based on the T-4 and earlier SR4, and was sold as the BorgWarner T-5 until the design was sold to TTC (aka Tremec) in the late 1990s. The SR4 was a light-duty 4-speed manual that used ball and needle bearings on the countershaft with bronze synchronizer rings. The T4 improved this design with tapered roller bearings on the input and output shafts and a straight roller bearing on the counter gear. The T-5 is a T4 with an added overdrive gear. The T-5 carries a part number of 1352-000-''xxx'', where ''xxx'' is a three-digit application-specific number ranging from 001 to 260 that also can be used to distinguish World Class from Standard T-5 transmissions. The first T-5s were installed in the

Models

The T-5 is available in "World Class" (WC) and "Standard" (STD) models; STD are sometimes known as Non-World Class (NWC). Compared to the Standard, the WC changes bearing types and blocking ring materials. Externally, the tapered roller bearing race for the countershaft at the front of the WC, facing the clutch and below the input shaft, can be distinguished from the corresponding straight roller bearing cup of the STD. If this is not visually accessible, the color of the synchronizer rings can be used to distinguish the two types, with the oil fill plug removed. WC transmissions should be filled with
