I believe the E153 tranny is a direct bolt to the 3s motor just like the s54 tranny does. And i would advise you to rebuild atleast the head when you purchase your new 3s motor because common sense--if you're going to sell you motor, you're gonna wanna beat it around before you do. So it would be a smart choice, plus while you're at it i would also advise to purchase w/e harder to install mods you can since the motor is already out of the engine bay such as your new camshafts, port & polish, decarb and clean out the motor, etc.
And ofcourse when you rebuild the motor it's gonna make the motor run better. Also, you can't use your 5s-fe ECU with the 3s motor, you have to use the 3s ecu and flywheel and clutch, but i'll assume the clutch already in the e153 tranny is compatible.
*edit* you also have to use a st205 gauge cluster as well, your GT one won't work with it.

ic ic so does the E153 tranny bolt up to the GT frame? and how do you go about tuning the ECU? can u just plug it into a laptop and buy a programmer some were?

I believe the E153 tranny should bolt right up to the GT frame but don't count on my advice on that one. I'm not too sure myself, you might have to do a small mod like replacing a shift link or cable or something but not sure. Hope someone else with more expertise can answer that question for me.
And what do you mean by tuning the ECU? I don't believe you can flash the ECU for our ecu's are not EEPROM like honda's ecu's are. However, you can get the speed limit defencer so if you get the 3s motor, you're allowed to go over the 120mph mark, and just get yourself a s-afc or NEO to tune the a/f ratios and such.

Do a search for "e153", there are many topics about this.
Yes, that trans does bolt up to the motor, but you need to buy new motor mounts, shifter cables and make custom axles. If you choose that path, make sure you do ALL of your research, because a lot of people who didnt, end with axle or shifting issues.

The 3sgte runs off the 3sgte ecu. You swap that out with your existing ecu.
There is no need to tune anything. Its a factory turbo motor, already tuned by toyota.

Jee, i haven't really done much research upon the E153 tranny swap because i plan on getting that tranny next year when i get the 3sgte motor but I didn't know you had to make custom axles, how do you go about doing that? that'll probably cost a bit right?
I'm interested in comparing the gear ratios between the two tranny's.
Also guys, I would trust in lago's advice, he's practically a mechanic himself!
