You're going to need to provide more information to get a converter built for you. Check out our online build sheet and fill that out. We can make a converter recommendation from that info for you.

I'll answer your question...Typically to make the 97 4l60 work with your 08 LQ4, you would first need to swap the flat flex plate and the spacer out for a dished style flex plate with the 10.75" bolt pattern. Most aftermarket stamped steel flex plates have this pattern, and they're pretty affordable. Since you already have the spacer from the lq4, you can run it between the 4l60 LT converter and the LS style dished flex plate to center the LT 4l60 converter.

By going the custom converter route, you can bypass some of this, but we understand not everybody is looking to spend $800+ to get their swap project rolling.

Do you guys offer a torque converter that would work with that?

To me the real question is: what is the condition of the '97 4L60E?
These older units are notoriously weak and when hooked up to a much more powerful LS engine, it won't last long, especially if it has many miles on it.
Of course, if it was recently rebuild with performance parts, then it should last.

EDIT - However there are more compatibility problems - see below.

I rebuilt it with parts rate up to 500 hp and 450 torque, the only reason I'm using that trans is because that what I had on hand.

They didn't make an LQ4 in 08.

Which means you're in Gen 4 territory, so unless you plan to either convert it to a manual valve body or run a stand-alone controller, then figuring out which converter/flexplate you need is completely pointless.

Good point!
I have no idea of whether they made an LQ4 (6.0L steel block) in '08, but any vehicle with a ECM/TCM combo (starting around '06 and probably all by '08) requires a 4L60E/70E with ISS (Input Speed Sensor). This TCM requirement cannot be disabled or "tuned out".
So you really need a '06-'08 4L60E/65E/70E which has ISS.
'09+ are electrically different and incompatible with earlier TCMs and even harnesses.

Lets say it is a Gen 4, and not just a case of misinformation on the lq4 model year, what all would have to be done to convert it to run on an older style computer? I can't imagine it's too extensive.

Lingenfelter conversion box, an older ECU, and a Gen 3 wiring harness with trans plug.

That's the bare minimum, though. It will make a Gen 4 run on Gen 3 wiring/PCM and control the 60e. He will still have the VVT/DoD issue to solve, have to decide between DBC/DBW, etc.

As far as trans goes, the $250 conversion box will convert the 58x/4x signals to 24x/1x for the Gen 3 ECU. 97 was the first year that a 60e is 100% to work with a Gen 3 ECU, before that the torque converter lacked PWM control. 96 Can be made to work depending on what the transmission came out of.

JoeNova is spot on (although I think most '96 4L60E are PWM)

I suspect that the OP will decide this is MUCH more complex than expected.

Alternatively the trans could be upgraded, but will require a 300mm ISS input shaft/drum, ISS pump, ISS sensor, internal harness and perhaps a few other parts. And a 4L70E harness to the TCM. It would also require a LS-style bell housing unless a custom converter is used.

It really might be cheaper and certainly easier to find a '06-'06 transmission; just make sure it has ISS.

In that case you don't need ISS, and Circle-D_Brian's comments apply.
You may only need a modified flexplate and a spacer to your your trans and an LT-style converter. Or could order a custom converter from Circle-D or FTI which will have the LS-style pilot, but accept an LT-style input shaft.
