has anyone swaped out their 5spd for a 6spd. Are their any gains. My gt is currently stock. i am thinking about 4:10 or 3:73 gears and a 6spd trans.

there's a kit you can get for it, only thing is that the 6speed is a bit heavier than the stock 5speed.

I don't see a benefit for it either especially being most of them have 2 OD gears. Now If you can get your hands on the one from a 2011 that has 5 UD gears and 1 OD then maybe.

ya... a 6th gear...


if you mean hp gains? then no. if you mean tq gains? then no... the only thing you could really raise is your top speed, which wouldnt make a difference because if you are stock, then you have the stock speed limiter which is 115 for a V6 and 145 for the GT.

what i am trying to accomplish is getting the highway rpms down with the trans, but also add some low end power with the gear change.

you mentioned a kit for my upgrade. where could i find that?

It's usually done to handle more power. Keep in mind you will lose some 1st gearing due to the 6060 having a 2.97 first vs 3.27 for a stock 3650 so lower gears will be a must to keep the same acceleration. To get the same first gear accelration you would need 3.90 rear gears vs 3.55 stock. Second is 1.78 vs 2.00 stock. Third is 1.30 vs 1.32.

You will need a kit for about $4k plus a 26 spline clutch assembley. Or you can piece it together. 6060 trans, gt500 xmember, driveshaft, shifter and pins, boot, seal plate, 26 spline clutch, slave cylinder.

salve cylinder should be the same for all 3 trans, also i used d&d performance for my kit, they supplied me with just about everything i needed, though since i am a v 6 i had to shop around to a few more places for some other parts i needed. since u have a gt u can get everything but the clutch and gears from them. i put in 4.10 gears when i did the swap, but if i had to do it all over again i would use 3.73's
