Freedomline transmission

Parts and service availability is always at the top of my list in purchase decisions. If I can't easily and consistently get parts I probably won't own it. This has worked for me with trucks, tractors. construction equipment, forestry equipment.

 

I would look for a Volvo with a Cummins Engine if you are set on the Volvo 670. You will get better performance and better mpg with the Cummins versus the Volvo engine.

ZF 12 st and I-shift share many parts, like clutch parts, actuators, electronic board....

Mechanically transmissions are different but made in the same style and I cant say what tranny is better!

 

if you can buy i-shift it is far better hardware than AS tronic

you can drive volvo ishift like it is a racecar , it performs very smooth shifts and it is fastest gearbox on market

 

I use to work on both and yep, mechanics say volvo box is better, but as I can see there is no notisable difference for driver.

 

it is far better mechanically

volvo ishift can be speced up to 200-250tons

i have never seen astronic (12) above 90t and most of them are up to 70t

 

there are three ore four different i-shift boxes of different torque rating.

 

i know but still this is far behind astronic
