$2029.98 Classic Mini Cooper late model Rod Change 4 synchro Gearbox with 3.1 final drive

Rebuilt gearbox. The 'rod change' gearbox was the final and arguably the best design and can be adapted to any Classic Mini. These were factory installed in most Minis manufactured after January 1973.  We rebuild these late model gearboxes with the best available components from our vast inventory of disassembled units. New bearings, synchros, gaskets and seals are installed & this version is set up with the 3.44 final drive differential, probably the most versatile ratio for the way the Mini was intended to be driven!

We also offer a complete kit that adapts this design to replace the standard 'remote style' or early 'magic wand' transmission if you are upgrading to a bigger engine  (see part number MMKT0803).

Please note!  VERIFY your idler bearing size!  Thse late model cases have the LARGE A+ idler gears!

I need to know exactly the weight of this gearbox.
On the scale the complete Rod Change gearbox weighs in at 57lbs

How do I know which transmission my Classic Mini has?
Created: January 20, 2014
It’s really quite easy to tell which generation of gearbox, shift linkage, and axles your Mini has. Let’s say you want to order a replacement but terms like “remote”, “rod-change”, or “pot-joints” have you a little befuddled about just what the heck to order! Let’s very simply describe the three styles of transmissions and axles used in the production of the Classic Mini.

ENGINE TRANSPLANTS - gearbox information
Created: November 01, 2000
Selecting the right final drive ration is a subject worthy of an entire book to explain the whys and wherefores, and also causes much consternation on the part of the transplanter. Much confusion’s spread over which gearbox has the best ratios, is best to use, and with which FD. For a detailed account on this and covering all gearboxes fitted as standard to the Mini, see the relevant separate articles 'Gearbox - Standard production gearbox types'.

The final drive gears are ultimately responsible for the way your Mini goes after engine, gearbox, and under carriage tweaking has been applied. The aforementioned and the degree to which it has been done will affect the decision as to what Final Drive is required. They’re also responsible for much discussion between many tuning freaks, and confusion to the less informed.
