Looking for peoples opinions/procedures they followed for tuning after their transmission was built. Going with a SC4/1057 and some have said load up that race tune right away, Ive heard some people say go back to stock and let it learn. Others have said start with a mild tune (Paint suggested 100hp) and then up from there.

Mike, what say you?

See you bright and early Wed :D

But, we loaded the biggest tune we had in Wendy at the time as soon as Pat got home :driving:

I babied it a lot the first few weeks, I am just now starting to really push it again, but I would say that my shifting is coming around good, and it appears to really be holding good.

I have not done any boosted launches since the rebuild last month, Just a few WOT's while already moving. :baby:

Break-in, Whats that? Oh,....:confused: I'll bet it's seeing if you can break it before the credit card bill comes in...........:D



Brake Pad's and Piston rings are the only things that I ever considered some time before WFO. Actually, Piston rings seat pretty fast with a lot of cylinder pressure.

Drive it like you stole it.

I drove back to Phx from L.A. with it set to KILL. Slowly added throttle over the next couple days.

That's a good way to do it. Load the program you will use every day ( I run 500 hp ) and drive it easy as the shifts start to clear up drive it more aggressively and so on. The new trucks learn fast on their own.

Drove from Mikes to Vegas...hooked up to my 20,000 LB trailer, and hit the east coast running 450HP tune.

That's what i'm doing right now. I started on the economy tune but quickly decided to just slowly get into it with my +100hp tune and once that is doing good I'll start tweaking my hottest tune and running it again.

There is no problem with running a full 500hp tune, but once you feel how hard the transmission downshifts are and how weird the flared shifts feel you'll know. Even if you just load the big tune in just go easy. Try to purposely hit the 405 for its traffic. Thats what I did(not purposely:D) and by the time I got back to Chris's house the transmission had relearned fairly well. Just take it easy your transmission will thank you.:hug: Have fun with it

I was only easy on it for about 2 hours to let the VB to fill back up with fluid all the way. After that it was time for the track.

Kurt but all you did was replace the stock TC with another stock TC and install the Transgo Shift kit. You didn't really up the line pressure when comparing to a fully built transmission. Im not taking anything away from your transmission by any means but your relearning process was not as drastic when going from a stock transmission to a Stage IV/Aftermarket converter.

Yes Paint u are correct i should have posted that i beilve. I didnt see where that would make that big of a differnce until now. Because i did take my c2's apart and have to assemble everything back together. But like Paint pointed out it did not increase my line pressure all that much

It did not increase your line pressure at all. What it did do was leak main line pressure ( which is greater ) into the control main circuit ( which is less )

Once Mike is done with it, just wait until about 4pm on a weekday, then drive home. You tranny will do a lot of "learning" on the 405 and the 101. By the time you get to Ventura there won't be to much it hasn't seen....other than the cruise control. Who ever said that your tranny can't learn on the freeway has never been in LA during the week...;)
