Description

An MWR exclusive
Very low mile (under 50k) used 6-speed 4.3:1 transmission, specially adapted by MWR to bolt right in to 2000-05 MR2 Spyder (manual). Inspected for condition and function by MWR and includes 30-day warranty if bolted to unmodified naturally aspirated engine.

This is a very special transmission
It will bolt right up to any 1ZZ or 2ZZ engine. Shifter shaft and reverse blockout are included and installed. 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.

Gear selection
Axle ratio is 4.312:1, so it is a very usable transmission for street driving or racing and it works best with forced induction. Revs are lower on the highway than they would be with a US market 4.5:1 Lotus/Celica transmission (~3400 rather than 4000 (Lotus) or 3600 (Celica) at 80mph) so fuel economy is noticeably better.

Quality and strength
Built with 100% 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.
