t45 vs. t3650

00mustang92 · March 22nd, 2011, 08:27 PM

I have a 01 bullitt GT.. Its got the 3650 in it.. I broke the input shaft off my tranny... I can get a t45 which I heard is all around better besides the shift forks and you can have better one put in the for not a lot and they be about bulletproof with the power I'm putting down.. (362rwhp) Help me pick which is better.

Shaun03GT · March 22nd, 2011, 08:46 PM

T45 is not bulletproof. The only manual transmission thats pretty strong for our cars is a T56.

Your tranny is gone. Spend the money and get you a T56. Upgrade while you can.

F8L GT · March 22nd, 2011, 09:30 PM

or just buy a built 3650 for abour 2k

Serlin · March 22nd, 2011, 09:41 PM

Actually, I"m in the market as well...

asiansensation78 · March 22nd, 2011, 09:44 PM

T-45 has shift forks made of cheese and the TR-3650 uses synchros built from cardboard. Pick your medicine lol, but the 3650 is a bit better in a lot of ways and can be purchased for a good price.

stal94gt · March 22nd, 2011, 09:46 PM

t45 can handle higher rpm's. they both hold around the same power so in my opinion the t45 is better.

00mustang92 · March 22nd, 2011, 09:55 PM

thats a good site you found I like that... Am not looking to out 2k in it... Wish I could find a used tko or t56 but heard theres quite few mods you gotta do for them

i have a stock t-56 with a 26 spline input shaft, and tob sleave and that cost about 450 for that setup and its good to handle a lot of power, the weak spot in the cobra t56 is the 10 spline input shaft.

00mustang92 · March 22nd, 2011, 09:57 PM

the site thats linked on here said t3650 was made for max torque of 360 and t45 is 400... My car at max puts down bout 380

yeah, have you seen teh new 3650 that can hold either 750 or 1000+ hp? I will have to find it. saw it on tv from some auto show.

the t-45 is rated at 325ftlbs

T-45:
Shitty synchros
shitty shift forks
even shittier shifter selector arms
shitty input shaft

T-3650
shitty synchros
shitty inputshaft

So take your pic theres a reason ford switched to the 3650 over the t-45.

00mustang92 · March 23rd, 2011, 09:25 PM

I no I saw some where.... I can get a t45 with 75k miles bout same as my car has for $650.. Id love to have the t56 but the cost is to much for me... unless anyone knows someone with a used one for decent price...

ace87 · March 23rd, 2011, 11:20 PM

T45 FTW! they have less issues than 3650's and shift better (cold or hot) They also are not that hard to rebuild. Yes the shift forks are called "weak", but its a shifter not a prybar! shift good and you wont have to worry about bending them. For those who complain about synchros not lasting its probably because you were trying to force shifts to happen in the first place.
If you want to powershift or tear at the shifter, get yourself a sequential/dogbox transmission.

00mustang92 · March 24th, 2011, 01:22 PM

I put down bout 362 hp will a t45 hold that... People bout have me talked into a t56, if anyone knows where I can get one please let me know asap

ace87 · March 25th, 2011, 03:12 AM

T-45 + upgraded input shaft @ your power level should be fine. If you wanted to make it "bulletproof" you could add carbon fiber synchronizer rings, billet synchronizer keys,heat treated gears, and billet shift forks. I've got carbon fiber synchro's in my T-45 and it shifts great, way better gear engagement than stock.

T-56 is great no doubt,but if you can't get one that works for your budget, i'd go T-45

Willy Mo · March 25th, 2011, 11:38 AM

Theres a reason aftermarket companies make stronger shift forks, and shift selector arms. Bc the T-45 has shitty ones. Sure if your gonna build a 5 speed it would be nice to upgrade to billet shift forks and selector arms, but if your going to do that just buy a tko or t-56.

I agree with thre synchros, I believe they usually go bad bc of the driver. Sure they arent the strongest, but they will last a log time with decent driving.

00mustang92 · March 27th, 2011, 12:50 PM

but after id go and buy a tko or t56 with all the stuff id have to have id be looking at some good money. I just went with the t45
