Hello everyone...I need to pick some of you, gear heads, about a Daf Leyland T244 (military) conversion I intend to do...The t244 is hopelessly under geared for highway use, 2700 rpm for 50 mph...I want to swap the Turner (Spicer?) T5-350 5 spd transmission to something with the same low 1th gear (7:1 ratio) but with an overdrive or 6th speed to lower the engine RPM for highway use...Turner's 5th gear is a 1:1 ratio...I would love to put a ZF automatic transmission with the dry clutch...but it will be hard to sacrifice the crawling 1st gear manual advantage...any suggestion??
