Best trick is one from Power British... which is viewable at:

Or for convenience (and I hope Brian doesn't mind) I'll the content here:


"TR-4 Through TR-6 Transmission Installation
"While removing the transmission from these mid-year triumphs couldn't be
easier thanks to the separate gearbox cover, reinstalling the transmission
can sometimes be quite difficult, especially if it is equipped with an
overdrive unit. Supporting the weight of the transmission while aligning the
input shaft splines with the clutch disk can be a tiresome task, even with a
helper.

"Try this tip: From your local hardware store, purchase two 5/16" x 24 UNF
bolts about 3 1/2" - 4" long. Remove the outer two mounting studs from the
top rear of the engine block. Cut off the heads of the bolts and round over
the ends with a file. Install the longer bolts in place of the studs. Now
you can slip the transmission onto the longer pins and align the input shaft
while the pins support the weight of the front of the transmission. Once the
transmission is mated up to the block, install all of the bolts, then remove
the longer pins and reinstall the original studs. Simple!"

It is quick and easy... and the dowels you end up making, take most of the
load.  I've used this method numerous times, and each time have just been
able to slide the gearbox right up to mate with the engine block, no hangs
ups at all on the disc splines.  If you do however have the splines still
not wanting to cooperate with their matched partners on the clutch disc,
just remember to rotate the tailshaft a few degrees each way (in fourth
gear, well you don't have to, but then it is a 1:1 to turn)... and you
should be able to line up the input shaft  splines with that on the clutch
disc and you should feel the gearbox move forward easily.

Kai (who won't be doing that procedure anymore for a long long long long
time!)
