MWR Toyota Transmission – Lotus/Celica 6-spd 3.9:1 LSD – Used



An MWR exclusive
Very low mile (under 50k) used 6-speed 3.9:1 transmission. 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 and is specially modified by MWR so that it may be installed in any 2000-05 Celica (GT or GTS) or any 2005-12 Elise/Exige with 1ZZ or 2ZZ engine. No adapters, other parts or or custom work of any kind are required for the installation. Includes shifter shaft and reverse blockout. Works with stock or aftermarket clutches, flywheels, shifters, shifter cables, axles.

Performance and Value
TRD’s trusted helical limited slip differential is already installed! Add up the cost of any other new or used 6-speed, LSD, LSD install and installation labor and you can see that this is a tremendous value. The difference in grip and handling balance can be amazing. No special LSD oil required.

Gear selection
Axle ratio is 3.941:1, so it is a very usable transmission for street driving and it works excellent with forced induction. Revs are considerably lower on the highway than they would be with a stock 6-speed transmission so fuel economy is noticeably better. Most people find that because of the car’s light weight there is little penalty in acceleration times with supercharged or turbocharged engines though it will slow down naturally aspirated cars a bit. There can actually be an acceleration advantage for forced induction cars because the lower gears are much more usable and less shifting is required.

Quality and strength
This transmission is as strong as your original 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. Includes 30-day warranty if bolted to unmodified naturally aspirated engine with normal street usage.
