The part you are looking for, is called the TCU.

In the US, the VH41 was not sold until the 97 year. The VH45 was sold 90 through 96. I am not sure if the transmission was changed between the first and second generation. The second generation Q (Y33) was introduced in 1997.

I do know that the gearing is different from 90-93 and 94-95. The TCU changed in 1993, then again in 1994 I think.

In 1996, when the OBDII system was utilized, I bet the TCU changed as well.

The FSM goes into great detail on idagnostic and complete overhaul of the transmission.

Here is the pinout drawing:
