I had a Car and Driver article for the 1994 model year GMC Sonoma SLS ( a mechanical clone of the Chevy S-10 Super Sport, regular cab, with 4.3-liter V-6, 195-bhp @ 4500 rpm, 5500 rpm redline, and GM 4L60-E, 4-speed overdrive automatic trans, with 3.42:1 ring & pinion, P 215/ 65 HR-15 tires.
--------------------------------------------------------------------------------------* In 4th-gear, the truck is geared for 140.4-mph @ rated power.
* 2,500-rpm, in 4th = 78-mph.
* The truck achieves a governed top speed of 112-mph, in 3rd-gear, @ 5150-rpm.
* In 4th-gear, the truck holds 112-mph, @ 3,600- rpm ( 80% of rated power, and peak torque.
* 4th-gear = 31.2-mph / 1,000 rpm @ engine.
--------------------------------------------------------------------------------------
* Both a Borg-Warner T5 manual five-speed overdrive transmission, and New Venture Gear manual five-speed were available, depending on engine package.
I don't have any data for the NVG transmission.

As of 1975, Borg-Warner had engineered a 5-speed 1:1 output shaft unit, which would be used in conjunction with a lower numerical ring-and pinion to achieve the desired 'overdrive' final drive ratio, but without the 2% attendant mechanical loss of a typical OD transmission. Not used by GM as of 2004, when the S-10 went out of production.
