T5 DOWNSHIFTING DRAMAS & FITMENT TO XB 351
New to the forum, I've started the rebuild on an XB GS coupe and I'll put up some photos soon. At the moment I'm sorting out my workshop and accumulating parts I'll need, and recently bought a T5 to fit behind a 351 in it (replacing the original 250 6 cyl & single rail). It came from an XH XR6 and was only $250 with all brackets etc (except gearstick) but it has trouble downshifting from 5th to 4th. It only occurs at that time, and it will find all gears, but when downshifting you have to find neutral and partly shift up to 3rd before selecting 4th.
The box came from a country town and the local mechanics could not solve it. Other than this problem the box is in good condition. Is this a simple fix or is it terminal???
Also I know the box isn't a straight bolt-in, anyone done this before?
