I have list of Trimatic auto transmission for 4 cylinder Toranas, but with two exceptions. I assume the HB Torana used a Borg Warner or similar and I can't find any model listing for the TA Torana. I assume the TA is the same as the LJ series and would have used a Trimatic "HL" for the 1300 engine and a Trimatic ""HY" for the 1760 engine.
I assume the rebuild costs for Trimatic transmission are similar regardless of the model.
