“Installed my new TREMEC Super Duty T5 Z Spec from Modern Driveline in my 90 Mustang GT. What a difference!
Car drives so much better with modified 1st and 5th gear ratios along with my 3.55 rear gears.
Wish I would have done this sooner.”

“Jas, Glad you love the new T-5z with the 2.95:1 first gear ratio. It’s a great match with the 3.55:1 axle ratio.
Thanks for making it Modern.”
