wake up your C6 without loosing any driveabilty in stop and go traffic. It will launch like a rocket! .... But, go too high a stall and the converter will feel 'sloppy' under normal city driving operation.
Anyway, it's all up to you.

I had a Yank SS3600 in my old 2000 Camaro SS 4L60E and it was fantastic and the street with normal driving(and spirited of course). With the A6 in the C6 I really didn't even consider that stall would be a good option.... I'm thinking I might have been wrong. I do wonder since the gear ratio is smaller between gears if running a lower stall might be the way to go... folks seem to be suggesting the 2800.

The C6 6L80 converter will NOT work in a truck, or vice versa, as they have different brackets, since the Vette converter doesn’t bolt to the flywheel, but to a small flex plate at the rear end of the torque tube. The case of the Vette 6L80 trans is different as well, in that it doesn’t have a tail shaft housing and has a very long output shaft that connects directly into the differential housing. The Camaro and truck 6L80 converters are the same and can interchange.
As for the pricing, I would bet it’s more supply and demand why there’s a difference, since I’m sure that the truck/Camaro converters sell in far larger quantities than the Vette converters.

I'm no expert but I suspect the truck converter is deigned for a vehicle that is 4-5K lbs. I bet that even if it did bolt up, a truck stall in a vette would feel very tight and not behave in an ideal way.
