Can't believe no one here has mentioned Frank at CPT. The LT1 guys over at another board love the guys work. I'm having one built by him now. The race rebuild will handle anything you can throw at it.

I have an FLP in mine, no problems yet.

Why would you screw around the line pressure?
What happens if I leave this tables stock?
It just commands a certain pressure for a certain TPS, this depending on the oil temperature.

What happens in a cold winter morning using a vacuum modulator?
Will it adjust for more ATF viscosity or will it shift too hard until you reach a normal operating temperature?

Imagine a cold start in the snow with too much pressure: you just spin the wheels!

Here we have 15F in winter (lots of snow) and 95F in summer and my car HAS to bahave the same in every condition. It's a daily drive 365 days a year.
I tuned the engine to do that, now I'd like the transmission to do the same.
If a beefed up A4 can't do that I'll better go with a M6...

I wouldnt purposely mess with the line pressure tables...just pointing out that a mistake there can wipe out a tranny. A built tranny can keep pcm line pressure control...I just wouldn't do it. At your power level, get a built up tranny..keep pcm line pressure control and be happy. you could probably get a stock tranny with a shift kit and torque management to last a long time

My TM was set to remove 50% torque at max power...
I also have 55000 miles righ tow, maybe it's jus normal that it brakes.

The rear end is a 2.73. Can this also shorten the life of the tranny? (stupid question, OK)

cablebandit

iTrader: (37)

actually yes...2.73 gear is rougher on the tranny than a higher (numerically) gear like a 3.73 but should not be a problem at your power level.

In the early years folks jacked up their line pressure too much. I think my old sticky has a discussion about this. I would not increase line pressure much more over stock.

Run a good transcooler and the trans will live. My FLP lived for several years going low 11's in a car driven almost every day, and when I pulled it, it was perfect inside.

THis of the cooler may be the biggest problem. Before installing it and adjusting the fan settings I used to see 220F or more.
This during years. Now I'm at 190F in summer, but maybe the tranny has been toasted before and adding the blower did just shorten its life even faster.

------------------

OK, I started this thread asking where to buy a beefed up tranny.
Conclusion: trannies in the States are cheaper than here, but I have to consider $600 shipping (assuming I installit myself).
At the end it costs the same, plus if I buy a crap I'd better trash it because of the additional shipping costs.
I find a shop here with a guy that learned how to repair trannies in the States: he has all the special parts on stock and he's doing only this kind of repair.
Unless I make the A4-M6 swap I'll go with this company.

Thank you guys for all your comments!

You really can't go wrong with a transmission from FLP as they have shipped many transmissions over seas.

Look at your avatar: something similar will show up soon in my console...
No more automatic - back to the roots!

Keep in mind that the 6 speed trannies have their share of breaks as well and they can be very hard on the rest of the drivetrain.

I'd give Carl Rossler a call and get his opinion before making that swap.

That's just my opinion. Good luck either way.

A T-56 can be built to take some abuse... trust me. Either way, Chuck at FLP can build you a trans than will fit your needs.

Extreme Duty T-56
Cryogenically treated Viper main shaft
Viper steel 3-4 shift fork
Carbon fiber blocker rings
Billet syncro keys

Oh I know the T-56 can be built to hold a ton of Hp, but if he is planning on making the swap to a stock T-56, then that's not a wise move unless he has access to a good T-56 builder over there. Otherwise he is in the same boat.

There are some good 4L60E builders here that would do him right no doubt.

We just have it too good don't we?

tici

iTrader: (1)

Well, I'm not planning to abuse the T-56, it's a daily drive with 450HP at the crank, that's it.
No drag raging, no burnouts... home to work and some nice rides on the weekend.
Somemtimes in Germany on th Autobahn but nothing special.
I know you guys are thinking at a sporty application but in my case it's just a normal car with a "little" extra.

TXCAMSS

I'd definitely go with a quality built 4L60E. I don't think you could tear up a top level FLP or a Rossler built 4L60E. It's a pretty install.

Personally I'd call the builders and get a feel for what kind of shipping costs there may be and go from there. Good luck either way.

tici

iTrader: (1)

I checked the prices and at the end a built trans from the States costs as much as a rebuilt (beefed up) over here.
OK I may save max $500 if I go for the cheapest...
But here I can kick the builder's butt when something goes wrong, not over there

Hey, I found a great transmission shop here in Oklahoma. The guys name to talk to there is Craig. He specializes in 4l60E's. He has shipped units worldwide before, last one he sent overseas went to Amsterdam. He can tell you anything you want to know about how these things work. You can reach him at zatar1@yahoo.com

I think you guys are paid by those companies
I'm sure they are all serious tranny builders, but...

I AM GOING WITH A STICK

I want to decide when the car shifts and I want more flexibility than with 4 speeds. 5 would be fine, 6 is ok too.
