Dont confuse it with a 1HZ gearbox which also has 21 spilines but longer.
You can also use any H55f that was mated to a 3B.
Most of the aussie 13BT had a H55f but most of the Japanese models were auto.
The H55f is still in production for some markets but for other engines.

Does the H55f have a marking or die stamp on it anywhere that designates it as an H55F and even better the spline count?

If not how can you tell other than just counting the splines?
