Hi, I am a new member on the forum.
I am in the process of having my 1998 Hilux pick-up's engine replaced with a 3UZ-FE. I would like to know which gearbox will be best to fit, 5 or 6 speed and what should the correct ratio of the diff be? The current diff ratio is 4.875. Thanks

3uz-fe should have its stock ecu, stock loom and stock a/t
different a/t will not work
the 650 is considered more reliable but also consider aging

correct diff for 5spd a/t is ~3.3 and 3.6 for 6a/t
truck will require slightly higher diff ratio to compensate weight and wheel size
