Rediculas thinking the AISIN has anything to do with acceleration because of harsh 1-2 shifts. HARSH is a subjective term. If you want a trans that slips easily from gear to gear then the others may be for you. Simply put firm shifts cause less wear. REAL answer is the inline 6 is not a screamer and the 3.42's ARE going to net slower acceleration.
The Aisin is a slow(yet firm) shifting transmission. It wants to lock the TC in gear and holds it for too long. This and the high stall speed of the torque converter has a lot to do with how slow it accelerates. This is why the 68RFE trucks out accelerates the Aisins even though they have less power. It is a work horse, not a stallion.
It's shift strategy is not the best either and struggles to put you in the right gear for the situation just as PUTC stated in the towing section. The same can be somewhat said for the 68RFE, but at least with the 68RFE a good tuner can alleviate that problem.
You keep saying this, I have owned BOTH and the AISIN runs like a built auto. I like the solid predictable non flaring shifts. ONLY thing I would change is to lock out the low 1st gear when running BobTail.
Not sure why you call it a "slow shifting" transmission??? I can floor it and it hits 3K or very close to it gear after gear. Nice n solid!!! NO slop.
