will this transmission be good for my stock 4.6 My automatic transmission in slipping, so I'm thinking of upgrading to thistransmission, but not sure if it would be a good idea since my mustang is dead stock?

Stangstang1 Year: 2003 Model: GT

  • Bad idea. This transmission is geared for high horsepower cars, they will be able to overcome the tall ratios that this trans contains. Your car will struggle to accelerate in stock form unless your rear differential ratio is changed. A Tremec 3650 would be more suitable for your application.

What is the "lowest" gear ratio you would recommend for this to be efficient? What read gear ration would you recommend for best performance and drivability?

kevinrocksman Year: 2002 Model: GT

  • With a transmission like this one it really doesn't even matter to be honest. Unless you are going custom this is the best transmission for any Mustang. I would prefer a longer ratio. The 6th gear is used only as an overdrive.

Short Shifter included? Wondering if this transmission includes a short shifter and if so what brand, and if not, which short shifter would be the proper fitment?

mromero94 Year: 2002 Model: GT

  • Yes it does have a short shifter. Almost all high performance tremec Manuel transmissions come with short shifters from the factory

    Love Tremec transmissions

    This is a great transmission. I love the way this thing shifts and its super easy to drive. I have not had a 6 speed before and was a little concerned about getting into 5th but after driving I have no worries. If you buy one of these make sure you can source a clutch fork if going on a cobra.
