if you could get it to fit (pun), then i imagine you'd reap all the benefits. longer final drive gear, more torque in 3,4,5. higher mpgs....
^ the 6 speed
^the 5 speed


here's a the 6speed at various prices used, and in case you just need to replace the 5speed.

 

The driver's side drive axle may be another issue (length, splines, hub, etc) as the parts did change from GE to GK

 

 

Knope,

Adding some tech info to go with your trans drawings.

Just for reference on the ,"longer final drive." I think the big gripe among the GK guys was that Honda screwed up and didn't change the final drive ratio. They only tightened up a few ration in between.

 

 

There is a thread on here somewhere, and a person was talking about reaching out to a gear maker or trans builder type of place and seeing what it would take to get a real 6th gear


Additional topic:
I went from a 2015 6spd to the 2018 CVT, and I am convinced that the fake 7spd paddle shifters have the fake 3-6th gears set up to mimic the true 6mt cars, then when I hit 7th the rpms drop again, then when you knock it to drive and out of sport, the rpms drop yet again. Whatever the ratio the CVT is using to act like it has a 7th gear would make for an amazing 6th in a true manual car.

 

Would love a genuine, lower rev on the highway-sixth gear. Makes me wonder if MPG would hit the 50s.

We definitely would have to remember to downshift into fifth otherwise that thing won't go anywhere.

 

sometimes, in 6th gear...... I wonder if I accidentally put myself into 4th gear =\

 

Same here, I find myself often second-guessing that shift to 6th. A 7th gear, true "overdrive" gear for the highway would be nice, or in reality just a taller 6th gear. It feels like it needs it.

 

And the dif ratio? Would change everythig, even with no changes in gears ratio...

 

Well all this data makes me confident I don't need a 6MT swap.

We have the 6MT HR-V and the 6th still revs around 3K @ 115KMH. Just like all other 5 speeds. SMH.


WE WANT OVERDRIVE.
