An MWR exclusive
Custom Monkeywrench Racing transmission built in-house using 100% brand new Toyota/TRD OEM parts.
This is a very special transmission
It will bolt right up to any 1ZZ or 2ZZ engine and is specially modified by MWR so that it may be installed in any 2003-08 Matrix, Vibe or Corolla. No adapters, other parts or or custom work of any kind are required for the installation. Works with stock or aftermarket clutches, flywheels, shifters, shifter cables, axles.
Performance and Value
You get a factory fresh 6-speed transmission; compare that to Toyota’s retail price of over $2450 with no options for gearing or fitment!
Axle ratio is 4.529:1, so it is the best choice for NA performance and for road racing applications where short, tightly spaced gearing is needed. Improves acceleration noticeably compared to stock 5-speed.
Quality and strength
Built with 100% new OEM parts so it is as strong as an OEM transmission. MWR recommends a maximum of 275whp for road course use and 350whp for street use though actual transmission durability will vary based on usage, vehicle weight, torque, clutch type and heat. If you will be exceeding those numbers you should definitely consider stronger solutions such as Jubu or Kaaz gear upgrades or MWR E153 swap for high power street or road course. Because of varying customer power levels and usages MWR guarantees only initial quality and function.
Final Drive: 4.529

If your MR2-S already has a 6-speed shifter installed, you may re-use it and save the cost of the assembled shaft. If you are converting from a 5-speed, you DO need the shifter shaft.
