Check your engine number, and/or the numbers cast in your differential housing (just forward of the dipstick), and see where it fits in the following listings to get an idea of the serial number and year of your TEx.
If you check on the page showing the changes that were made during production, it may help to narrow it down even further.
(If you have a TEx and can supply me with the engine serial number, tractor serial number, and transmission date code, please send it to me so I can add it to the charts here.)
