And on these 9-10 spd trannys, I'll bet you'll never see one in a HD diesel powered PU. Too much stuffed into a small space can't possibly allow much torque.
???? The up to 18 speed transmissions in OTR trucks seem to handle 2000+ ft./lbs of torque pulling over 100,000 lbs. just fine. A smaller, fully automated version would work well in a pickup.
I don't think so. Those trannys are MASSIVE, as is everything else on an HDT. And they use a splitter to get 18 spds, not gearsets. And they're manuals, not automatics.
I just don't think the metallurgy and size constraints under a PU will allow it.
The Ford's 4R100 (100 for the 1000ft lbs of torque rating) is pretty big already.
