My 4L60E is starting to slip. It has 77k miles on it with plenty of racing so im not surprised. Should I rebuild it, and how much would that cost? Or swap an M6 in it? Id really like to put a t56 in it but ive never installed/adjusted a clutch, neither has my dad. And most tough jobs ever done to my car has been headers and A/C. I really dont know if I can handle such a job.

What do you guys think, the T56 has alot of perks but I just dont know if i can handle doing all this stuff, which would have to been done in no more than a week after from start to finish.

Rebuild. Go to the link down there....

I agree with Frank a properly built A4 will be more consistent in the 1/4, and easier to launch then the M6. The A4 does better in stop and go traffic then the M6. The M6 is fun to drive but if you start getting to the point you need a high hold clutch for the increased power/torque when you mod the motor then that fun goes away a little due to the heavy clutch pedal. Plus on top of all of that it is cheeper to get the A4 rebuilt (by a good builder) then to go through the M6 conversion.

I say a good builder because if you get tthe local shop to do it you will be waisting money and never getting it finished, just search this forum and you will see that! Or look for RacingTiger04's posts!

 

I agree , check the link in my sig.

 

Frank, I'm also looking at your website and I have a couple questions. I'm trying to finish my planning for the cc305 cam in my budgeted 96 Z and I'm down to figuring out the tranny details. I was reading your "performance rebuild" and I think that may suite me since I dont race but wasn't sure. Also..wondering if there was any "hardparts" that you recommended.
I guess you need some info from me..
My 4l60e has about 114K and still running strong. The car is a 96 Z city/backroad weekend driver on a budget and I want it to be able to handle somethat agressive treatement. I plan to keep stock heads and I already have some basic bolt-ons. I'm also planning 3.73's. I want to keep my low to mid..that's why I kept the shorty headers and picked a cc305 cam. I was also wondering what torque converter you recommend as I was thinking maybe a 2800 stall?
Anyhow, any help in the right direction would be great.

 

CC305 cars are capable of running in the low 12's pretty easily...Because of this, I would HIGHLY recommend the "race" rebuild. For the parts that are included for the price, you can't beat it.
Go back to the web site and read exactly what "hard parts" means. HP's are parts not normally replaced in a normal rebuild. We only replace them if they're damaged. HP's would include something like a planetary, drum, sprag race, etc. There's no way to tell what HP's are bad until we get a transmission apart.
As for a converter? I'd go with a ProTorque 10.5" 3200 stall in your application.

Thank you for replying to my questions. I'll check out your website more thoroughly when I get off work and hit you up if I have anymore questions.

 

I have noting but good things to say about my Trans and ProTorque 3200 stall converter! I hammered the gas today and still can't belive how much it woke my car up compared to the stocker.

 

Alright i didnt want my thread to turn into a damn CPT advertisement i just want some opinions on either A4 or M6 not where to get one rebuilt. I live in Texas and we have plenty of fast cars and reputable shops...

 

I advise a rebuild since it's alot cheaper. I might hit Frank up for service but your lucky that your alot closer than I am for you to send your A4. I'm way over here in California and freight costs for me is deadly so I'm stuck on decisions.

 

I did an M6 swap and haven't looked back. Its 100X more fun to drive since its a street car and I only go to the strip for fun so timeslips don't mean that much to me. And 6th gear is nice on the highway, 2000 RPM's at 80 vs 2900 with the A4.

 

How long did it take you to swap everythng in/out

 

It wouldn't have been too bad if the bearings weren't spon in the first tranny I got. Then the 2nd one was damaged in shipping, but the 3rd is working out fine so it took me 6 weeks . If there wasn't any trouble it wouldnt take that long. It took me about a week doing it when I had time between work. Its really not that hard, just time consuming. The hardest part was the pedals, the rest was pretty easy. You could probably do it in 2-3 days if everything goes ok and u have the help of a friend.

 

Z06Z28 - Here are a couple threads aboput shipping your tranny, from California to CPT 1, from California to CPT 2, and this has a lot of shipping info.. Good luck!

And to Robert95z, sorry to turn this into a CPT ad, but think about it.. If you wanted info about a rebuild or swap then why not give you info about the best possible rebuild? And my original responce above still stands! Good lock with whatever route you choose!

By no means am I trying to talk you out of an M6 swap I was just giving you info that you can easily find, if you reread it you will see I give advantages and dis advantages of both, but in the end it is your car and your decision..

 

John,
Thanks for the input...but...I think this is one guy we should let take his trans to one of his "local reputable shops". Then like all the others that have them done by "reputable shops", he'll be on here a week after getting it back asking why his transmission doesn't work the way he wants it to.
You gave the guy the info about where to send it to have the best rebuild done. If he chooses to go elsewhere, it's his money that he'll be wasting.
