Take my poll! Final TC decision!! Ok you guys have me extremely lost! I am looking all over about torque converters.. I am looking for the best Daily Driving, Most Effiencent, and Streetable converter at the best price! I think the 4000 STall is best for me.. correct me if i'm wrong!
1st i say a Yank SS4000 or PT4000.. and they are pricey.. But then i read in many forums that the TCI actually put down a better MPH and was putting down more power!
Then i think alright i'll go with a TCI 4000 stall.. and i hear a lot of good things about them! except for yank owners bashing them.. but then i questioned myself whether to restall my Vig3200 to a Vig4000..
But then i heard the Vig4000's are VERY loose and EXTREMELY inefficient..
So i am leaning towards TCI but i'm not sure which TC will net me a better time for a better price!

I say go with the Yank PT4200. It's a very streetable converter. My wife has one in her SS and it's sweet. I've also had the ST3500 and it was great, but it hit real hard out of the hole and created traction problems when the track wasn't perfect. The PT4200 is as tight as the ST3500 as feel goes, but we gained ET and mph with it and got a more controlable launch with 1.42 60fts. The Yank converters are the best IMHO. There's just some areas that you don't want to cut corners on and the converter is one of them.
The Yank SS4000 or PT4000 would be a nice choice as well, but I don't have any personal experience with them. FWIW- My PT4200 shift extension is at 5600 with 3.73 gears and a 28 inch tall tire. It brake stalls up to right at 2800 rpm and flashes to 4200.
Your best bet is to call Yank and talk to Mike or Dave and get there opinion as to what the best choice would be for your application.
Good luck!!

I was running a Yank PT4400 but it was too loose for me. Now I am running a TCI 4000 and for the money it is the way to go. I shift at 6400 and the RPM drop to 5400 between shifts.

Keep the converter you got and put in 3.91 gears. That will raise you shift extension by 200RPM alone. Or, go the SS3600 with the 3.91 gears. Its has a high STR which means more slip and more torque multiplication.

I'm glad to hear the 4000 stalls are working great! no matter which company!.. But i really don't want to change gears.. I like whats in there and don't really wanna go any bigger.. I drive the thing way too much.. i don;'t know how big of a difference it would make.. but i just want to try a different converter also! Thanks guys!

Changing gears for that little bit is not worth it. The bigger converter will yield more gain anyways. The SS4000 drives like a 3000 on the street. It is when you hit it that it acts like a 4000 stall. It is very efficient and I run cooler with the SS4000 than I did with the MW3600.

Everybody's idea of "streetable" is different. Me, I
wouldn't like the 3.70s let alone the higher stall /
slippage of a 4000 and couldn't hook up the inevitable
2.7:1 or more of STR anyway. It's the tires and the
traction your suspension will get you, that point to
the proper converter STR and the engine powerband
that point to the right stall speed (which w/ STR sets
the shift extension, at a given engine torque level).
A converter is always a compromise and the goals do
not seem to match all that well, the converters you
are looking at (thinks I). Unless the more important
ones are left unstated (like, you want a "streetable"
converter that will pull the wheels on slicks with a
full drag suspension). Which may be the case, given
the mod list. But in that case "streetable" would be
a very relative term.

Yea i get what your saying! That STR is extremely high haha.. it will be very hard to hook on the street.. But since i have the 9" w/ locker.. and i am getting a CF DS soon and building my trans.. I think with slicks on or ET streets at the track.. it will be insane with an SS4000!
But i've also been ready colonels post on the SS4000.. and he said its pretty tight on the street and pulls like a raped ape at the track! but i guess i'll have to find out! haha $825 worth of finding out lol..
Do you think my shift extension will work out though jimmy blue? with me making max power at 6250 and max torque from 5000-5800? should drop me right in there correct?
Thanks for your input! i appreciate it!

funny thing how Yank is what everyone picks on the poll. man go with the Yank, if want nice launches and still streetability than get the PT4000, I drive mine everyday and drive to the track and then cut 1.54-1.55's all day long

well i heard the SS4000 is more driveable on the street because it is tighter.. i keep hearing the PT4000 is pretty loose.. The SS series is supposed to be for streetability and pulling like a raped ape at the track!
This is what tByrne Posted on their tests from the SS3800!

Just go into the tranny section, scroll down, and read up! Its good information! favoring the SS series
!
Thanks for the comments guys! you definately pointed me towards the right place.. which is yank.. and then the stall speed and series was all up to me! Thanks

Someone from Yank posted on here the SS and PT will 60' the same but the PT will have a car on the end. All things equal. I got a monster Yank that has a shift extension of 6000. Its an animal at the track and my wife still drives it everyday.

Yea i have heard many good things about both PT and SS verters! i just heard the SS is a little more streetable.. i heard they are both crazy from a roll! But your times are awesome! You have a 12 bolt or 9" rear? Built trans? let me know your set up a little more.. shoot me a PM if ya want!
I just got a SS3600 put in my 2001 Trans am w/ 3.42 gears, Pacesetter headers, Hooker exhaust, induction, sub-frames, aftermarket torque arm, and box welded LCAs. I love the way it drives on the street, you can hardly tell it's not a stock converter. I have to give the car a little more gas to get moving, but after that it's almost like stock. I'm sure the SS4000 would be along the same line, it has a higher stall but also a little higher STR. I got a hell of a deal on my SS3600, found a guy on here that had one brand new in box. I picked it up for $640. If you don't want to pay a new price just keep looking, you'll find someone with a torque converter to sell, but I would definetley get a Yank converter. They simply make the best!
