Unfortunately, that 2005-up T-5 is a unique animal. Yes, gears from a T5Z or even the Astro A-5 gears and G-Force Street gears will go inside, BUT if it will be bolted to the original V-6 bell housing there is NO INPUT SHAFT made that is the correct length that goes with those gears. Also, the front retainer on that configuration has a smaller outside diameter and will not center the transmission in a Fox (traditional Ford T5) bell housing. That front retainer matches the GM size centering hole in the bell housing... Next, I want to comment on the statement that gears for the 93 COBRA are available from Ford Racing. No, I am confident that Tremec has discontinued ALL of the T5 gears except for the 2.95 ratio T5Z that is still being sold as a new aftermarket transmission. Replacement Tremec 2.95 T5Z gears exist, but Tremec is very reluctant to sell them and when they do the price is sky high. This is intentional so that people will not buy the new gears as parts and build the T5Z transmissions rather than purchasing a complete new transmission. Now, to clarify about the 93 COBRA gears. Yes, the 93 COBRA T5 is made like the T5Z with the special caged, tapered bearing between the input shaft and the main shaft. Yes, the T5Z is a direct bolt-in swap for the 93 COBRA T5, but NONE of the gears are the same and that even includes the speedometer gear. Also, the COBRA T5 has the reverse brake feature that began with all Ford T5 transmissions in 1992, but the T5Z to this day still does not have that feature. There are well-respected online sellers of the T5Z that incorrectly advertise the T5Z as BEING the 93 COBRA T5. 1993 GT & COBRA T5: 3.35 1.99 1.33 1.0 and 0.68, 8-tooth Speedo Gear Book-rating is 300 foot pounds of torque. T5Z T5: 2.95 1.94 1.34 1.0 and 0.63, 7-tooth Speedo Gear Book rating is 330 foot-pounds of torque. Stan
