[TR] We rebuilt two tr trans today

[Chris Simo]

My car Club got together for a tech session today.  We rebuilt a tr6 and my
tr4 gearbox. What a pain to remove the needle bearings on the tr4!

Both were od and the od's were working well, so we did not work on the back
ends.

No special tools, but used heat gun often on the gear case. Hf seal install
set for seals and needle bearings.

Was much easier than I thought.
