Finally, Yukon Gears, got it back yesterday, have been working through break in now but can say it's worth it.
I can no throttle clutch crawl through drive thru now lol
Here's actual rpm data in both km/h and mph for Jeepers on both sides of the border.
My goal was 24-2500 rpm in 6th at 120 km/h (75 mph) and it does 2500 now. Goal achieved. I was driving essentially a 4-speed manual with the 3.73's and it was only happy on the street. Now i have fully useable 6-speed with no extra fluff at the top end, i don't want to do more than 75 mph in this thing.
3500 RPM Shifts
1st into 2nd = 25 km/h (16 mph)
2nd into 3rd = 47 km/h (29 mph)
3rd into 4th = 82 km/h (51 mph)
Note: with 3.73's and 35's...this 4.88's and 37's is now exactly 500 rpm higher for the same speeds.
Lastly, my Captain America dash light is coming on and saying the start/stop system needs service, even though i changed the tazer setting to 4.88's when i left the shop. Comes on after each start and get to about 40 km/h. Will have to dig into this, surely it's a simple fix. I have it disabled in the tazer settings so unsure whats up.
