Tremec T56 Magnum 6-speed Transmission for GM LS


Vorshlag sells the Tremec T56 Magnum for use with a number of our GM LS swap kits - this is the unit we design around primarily now, as it is brand new, rated for 700 ft-lbs of torque, and comes in two ratio options. 

The kingpin of TREMEC's high performance line-up, the T-56 Magnum double-overdrive 6-speed transmission takes the very best from TREMEC's current OEM technologies and pairs it with the most popular features of the TKO 5-speed.

Able to withstand a massive 700 lb-ft. of torque while providing unbelievably crisp shifts, no other manual transmission on the planet offers as much combined strength, versatility, and general ease-of-use as the T-56 Magnum.

Known in its original equipment form as the 'TR-6060', the T56 Magnum is direct-shift aftermarket version of the same transmission found in many of the most celebrated factory super cars – including the C6 ZR1 Corvette and ACR Viper – giving you refinement where you want it and strength where it counts.

We installed a T56 Magnum in our first E36 LS Swap Track car with 500 whp

NOTE: The T56 Magnum is 1.5" shorter than the production 1998-2002 Camaro T56. This is a brand new "direct shift" transmission 6-speed based off the updated TR-6060 unit, which is much stronger than the original Camaro Borg-Warner T56 transmission. 

The T56 Magnum gives the perfect length to align with the stock shifter location, making it work well for for the the BMW E36, E46, and E36 RHD chassis and an accompanying Vorshlag LS V8 swap kit. This need very limited trimming of the shifter opening in the transmission tunnel. This transmission includes a Tremec shifter base (as shown in these pictures) but no shift handle or knob.

Shipping costs? Freight Shipping to a business address in the 48 contiguous United States is free, and shown in the options and explained in the notes below. Residential shipping is $100 extra. Call Vorshlag for more details.

 

The T56 Magnum XL comes in two different gearing options.  Choose the one that you feel is a appropriate for your build.

Tremec Magnum XL Gearing Options
================================================
 1st      2nd       3rd       4th      5th       6th

2.66     1.78     1.30     1.00     0.74     0.50          (Wide ratio)
2.97     2.10     1.46     1.00     0.80     0.63          (Close ratio)

 

We pick the "Wide" ratio box for street cars, as 5th and 6th gears allow for highway cruising with low RPMs and good gas mileage. The "Close" ratio box is better for dedicated track cars, as the 5th gear ratio is more suitable for use on a road course.

NOTES:

1. This T56 Magnum for GM use is usually in stock at our warehouse and can ship quickly.

2. The proper bellhousing for our V8 swap kit use is sold separately and shown in this same web store section.

3. This shipment is heavy enough that it must ship via freight truck - which adds $0 to a business address with fork lift service or $100.00 to residential address in the lower 48 United States (lift gate service). That prices are shown in the options. Call for more details or other shipping options.
