Flying Pig Posted 1 hour ago Share Posted 1 hour ago My current customer seems to be having a slow year coming on. In the past when I had an opening, I’d haul precast to job sites. Some of them can be a little spongy. My current truck(Ford LTA9000, Cat400, RTXF 14609B, 3.58 rears, lo24.5) has somehow eaten its coolant so between the two I need to explore other options. I may be getting into more of the doggy job sites. im looking for transmission options with lower ratio gears suited to the high torque needed to pull a load without breaking or bending driveshafts and axles. My current low gear is 14.something to one. I’d like to get lower than that. Can anyone show a chart that shows the different ratios? It’s hard to spec a used truck and expensive to modify. So far on my hunt I’ve not come across any with 2 speed axles. Like to stay with triple countershaft trans and older, non computerized trucks. Also, overdrive for highway miles would be good.

Geoff Weeks Posted 1 hour ago Share Posted 1 hour ago Eaton and Spicer (TTC) are twin countershaft transmission not triple. IFAIK Mack was the only one to use triple. You're unlikely to find a 2 spd in a used truck now, but any Eaton 402 equipped truck housings can accept a Eaton 2 spd center section. Eaton or Spicer/TTC 18's have lower ratios in the bottom end while still having O/D's on the top. Problem is with the deep reduction on the bottom, the driveline has to take all that torque.
