There is not an Aptech supported GARCH threshold model procedure. The Time Series MT includes the Hansen threshold model, which could possibly be adapted to fit a GARCH model.
In addition, Philip Hans Franses and Fick vn Dijk's book "Nonlinear Time Series Models in Empirical Finance", is written using GAUSS for modeling and estimation. While I am not positive about the complete contents of the book, you may find a GARCH threshold model example with accompanying GAUSS code provided. Further information, including datasets and downloadable GAUSS codes are found at
