I think this trans is going to have to be built to handle those extreme shifts

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.

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.

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!

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.

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.

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 ).
