        4 1995 GT - Steven Installation Time: Less than 1 Hour

        Tremec TKO 5 speed

        The transmission is great, easy install, few to no problems. The only issue is that it sounds like gravel when you shift into 4th and 5th gear. Otherwise it runs great and shifts easy!

        This was the best mod ever, shifts are shorter and gears will hold the rpm .

        5 1990 GT - Joeycbr600

        Amazing !!!!!!!

        Well what can I say there's nothing like a brand-new transmission Out the box .. If you're running a car with a lot of HP and torque especially a Mustang with a T5 .. You know chances are your T-5 not going to last long . I must say this transmission has a totally different feel it drives a lot smoother than a T5 in my opinion .. Overall it's very much worth it It does not pay the purchase another T5 spend the extra get the bell housing and new clutch crossmember and transmission .. Also remember to use GM synchromesh transmission fluid ..

        5 Pre-79 Other - Frankb Installation Time: Afternoon

        Purchased for Cobra Roadster Project

        The transmission was installed on the engine before being installed into the chassis as a unit. Prior to installation, the tail shaft housing mounting lug was removed for cross-member clearance. The transmission was well packaged and palletized for protection during shipment and arrived without damage.

        Awesome transmission

        Love this transmission. Only had it installed a couple but I'm already in love. Still got awhile before she's fully broken in. I read some reviews before saying the Tremec TKO 600 was a little rough on shifts. Especially during break in. So far mine has been butter all the way up to 5th. I don't know enough words to describe how great it is. Point is, I love the transmission and recommend it for anyone wanting a great street transmission. If you have the money for all of the required upgrades. Then it's definitely worth it.

      Which transmission would be a better choice the .68 or the . 82? I'm running a 3.73's in the rear end.

      • When choosing the best Ford Performance Tremec TKO 600 Extra HD 5-Speed Transmission for your vehicle, the difference will be in the 5th gear or overdrive gear. the .82 will offer better acceleration in 5th, the .68 will offer decreased RPM's and fuel consumption in fifth gear.

      Hello, I am installing this into a 1994 Mustang Cobra. Does American Muscle sell a driveshaft that will complete this install for me with my application? Thanks in advance, Zach

      • We do not sell a driveshaft that would bolt on to this setup.
