Gear Ratio/Torque Converter?

Nicostang02 · Jul 14, 2005

I have a 2002 Mustang Gt i was wondering what is the stock gear ratio for the differential, and also i would like to know what is the stock torque converter stall rpm?

3.27:1 for stock I believe

The stock converter is rated to stall from approx 2300-2700. Each car will vary a bit due to the actual tq output of the engine.

Johnny's got it:

From my 02 Shop Manual, the 4R70W with a 4.6 is rated to stall between 2339 and 2738RPM.

Back when I was only making 212rwhp/282 ft-lbs-mine would stall at just over 2400. It was good enough for a 1.92 60' in my lead-sled of a car.

that is not bad for a stock converter.. 2400 is below the peak tourqe of a 4.6 but still better off than the old 5.0's were stock with a auto.. or the stock LS-1 camaros with a auto/
