The Borg Warner / Tremec T56 is a stout 6 speed manual - damn good looking too! Transmission below is pictured with the LT1 style bellhousing, which bolts right up to any small or big block Chevy engine.

This is the original equipment transmission for fourth generation Chevrolet Camaros and Pontiac Firebirds, fifth generation Corvettes, and Dodge Vipers. There are three versions, each with different gearing and torque capacities, as outlined below.

Gear A B C 4L60E
1 2.66 2.97 3.36 3.08
2 1.78 2.07 2.07 1.62
3 1.30 1.43 1.35 1.00
4 1.00 1.00 1.00 0.70
5 0.74 0.80 0.80 N/A
6 0.50 0.62 0.62 N/A
Reverse 2.9 3.28 3.28 2.29
Torque Capacity (lb/ft) 450 400 350 350

Due to its higher torque capacity and better gear ratios, we recommend A, which can be found in '94 - '97 Camaros and Firebirds. When the LS1 was introduced in '98, the T56 received a different bellhousing and input shaft which is not directly compatible with the LT1 in the Impala.
