Default Automatic tC, already Turbo'd, looking to add HP

Hey guys. I currently have a 07, automatic. I have the Dezod turbo s1, with ball bearing upgrade. I'm running 5 psi's but i don't beat the ____ out of my car whats so ever, so my tranny is perfectly good.
I also have an exhaust system put on. I hardly race my car, I just enjoy knowing what is under my hood, and expanding my knowledge.

Basically I was looking into adding cams to my car, then getting a street tune, and running 9psi's. Now with doing that i understand it will put some strain onto my tranny.
My question is should I look into a transmission cooler, will that help my transmission out when running that kind of power so my tranny doesn't begin to slip at all?

I plan on rebuilding my transmission in the future as well, but down the line so i'd like to take the safest route to adding more hp until then.

One of my dsm buddies said look into a Harmonic Balancer for an automatic.

Any input i'd appreciate guys, you guys always know your stuff on this forum so I figured i'd pick your brains.

Thanks guys!

1) Get a transmission cooler no matter what kit you have
2) Take your car to a qualified tuner
3) Raise the PSI
4) Valve body if you plan to go over 250whp
5) Harmonic balancer add power??? WTF!?!?! You do have balance shafts in the car already but getting the Dezod ATI hb is good stuff. http://www.dezod.com/cat-harmonic-balancer.cfm
6) Not a single person has ever provided proof that caming the tC will add any power to a street tC.

Call this number 716-681-6666 these guys can help you out. You already have their kit so you must have talked to them at some point.

Yep the dezod guys are who i delt with when getting my car turbo'd. I was going to give them a call sometime this week to see what they thought. I ws just wanted to get some input from the forums before I talked to them.

My buddy has a talon and basically said the same thing about the cams. Adding them to certain cars it might not do a thing, I was curious if any tc guys had any experience with the cams.

I was looking on dezod to pick up a transmission cooler, they have a few ranging from 80-250 bucks. Which would you recommend?

So should i invest in a hamonic balancer, transmission cooler, scrap the cams. raise the psi's? Any recommendation on the valve body?

well....May I ask a question, please ??
This is what I'm concerning, Is that gonna hurt the A/T transmission ?
Coz, I'm also interested to put on a turbo kit for my 08 TC.

PS : Sorry for asking other questions ~~ !!

Running the setup I currently am my transmission is perfectly fine as long as you don't gas it to the floor off the line everytime you drive. If you wish to put out over 250whp you have to protect your tranny and the best way to do this is a transmission cooler, torque converter, and a valve body.

I'm also curious if rebuilding the tranny would be the best option of going forward.

Mitsutmito (sp?) makes a damn good A/T Tranny Cooler.

I currently have it on my A/T boosted setup and I'm at 7psi.

Come the summer I want to be at 9psi.

You already have a trans cooler on your car. It was installed with I installed the turbo kit. Every automatic kit gets a trans cooler when they order.

Your best bet for transmission upgrades would be to check these guys out.

http://www.importperformancetrans.com/

They have upgrades. Seriously though one of the best upgrades would be to get the new APR unit we have and have paul tune it so that you can get away from the emanage blue. It's so on and off with little for mid throttle driveability. The car would drive smoother for sure.

Understandable but who's to say it's not in his budget? Your budget and his budget may be miles apart. I made the best recommendation based off of what I felt would do his car best. You know, considering I installed the turbo kit and performed the tuning with paul. ;)

-Trans upgrades for sure.
-The APR unit for the best possible driveability and control which is sensitive on an auto due to the trans trying to compensate for the additional load.
-raise the boost and retune.

very correct, and hmmm actually i had forgotten how autos are when they use piggybacks lol its been 2 years since ive seen a boosted auto so i forgot


yea if u can afford it man once done with the trans upgrades get the apr unit


DON i knwo with the autos when boosted they take longer to shifter...they usually bounce limiter once or twice before shifting can this be fixed with the unit? i was thinking maybe if u raise the rev limiter by um idk like 500rpms then u wont bounce limiter seeing as the trans brain will tell it to shift at the factory rpm point maybe this is a good fix for people?

No the unit can not fix this alone, However if you raise the limiter and install a valve body that can control the pressure properly and a torque converter that has the correct stahl for the torque he is now making you can control that issue much better. The reason it bounces off the limiter is because the transmission is sliding (and thus slipping) into gear rather than actually engaging it properly with enough transmission line pressure.

Auto transmissions operate on a few principles that are important. They are PFM (pure ____ing magic) and worm holes.

Use IPT like Don said.

A valve body your car can hold 300 without a problem... Just like Bdis said, cooler, valvebody, 12psi. The same thing that I am at right now on practically the same kit as you.

Thanks for the replies guys, as always you guys are the best. Thanks for the reply Don, so would the best route be to opt for the ecu?

If i pick up the ecu, and retune would i be safe to run 9psi's without giving my tranny a problem? My budget is around 2000, give or take a few hundred im sure i could work something in. I just paid off my turbo so I was looking into getting a few things done within the next month or two. Would i even need a valve body at all if i picked up the ecu?

the ecu has nothing to do with you needing a valvebody job, the ecu just makes drivability and tuning easier since auto tcs drive like poop when on piggy backs

he was stating that with the right stall and a vavle body up\grade the ecu would be a nice addition to the mods list because it will make your car run soo smooth

Yes. The ECU will not help your transmission but it will help to ease the power curve making less stress for the transmission. If you plan on going over 250whp you should consider the valve body a standard addition since it will not take long before your transmission starts to wear out and once it starts it dosn't stop.

Ok i understand, thanks guys i appreciate it. So basically at this point I should look into the ecu, and the valve body if i plan on running 9psi's safely on an auto tranny. There's basically no other way around it.
