As I understand it, the torque converter is used to apply some slip when needed between the engine and wheels. But isn't this what the transmixer does? Could not the transmixer be designed, in and of itself, to do the same thing? Why not simply combine these two into one component? ???

just like the line in the movie JOE DIRT-

"How does a posi track in a plymouth work?? IT JUST DOESSSSS"

Enlightening.

 

I'd like to address this, but I have no idea what a "transmixer" is. The TC does 2 things, 1. provide a fluid coupling between the engine and transmission, substituting for a clutch, and 2. supplies torque multiplication while it is "slipping". Number 2 isn't as much of an issue any more, with lockup convertors.
Maybe this will help:

I too was wondering what a transmixer was, so was watching to see if anybody chipped in that had the answer. Sounds like something from a sci-fi movie.
Agree with your explanation of what a TC does.

 

transmixer ??? ??? ??? ???

 

Hmm, my bust everyone . . . I use "transmixer" as a synonym for transmission.

 

The AT in the RAM is a 4 speed transmission. The torque converter is not really a clutch that is slipping, but a kind of hydraulic variable transmission. (OK, there are some losses in it, but the goal is to transform the input shaft torque into output shaft torque, if at low speed the converter ideally converts 2 crank revolutions @ 300lbft into 1 input shaft revolution @ 600lbft- hence the name torque converter)
Since this process can not be done effectively over the whole desired bandwidth of speed and pulling force there is a transmission geared to dive you mechanical advantage in 1 and 2, sacrificing speed, a direct drive in 3rd, and a gearing to give you speed advantage sacrificing torque in OD.
There should be no slippage involved in the powertrain. Naturally there are some slippages and losses during shifts and in the TC there is also some loss of energy- there is no 100% conversion. To reduce fuel consumption there is a lockup clutch that makes the power bypass the torque converter.
The slippages you read about on this site are usually either defective transmissions or poor trannies overpowered by the torque the bombed engines throw at them.

Just my 2c
