One of the best companies out there having problems. Love to hear the rest of this story.

 

Here is all you ever need to know about torque converter's ....... Lenny@Ultimate Converter Concept's !

 

you are 110 % correct ^^^^^^^^^^^^ the best out there

 

All I know is it seems these kind of threads NEVER go well for the OP. If nothing else there will be a TON of people come along to shit on you so HOLD DA FUQ ON!!!!!

 

THIS ^^^^^^

 

forget the "whp" numbers. Timeslips talk more than dyno numbers.

sucks you got screwed.

 

That Is not the only story about PTC.

 

That Is not the only story about PTC.

No matter what you are selling or doing if you have customers there will be a couple of butthurt clowns that will try to drag you down to their level.

 

I've been dealing with PTC converters for a few months now with my converter.
The short story:
Car is a summertime streetcar. Currently just a mild 400whp with a 3000 stall TC that's been flawless for 10 yrs.
Previous was a 320whp stock LT1, now it's 383 with a mild cam using same trans and TC as before. Had no problems the day I pulled the engine, reinstalled new engine and I figured something in the TC broke on the dyno while tuning. I lost all stall. Trans good works fine, shifts fine, etc. A local shop sent it out to PTC for repair. Got it back in and only had 1800 stall. So now the local shop was out of it. I sent it back to PTC myself and got it back again. I paid shipping both ways, so-called free repair. Got it back again...1800 stall AGAIN!!!

I just got off the phone with them and they give me all kinds of excuses that it was this or that and that it should only brake stall about 2500, etc, etc,etc. I was able to brake stall on the old set up at 3k all day long. Now it has just a little more hp/tq. The cam only went up from the 220's to the low 230's @ .050. So I should have gained just a little stall.

Now these phuckstiks want me to send it back again because they think they can fix it right this time. Of course, I pay shipping to and back...again.

So after talking with another TC builder, I'm gonna just get a new one from him. He even gave me the option to send it to him for a proper repair but said that it sounds like the screwed up so much shit in it already I'd be better off buying a new one.

Besides, If I were to send it back this time, I'd only be about $100 short of what a new would have cost me to begin with.
So, Live and Learn. FUCK PTC!!

You don't gain stall if curve shifts to the right.

 

Exactly, Bigger cam makes more HP and less torque curve. Less torque curve = Lower stall speed not higher.

What kind of transmission and how much did you pay for the converter? Was it a 12" 700R4?

 

You can not trash one of the most respectable torque converter builders in the whole industry over a cheap street converter that will not brake stall high enough. Brake stall is NEVER an accurate way to gauge stall speed. We can do the best we can with brake stall but it's a total gamble. You vehicle braking system and car specifics are your enemy here. A converter operates 2 different ways. It's either locked up at the desired stall speed or it's not. You're asking for your vehicle braking system to hold the converter in a place that's best for you but NOT the actual Lock up point of the converter. That is not fair to PTC at all. They probably sent you exactly what your car combo was calling for.

None of this makes any sense.

Very well said Kenny..... another company we have respect for!

 

I'm sorry for your bad experience..... however I want to take a moment and hold Kenny and PTC up! Those guys are great people (and remember, they're a competitor of ours that we happen to have a TON of respect for!) who do great work! The key word/phrase in what you've written is "they've offered to open it up again and fix anything that might not be right"..... I understand your frustration, but it shows a ton of character on their part to do this anyway (remember, you did send back a converter that had problems in the first place, it's sometimes something anyone can miss).

I can testify for every complaint (of which you don't hear many) they've got TONS of customers who have had just the opposite experience with them! So, maybe for you it's best that you deal with someone else, but to say PTC who's been doing this for years doesn't build a good piece is simply "sour grapes"!

I think this says ALOT about your character Mr. Chance! You could have at the very least sat back and let one of your competitors be bashed to death here. Instead you very professionally commented on how the situation might be different from their side and how they were a stand up company. Great job and very professional, the world needs more men like you!!

 

^^@ X-LESS
spoken for truth,, Foot Brake stall is NOT stall..

 

Not taking sides here...but has the car been down a track since PTC reworked the converter? Can't tell from the thread.

As someone said...it's time slips that matter.

Yes, It would come out flashing at 1900 and slugged until about 2800 or so. It's made for nitrous just out of the hole. The window switch is set at 3200. No one is dumb enough to hit nitrous at 1800. The N/A 60ft's went from a 1.8 (old engine) to 2.5's (new build).

