CVT Gear Ratio/Final Drive Ration question...
ATTN: GRAMPS....maybe you have some insight to this...of course everyones knowledge is welcome.
But Gramps...I finally did some homework on the CVT2/CVT2L gear ratio/final drive ratios you've mentioned on here before, and finally made some sense of it all. As you've pointed out....both tranny's have the same gear ratio range as each other....2.349:1 to .394:1. But the difference in the Off Road Patriot is the Final Drive Ratio (transaxle?) of 8.135:1 on the Off Road version, vs. 6.12:1 on the normal 4x4. So this then, does explain why my Patriot runs at 3200 RPM at 75 mph, when everybody elses would run at about 2400 rpm at the same speed.
(side note: Jeep should not advertise the CVT2L as a different transmission with a separate lockable low ratio, when all it actually does is lock the same CVT into it's lowest range...2.349:1 x 8.135:1 = 19.11:1...it's very deceiving, because it changes ALL available gear ratios, not just the low one).
Anyway the point of this all...a question... Is it possible to change the final drive gears to match the normal 4x4 ratio of 6.12:1....on a Off Road Patriot? I don't have much of a 4x4 truck background and not sure what this would entail, but it seems like real truck guys do this all the time on Wranglers/Full Size pickups or whatever. It seems that if all the software and shift lever controls are computerized or internal to the transmission, then what effect, if any, would new final drive gears have?
I'm thinking along the lines of how off roaders install Dana 44/60 axles or whatever, which I think changes the ratio with it? So could one do a similar swap on a Patriot? :crosses fingers:
