I certainly hope your clutches aren't slipping. I haven't tried a scan as far as trans goes. I know a Tech II has a few trans RPM PID's that we can monitor. You'd have to put engine RPM and trans "RPM" side by side to see what's going on.

EDIT: Did you change the setting for tire size to "calibrate" everything??!!

Yeah, thats definitely true. Road course tune/quarter mile tune.

I agree with that! Do you ever got WOT on the course tho?

It's rare. It's such a small course you really can't get on it without the wheels just spinning or the trans slipping. I'm just hoping it's nothing serious. It only happens at the bottom of first if I go WOT without rolling into it at all.

Charlie, if you want to trade my 3.4 for your 3.6 I would be willing to do that.

I'd be concerned about the slip. Try to avoid the hole shot launches and maybe get some life out of it before rebuild time. Check trans fluid level just in case...

Just dropped the pan a month or so ago to check for shavings. It was pretty clean, a little sludge but no more than when I dropped it ~40k ago. Fluid is clean, doesn't smell burnt, and is at the right level.

I will trade $ for it. I already have a 3.4".
PM If you're interested.

You should keep your 3.4" just tune for it and keep scanning. For your autocrossing, i think the 3.4" is the way to go to rip out of corners.

If you are going to quarter mile, I would pulley up and increase timing. 2 different tunes/setups.

I made a doopy mistake. Remember the tranny issues? The 60E has a modulator with a vac line running to it. Guess how I found that vac line when I opened the hood? I never thought to look at it when I was checking the tranny fluid. Hooked it back up and all is well again.

Subject: Re: Matt's Tune Thread Sun Apr 12, 2015 8:07 am

Aaaahh yes....i love simple fixes. Amazing that caused all that trouble.

Do you have an adjustable modulator or is it still a stock style?

Subject: Re: Matt's Tune Thread Sun Apr 12, 2015 8:11 am

Adjustable.

Subject: Re: Matt's Tune Thread Sun Apr 12, 2015 8:14 am

Cool....I always thought that was a good $12 spent on my car...

Subject: Re: Matt's Tune Thread Thu Apr 16, 2015 10:34 pm

Found a guy over on GP forums selling a 3.5" for $20, so I snagged it.

Subject: Re: Matt's Tune Thread Thu Apr 16, 2015 10:42 pm

Nice! can't wait to see some scans with that. can you post a pic of your hot timing table?

Subject: Re: Matt's Tune Thread Thu Apr 16, 2015 11:12 pm

I'll post it when I'm done messing with it

This. One of the greatest "doopy" mistakes. You think the car is going to die, and you find something stupid causing the issue. I actually love when this sort of thing happens. Certainly beats rebuilding a tranny.
Glad to hear it's fixed!