Mitch, I've known about them for many years. But when they had to ask me 5 or 6 times about what kind of trans it was, in the same conversation and that they'd never seen a converter like this made me even more pissed and worried.

I'm sure if I had a PG or TH350, they'd be great. But for future reference for me, they are NOT a choice for late model performance.

Also, I know the difference between all the stalls. On many cars from TH models to 60e's, when I told the builder what I wanted for brake or flash, that's what I got, pretty much dead on.

 

What a coincidence....

i had the same problem with DYNAMIC this year--they were given every fuckin spec on my car including track data . i wanted 4800 stall , trans brake car , first time they did it, 6200 stall...........sent back on my dime , now its at 3500 . They said the same thing--"send it back " (on my dime) . I told them to GFYS = this thing is going to PTC this month .

Ive never heard anything bad about PTC before today !

 

PTC in mine and after 5 years sent it in and it was like brand new. Kenny always does the right thing. i'm 3387 lbs. and 60 foot 1.24 and 1.31 on the back tires.
If they say send it back, let them make it right. personally I think the OP fucked up and not PTC.

 

I stopped reading after LT1.

 

Lol

 

BTW Neal Chance in my small tire car and I have a 5.08% converter slippage . Marty Chance is awesome to do business with too.

 

The first time it went in I was told the clutches were bad. (it's a 4L60e). The 2nd time, they guy said "someone" cut the sprag down. They were the only ones to ever be in the TC since it was new.
They had all the info on the car from hp, tq, weight, gears, tire size, etc, etc.

The only other additional info on this is that I went to a 24x Ignition system and LSx PCM. Which required me to change the 3-2 solenoid and put in a PWM solenoid. Nothing in this would change anything when properly tuned for it.

Now after talking to the company that built my trans, even they say it's in the TC and they work with alot of customers that do 24x swaps on LT1s. They've never had an issue like this with any of their builds or TC's out of the box.

I'm no converter expert, but I'm not stupid either. This ain't my first rodeo.

I understand that PTC is good for most people. But it was funny that when I talked to the one guy, he said they don't work on much 4l60e stuff and they'd never seen a TC with the big plate on the front.

 

An LT1 and a 4L60e?

 

PTC is a great company. Let them take another look at it. If it is not right, Kenny will make it so. Great guy.

 

X2.......save the whining shit until they tell you to GFY....which Kenny will NEVER do. Give them a chance.....there's no magic formula to always get this shit right the first time.....

I just reread the first post.

Let me clear something up for my own knowledge. The converter is the same converter that you've had for 10 years and suspected it took a shit on the dyno before it was sent to PTC. Is that what they had to work with??

Yeah, I had to re-read also.

 

Anyone can have problems with even the best company so let's no be saying this guy did not have a bad experience.

 

Give them a chance to fix it, good lord, what's so hard about this concept before you drag their name in the dirt?

 

He did, twice.... and HE paid out of pocket both times, how many times should he send it?

I probably wouldn't have started this thread just yet myself but he has given them a chance to fix it.

 

PTC always treated me right!

 

Also a stock lt1 ain't putting 320 to the wheels on its best day.

 

Yes they can, I've seen one on an SD tune consistantly lay down good #'s. besides, if you were paying attention, it was cammed before since I said my cam went from 220's to 230's. But I'll simplify it for you. It had the Hotcam, 218/228 before with untouched F-body aluminum heads and a mail order tune on the stock 350.

This car isn't an all out race car. It's a fun streetcar for the wife to drive and have fun with on occasional weekends. If I wanted it to be an allout racecar, It sure as hell wouldn't be a 4300lbs Impala SS with an LT1.

Also the first time I sent it in was to fix it and make it all correct for the build I had. Cost was not an object at that time. I just wanted it right. They fucked that up. Then they had a 2nd chance with all the info AGAIN. and they fucked that up as well.

 

PTCTTF!

 

PTCTTFMF!!!

PTC is the best out there.

Take it to the track and get some data.

Putting it up on the footbrake isn't going give you much good data. Converters are far from a perfect science and putting more cam in it will tighten the converter.

 

I have to disagree with you there PTC makes a great converter but my money is on Pro torque , Neil chance and a few others . ooooooo and to the OP PTC does not suck ass
