A Jacoby Transfer shows 5+ cards in the major. 1NT-2
or 2NT-3 shows 5+ hearts and could be 0 points. 1NT-2
or 2NT-3 shows 5+ spades and 0+ points. I would remove 1NT (via a transfer) to 2 with:
763 108764 7654 
2.
In this article, I recommend always transferring with a 5-card major.
After you transfer, a new suit bid is natural (4+ cards) and forcing to Game. If you transfer and then bid notrump, you are usually balanced (5-3-3-2) and offering partner a choice. 1NT-2-2-2NT offers him a choice of 4 contracts (2NT, 3, 3NT or 4). If you transfer to 2 and raise to 3, it is invitational to game with 6+ trumps (1NT-2-2-3).
What about Texas? 1NT-4 shows 6+ and opener must (100%) bid 4. Similarly, 1NT-4 shows 6+ spades. These bids are usually used to sign-off in game.
That means that 1NT-2-2-4 should have a special meaning. It can't be a pure signoff, because responder would have used Texas. So, this is a slam invitation (usually with no shortness). With shortness, you can transfer and then Splinter (1NT-2-2-4 -- to show 6+, 0-1 and slam interest).
Jacoby followed by 4NT should be Quantitative (invitational, typically 5-3-3-2). Texas followed by 4NT should be RKC.
