What transmission is in a 1991 S 10 4x4?

The 1991 Chevrolet S10 4x4 pickup truck was equipped with a manual transmission as the standard option. Specifically, the S10 4x4 models from that year came with a 5-speed manual transmission.


Detailed Overview of the S10 4x4 Transmission


The 1991 Chevrolet S10 4x4 was available with two transmission options - a 5-speed manual or a 4-speed automatic. The standard transmission was a 5-speed manual, which provided the driver with more control and better fuel efficiency compared to the optional automatic.


The 5-speed manual transmission in the 1991 S10 4x4 was a Borg-Warner T5 unit. This transmission was commonly used in various GM vehicles of that era, including the S10 pickup. The T5 was a rugged, reliable transmission that could handle the demands of off-road driving in the 4x4 S10 model.


Some key features of the T5 manual transmission in the 1991 S10 4x4 include:



  • 5 forward gears plus reverse

  • Gear ratios optimized for both on-road and off-road driving

  • Robust design to withstand the increased torque and power demands of the 4x4 system

  • Hydraulic clutch actuation for smooth, easy gear changes


The 4-speed automatic transmission option, while less common, was also available for the 1991 S10 4x4. This automatic transmission provided a more convenient driving experience, especially in stop-and-go traffic, but sacrificed some of the manual's fuel efficiency and off-road capability.

How can I tell what T5 transmission I have?


Front Countershaft Bearing Race
A quick glance at the bearing race that sticks through the face of the transmission main case will reveal if the T-5 is a World Class or not. While the word "Timken" only appears on a World Class bearing race, not all of these races have the Timken label visible from the front.



What does the S stand for in the transmission?


sport
"S" is for sport. If you're driving on twisty country roads and want to keep the RPM up as you wind through corners, the "S" position is where you want to be. In "S", the transmission holds lower gears longer for more power as you come out of the curves.
