Volvo iShift transmission

I liked the new one I drove a while back. I used the manual switch, shifted most times at my choice. Check this: I drove a new 670 with the D-13 Volvo engine and the I-shift tranny. After a couple of months, I did 10K miles with the thing set on auto-shift, then another 10K with me and the manual shift configuration....I got 6.8mph on that rig, while the computer/autoshift did 6.3mpg on comparable driving conditions. I don't really like auto trannys, but I thought the I-shift was a good unit for all that it thought it could do better 'n me.

 

Best automated transmission available anywhere.
There is nothing that comes close.
Durable , reliable and not temperamental like some of the others.
Seen them used at over 400 000lbs.

 

and expencive to fix if fails

 

1 day in LA traffic convinced me the I-shift is better than manual. Oh, and mine gets 8.5mpg average if I keep it around 65 and dont hammer it.

 

It is a really good AMT. The only issue I have with any of them is sliding 5th wheel. It is truly and art form to learn how to slide a 5th with an AMT.

 

to slide use manual mode, 1st ore RL gears. with minimal throutle truck slowly moves.

 

Fifth wheel trick. Drop the trailer, release the fifth wheel, hop on the rails and just grab the plate and move it. Saw a guy do that in the rail yard and he got it exactly where he needed it on the first try.

I am on day six of a 2012 vnl760 with Ishift 12 speed tranny. I run Chicago intermodal and have hit some stop and go traffic a few times. I am loving it so far.

When you are in slow traffic, idle speed, you can take your foot off the throttle and use the +/- gear buttons on the gear stalk to speed up or slow down.

I have not used full manual mode yet. But mine has economy mode and performance mode. Performance revs higher and hits most every gear. Economy shifts quite early.

When I am bobtailing it chooses to start in fourth gear.

I agree it is the best right now
