Trans Gears

I'm looking for an upgrade for my 3.4s T-5. Now, I'm looking to push her up to around 300+ft/lb torque so I was thinking about using a 3rd gen T-5 and getting G-Force gears but that amount I could get TKO to fit. Anybody know of any decent gears for T-5s?

Yea, the only semi-reliable upgrade for a T5 is G-Force internals, but I'm with Matt.....go straight to a TKO trans.

You do not have enough torque to break a stock t-5, why worry about upgrading?

well I'm hoping to be around 300ft/lbs BUT the T-5 used on the mustang and 3rd gen is stronger than the 4th gen T-5..mines rated for 230ft/lb so i was thinking about using the 3rd gen T-5 or a G-force gear kit cause I REALLY want to keep that 3.75:1 1st gear

D&D makes good stuff from what I've heard. How wide are the ratios in your trans?

Well, FWIW I don't think such a wide ratio gearset is good for torque handling or keeping your engine in the power band.

Yea but if i put a T-56 in it that would be like starting in 2nd gear...not to mention the T-56 would require a special bell housing I'd have to have custom made.

WildbillyT...my 1st gear it VERY short but it helps the car to get rolling once I'm in 2nd she pulls pretty good(for a v6) all the way up to 4th and if 'm already going fast enough 5th ain't terrible either

a 3.75 first gear is useless if youre pushing enoguh power to break a t5...tirespin.

read my post again....if youre pushing enough power to break it

i doubt youll break a t5 with a 3.4 unless you have slicks and dump it at 5k rpm

key word...shouldnt

stock t5s are kinda a crapshoot....some hold up for a while, some break right away....kinda like a 10 bolt, or stock foxbody rear axles...some go 11s on them, some break them in the 13s
