I think this trans is going to have to be built to handle those extreme shifts
Hmm maybe I should bump it down....
I'm planning on beefing up the tranny next summer. I think the GM reman I have has about 40k on it right now.

That GM Reman won't hold it for long. Don is right about the RPM limit. I've spent alot of quality time getting dirty with my trans builder.

You may want to seriously consider toning that down a tad.

That is sounding like a good idea....

Ok I've got some good news and some BAD news.
Today I just got 4 new chips.
Each increased the timing by about 3*. So it went 24*, 27*, 30* and 33*.
I tried all the chips in order and I was able to run 34* of timing with NO KR.
That'* 15-17* more than stock!
Now for the BAD news....
My trans is slipping WOT at 6400 rpm....
I knew it was going to happen sooner or later but it still sucks.

So how'd it feel, other than the slippage, at 34*? Did it feel like there was quite a bit more umph w/34* vs the 24*?

Yeah it did pull more. I think I read somewhere that every degeree of timing is 1-2hp?
It felt something like that.

Are there any nasty side effects to consider when increasing the timing so much? I almost find it hard to believe you could run that much timing without KR!

Basically, that means I can get WAY more timing than my INTENSE PCM is running. I definitely need to go more aggressive with my parameters.

Dude, get that thing to the dyno already!

*Just in case* Timing advance is the measurement in crankshaft degrees that the spark takes place before it reaches top dead center. It takes time for the mixture to detonate so you want to spark before it reaches TDC. Then it will blow up after the piston reaches TDC. *
So, yeah, you can advance the timing too much. You can actually detonate the air/fuel so that it pushes the piston in the wrong direction.
You may be able to advance the timing more but probably not by much. You need floooow to be able to really up the timing.
Dyno? Yeah soon but I want to do something about my tranny first so it won't take a dump on the dyno. Man I'm so pissed right now.

Don't be angry; we all know that the tranny is the weak spot in the drive train. If you drive hard with increased power (as in your case), you know that sooner or later you'll have to deal with the tranny. I know it means big bucks, but you had to know this was coming.

Look at it this way: if you redo the tranny now and have it beefed up similar to Bill'*, you shouldn't have to deal with it for a long time, if ever. Figure out a way to finance the operation, then get it over with. You'll have a rock solid car you can keep on the road for many, many more miles.

Believe me I knew it was comming.
I really have no way to afford a built tranny right now and I'm not going to waste my money on an average rebuild either. I could possibly take out a loan but I dunno....
For right now I'm going to get an adjustable trans modulator ($17) and maybe a bottle of lucas ( $8 ).
