Message: [QUOTE="Charles, post: 642989, member: 103"] The Liberty activates gearsets via clutches and each successive gear is driven under power, with no lapse in forward drive on a shift. That is about as far away from a ZF6 as you can go without having a converter. I don't care if you use helical cut gears, straight cut gears, planetary gears or what, it's the same concept. The only true conceptual difference I see is that the gears do not "stack" on one another, in that the lower ratio has a one way sprag instead of staying applied and continuing to be pulled against as in a traditional auto, as well as a lenco. In this sense I think it's actually weaker as one set must hold all the applied torque. Hence the fact that at over $7600 for the base model it wouldn't even support a stock 6.4 powerstroke with a chip without exceeding it's rated capacity... And I realize that the ZF has poor cooling capacity. Hence the fact that they are no longer [i]offered[/i] in a superduty. I guess if you wanted to build a one-off pump assembly to move the needed volume, have a remote oil reservoir, oil thermostat housing and large cooler in addition to the OEM cooler then sure, you could get the temps down..... but you couldn't make the torque capacity go up. It would still hammer the input shaft bearing out of it, it just wouldn't scorch the fluid anymore. Otherwise Ford would have increased the flow, added fluid capacity and a larger cooler themselves instead of throwing the whole thing in the trash where it belonged. [/QUOTE]
