Question Drivability with PT4400 and 3.42 gears?

Just like the title says, what kind of drivability can I expect? I don't want to run 3.73s as I drive on the highway alot and don't want to turn too many rpms and I won't run a taller tire since this is my DD. What rpms can I expect for the car to move with the 3.42s? Thanks in advance.

I run mine with 3.23's and it's extremely loose compared to my SS4000. It'll move slowly at 2000-2500 RPM's. Staying with traffic takes ~3500 RPM's. I'm getting 3.90's or 4.10's in the spring....I can live with the 3.23's, but I really want the higher gears to tighten things up some. Even with it being so loose, it's still my favorite converter by far from the three that I've had. It pulls hard from any speed. This is the converter that contradicts the highway racing with an A4 stereotype. You'll love it.

It was pretty tiring after a while. I did a YTP 4200 on 3.23s.

Programming can help. Raise your part throttle shift points for 1-2 and 2-3. Keep your light throttle lock-up speed low. use 3rd gear lock-up too.

I know the drivability is good with the PT4000 and 3:42 gears with a stock internal LS1.
I switched the Vig3600 with a SS4000 (Yank) and loved it,but lost the lock up clutch after about 15,000 miles. So i replaced it with a PT4000(Yank) and found it is WAY looser that the SS4000 was driving in town is a little harder. Too little throttle and you can't keep up in traffic and TOO MUCH throttle and you have to constantly correct throttle input. (on the gas and off the gas)
But goes like crazy at WOT.

seems like anybody with a Yank PT 4400 would normally not be too concerned with driveability especially on the HWY!

Well the lockup will help with the driveability on the highway, it's the city driving that concerns me because of how high the rpms need to be in order to get the car moving with the 3.42s. Just trying to decide if I should stay with the converter I have now or upgrade to the PT4400 when I get the built trans.

Any chance you can drive someone else's car with that set-up down by you?

I really liked the street"challenges" after i made the change to the PT4000 from the SS4000. Traction was easier to find with a little less STR.

I am adding a H/C set-up this winter and was thinking about upping to the PT4400 and losing the spray all together.

Good luck.

No idea, usually people just go with 3.73s. I'll have to post up in the FL section and see if anyone has that setup. May be hard to find since the car is also cammed yet has stock casting heads.

What do you have now?

Florida is pretty damn flat. Around here it is hilly and that is where I tended to notice the looseness was going up hill. Your exhaust looks like a pretty loud set-up, that makes it seem looser because you really hear the car.

I don't have any issues with my PT4000 and 3.42's but I don't drive mine that much.

If you set your T.C. lockup points correct you shouldn't have a problem on the high way with any stall speed converter. Around town however is another story, it will take a lot of throttle input to get the car moving with stock gear ratios. It will be lazy at low rpms in 3rd and 4th. You will have to stay in 2nd and 3rd and shift into over drive your self.

What do you have now?
With 3:23s or 3:42s the 4400 is going to be loose,it also pretty much all out low ET producer at the track.My car is not a DD so 4:10s and PT4400 work well[1999/21,000miles].I have had Yank 3500 with 3:23s[little feel of slippage]drove my buddies 3500 with 4:10s[almost no feel of slippage].Yank 4000 with 3:42s[great all around street/strip combo,no where near the feel of the PT4400].
Like REDSS said,be nice to drive one and get the fell of it.

Sorry guys, thought you checked my sig or clicked on the pic to see which converter I'm running. Still on 2.73s and Yank's SS3800. On the highway it's no problem because of lockup but in city is what I'm concerned about because of the looseness of the 4400. If someone can give a good guess, how many rpms would it take to move the car with the 3.42s and the 4400? Right now it takes 1700 rpms to move the car slowly with the setup I have now. So if it takes about 2300 rpms to get the car moving nicely with the new setup, I'll go for it, 3000 rpms will be too much and too loud obviously

Even with 3.42's...it's still gonna take at least 3000 RPM's to move the car at a decent rate of acclereration. See my post above.

I hope you dont have duels, driving around the city at 3000+ rpms would get very annoying for me.

I guess we have to define decent. 3000 rpms will pull away from normal traffic very easily.

Raised shift points really helps, because 1st and 2nd gear respond pretty well to 2400 rpm input.

I totally agree I have 3.23s and a 3000stall and when im taking off normal city driving it revs to maybe 2500 but it gets rolling good and I dont have to hardly give it anymore gas. I will be getting 3.73s soon and maybe a 3600stall but im not sure I will do the 3.73s first and go from there

Yeah but we are talking about the PT4400 which is extremely loose compared to your 3000 stall.
2200-2500 rpms sounds pretty good for the 3.23s, it will be just a tad bit lower with the 3.42s..........
