i swear to god i think the t45 is on of the best trannies put into GT's in a long *** time. i LOVE mine, ive missed gears, beat on ir daily, power shift occasionally, with 80 k on it and it hasnt made a peep. 3650's are stronger on paper and mechanically YES, but they are super freaking unreliable and are a total hit and miss, i hate them.

 

Methinks rebel's right that the 3650 is technically a little stronger as far as what it's rated to carry, but from experience I've seen T45's hold up to abuse better than the 3650's have.. That's just me though.. But I'll second the motion that the 3650 definitely will not hold up under the kind of power you'd need to break 11's.. At least not for very long anyway..

 

i see you hitting a 12.7 and DR's with your current set up if you can drive. so maybe if you do suspention and a vortech or paxton or soemthing (because all you will do with a KB is spin) you might be able to see 11's...hell idk

 

Yeah I think my car is able with DR's to hit high 12's right now, problem is I'm not. Gotta mos def get use to the 410's. I've read and the past that 1st gear is useless when you get on her real hard and now I see. Gonna get with a friend of mine this weekend and post some flybys so you guys can tell me what I'm doing wrong...
