  We investigate the production and the decays of pseudo-Goldstone bosons
(PGBs) predicted by technicolor theories with the GIM mechanism (TC-GIM). The
TC-GIM models contain exotic fermion families that do not interact under weak
$SU(2)$, but they do have color and hypercharge interactions. These fermions
form PGBs, which are the lightest exotic particles in the TC-GIM models. The
spectrum of PGBs consists of color octets, leptoquarks and neutral particles.
The masses of leptoquarks and color octets depend on a free parameter - the
scale of confining interactions. Characteristic for TC-GIM models is a very
light (approx 1 GeV) neutral particle with anomalous couplings to gauge boson
pairs. We show how current experiments constrain the free parameters of the
models. The best tests are provided by the pp --> TT and e^+e^- --> P^0 gamma
reactions. Experiments at LHC and NLC can find PGBs of TC-GIM models in a wide
range of parameter space. However, TC-GIM models can be distinguished from
other TC models only if several PGBs are discovered.
