Synchronized Transmission
GR1200
Got a big power REAL H-Pattern street car and need a built T56 Magnum? Look no further, the GR1200 is what you need. This is the strongest, smothest operating, synchonized street car transmission. No need for an external electric pump that is loud, annoying, and will die eventually.
The GR1200 (previously GR1000) now features a mechanical/internal oil pump, reduced gear noise, REM polished gearset, polymer fork pads and carbon/hybrid blocker rings for smooth shifting. Available for ALL Tremec Magnums, including the Magnum, Magnum-F, and Magnum XL.
We keep the TUET16362 Magnum-F GR1200 IN STOCK, all other part numbers and models are special order and custom built, with lead times around 6 weeks.
GR1200 Standard Options:
- Internal/mechanical fluid pump - no need for loud external electric pumps that can burn up
- Reduced Gear Noise (At least 6db lower gear noise)
- REM ISF Finished Gears, Shafts and Rails (increases gear life, less heat, less power loss, less vibration)
- Updated 2nd Gear Design
- Updated 1-2 Synchronizer Hub Design
- New Full Carbon Blocker Ring Set 1st and 2nd Position
- New Carbon / Hybrid Blocker Ring Set 3rd, 4th, 5th, 6th & Reverse Position
- Aerospace Polymer Fork Pads
- Grannas "Orange Man Bad" Cerakote (dissipates heat vs powdercoating)
- Built and Blueprinted by a Master Tremec Tech
- Dyno Checked for proper functionality before shipping
We can also do other custom options, like change gear ratios (5-6 only) or put GM inputs into Ford Magnum XL's. The GM swapped XL is common on Nissan applications or other applications where a lengthy transmission is required but also needs a small pilot GM input.
