with 4.10s in either tranny you will still get about the same milage as a stock GT (-1-3 mpg)

btw you will need a limited slip as well, i would recomend the detroit true trac as it doesnt use clutches

not just gt's but its the other way around. 3.55 in manual, 3.31 in auto.

Is the True Trac better then t-lok? It's like $200 more then t-lok lol is there any better of an advantage with it?

mustangman02232

yes, they dont have clutches that will wear out like the t-lok, it is a preformance part, unlike the t-lok which is a factory replacement part

Are you sure that it was the other way around? I thought when I read it (wherever I read it) it made sense to me because I thought of it as the 3.55 was making up for the fact that it was an auto and would automatically loose some on acceleration? Not saying that your wrong or anything, its just usually if I can associate it to something and it makes sense to me I remember it pretty well. It just seems like I was pretty sure about this.

good choice IMO, that is what I would pick

the deal with auto is that its hard on gas as it is compared to a manual.. so they put the smaller gearing in..

ill ook up the rear end ratios for the all 4 cars

thats gay.. inford doesnt have the info...

any 5 speed GT until 07 has 3.55s whjich are now optional, all the rest are 3.31s, if you mean tranny ratios, the t-3650 is .68, the t-5 is .72 and the auto (whatever it is) is .75
