Subaru Tri-hybrid FT4WD Transmission (centre locking differential) The idea behind this was the ability of having AWD while not losing the 4WD advantage. Aussie's won't know much about the FT4WD gearbox I am talking about and American's won't know much about the dual range (D/R) EJ gearbox either. But I will explain everything here. Just so you know, I spent 5 months reseaching this before I bought anything or even pulled apart anything for that matter. The idea spawned from wanting to do an EJ conversion which normally requires an adapter plate to adapt the engines bolt pattern to the gearboxes. Although if you use the EJ gearbox this isn't needed. But even with the ability to convert the low range in the D/R EJ box to the better EA82 gearing you still have AWD with a viscus centre diff which can allow you do get stuck with only 1 wheel out of traction. Where as 4WD locks the rear and front diffs together so you have to always be turning 2 wheels at a time. After the weeks of research I decided it was time to buy and find out for sure if the EJ D/R gearbox is really just the same gearbox as the old EA82 one only with a different engine mounting and a centre LSD. I bought my FT4WD (import only here in Australia) from Rising Sun in Adelaide for a very decent price. And I already had the full EJ22 Liberty (known as Legacy's else where) donor car with the D/R transmission. Plus I had a normal EA82 5sp with the 1.59 to 1 low gear set to go in the EJ casing. So I got stuck into ripping the gearboxes apart. This is a rough guide of the steps I took to pull the box down as much as I needed to: For putting a 1.59 to 1 low gear set in the EJ box (comes with 1.19 to 1 normally) you will need to change the whole shifter fork, gears, synchros, etc.. Heres how. The reason the EJ transmission has the detent and swtich is because the PT gearboxes have the low range lever connected on a bar to the back casing which holds the detent and swtich. This is so the 4WD lever is for both 4WD and low range. Where as the EJ AWD only needs a low range lever.
Sorry, not finshed yet!
