Outer Limits 4x4 Board

I have a 40 series cruiser with a Holden 253 and a 5 speed box. It wont go into 5th (just grinds). The box looks the same as a mates Bundera, it looks like a steel 4 speed box with a 5th gear section added in before the transfer case. I'm wondering if this is a popular conversion? Are there many reco'd 5 speed boxes getting around? Any light would be appreciated

The 5 speed H55F gearbox is the same as the 4 speed H41, just with the extra section on the back that contains 5th gear. You can either rebuild it, exchange for another unit or even buy a new one from Toyota, but that = $$$$$. Keep in mind that if the gearbox is from a 40 series originally, the top plate is different to the ones found in 60 and 75 series 'Cruisers. Ergo, the gearstick ops out of the floor in a different spot.

and if it is a "bj" box, i.e one from behind a 4 cyl diesel, the input shaft is different to those behind any of the petrol landcruisers.

arnt the bj hj and fj imput shafts the same and the hz box shaft is different

it will be different to the bundy gear box as well

Input shafts are a different length on the 'B' series motors, 2H, 2F, 3F and 1-2HT are common to each other, the 1HZ input shaft has a different spline count again.

..and if it looks the same as a Bundera transmission, its not H55F..
