Thanks. All quite correct. However, this is in the transmission it self.
But, I see the point, at last!!!
Lower gear ratio in the rear differential effects engine rpm at any given MPH. That effects the transmission shift point. Early shift! 3.31 to 1 as an example
And, a high ratio causes a later shift as to MPH. 2.88’s as in many XJ’s. Mine included.
I did not mess with the 4l60E, a close cousin to the 700r. The LT1 torque pulls those tall gears, event with the .70 OD with alacrity.
Now, some say the 4.2 and 2.88 can’t pull a 700 because of the high OD. others say, no, it does well.
OTH, the torquey 4.2 in my 94 Jeep pulls OD well. No where near as spy as the LT1, but quite decent…
- of course, at speed, it’s body is a “brick” compared to the SIII.
Different cars are driven differently…
No snow around here, but the Jeep in 4WD and on true M&S tires could go where the Jag dared not…
