I'm thinking of purchasing a W series Gearbox, well really i have just about brought a W55, but is there much difference between the W55 and the W57? strength, size, Build quality.

 

it will be going on the back o my 4AGZE (GTE).

 

any help will be much appreciated

the interwebz alrady has the infos

Awesome thanks mate.

some people say that the W56 and w56 are weaker than the w57 and w58, I've never seen any physical evidence of this. the main difference is the first three gears. In austrailia the w55/56 is primarily a commercial box(in hilux) and has shorter gears in 1st, 2nd and 3rd.

Basically the W57/58's are a closer ratio box than the w55/56.

 

physical differences are shifter positioning, though that's more depending on what vehicle the gearbox came from.
