I finally got the engine/trans mounted after substantial modification to the tunnel. Anyone attempting this will end up 4+" from the firewall with a small amount of mods, but I got it down to 1" and should be at almost exactly 50/50 weight distribution.

Looks like I will have a pan about 2" deep and can build a low profile sump.

Line on the pan is level with the frame rails: http://picasaweb.google.com/boetye/T...67709810924130

Hi CT, good to see man!

What car is this in again?

FYI - to make things simple, go for a VE Commodore/G8 trans pan and filter. It will bolt right in and reduce your pan depth by about 3/4 inch at the deepest point.

If you cant get a G8 pan in the US, let me know. It is probably the same as the Cadi pan though.

The filter has been designed with minimum clearance in mind, and snugs up right against the valve body, with recesses in all the right places for bolt head clearance etc. I will post some shots when I have time. Just finished revising the 6L80 VE/G8 pan to fit the 6L90.

Cheers!

Project car is a 2006 Pontiac Solstice. Awesome news about the pan and filter! So is the new North American G8 pan and filter the same as the VE Commodore?

Any pictures would be helpful.

CT....mmmm....yes the Solstice supercar. Cool!

Here are a couple pics showing the VE Commodore/Pontiac G8 6L80 pan which I have adapted to the 6L90, and gained about 3/4" of clearance over the 6L90 stock truck pan and the and the Corvette deep 6L80 pan.


This is the view from the side of the 6L90 showing the 6L80 VE/G8 pan installed on the 6L90. A spacer was welded in to cover the gap at the rear. Luckily this works simply with a flat piece of steel shaped to fit against the 6L80 pan and fits the profile of the 6L90 pan rail.



Quick shot of the deep end of the VE/G8 6L80 pan showing the depth at 65mm. (2.56"). The filter for this pan has undergone considerable revision by GMPT to get it snug right up agains the valve body. It has recesses molded in for bolt heads etc to make absolutely sure no vertical space is wasted.


The journey continues.

Cheers!

Thanks!

I think I will order one and start from there. I should be very close with that pan and filter.

Nice work!

Forgot to check.. That would be the 24236930 filter and 24228399 pan correct?

CTex

rsz288

mmmm....yes forgot to include the PN's didn't I....

The part numbers were:

Yes 24236930 for the filter

And 24239528 for the pan. (if i recall correctly, this is a revision from 24228399....or there was a running revision based on VIN.)

It may have been simply a change to the level check plug. I noticed that the shallow pan uses a different oil level setting than the deep pan. i.e. the shallow pan correct level is 1-2mm below the pan rail, the deep pan is 18mm below the pan rail. Obviously the level is flexible......and mainly set to give a reserve in the pan at a certain height or volume above the filter....

Another PN which may be of assistance to anyone looking at this conversion, is the GM trans cooler lines:

92190644...for VE Commodore, and likely G8 also.

These lines come as a fixed together pair and run up to the front of the engine.

Am sure almost any 6L80/6L90 lines that pair with a GenIV engine would work...

And....the trans vent: 92206339. This is an assembly that comes with two check valves that let filtered air into the trans at one end and exhausts excessive pressure out the other.

Anyone else out there looking at or doing this conversion?

Cheers!

Went to my local dealer (Canada) and found out that the filter number has been changed up to 24252158 at least in this part of the world. The pan number is still the 24239528. But both are not available in North America (yet?) The VE has been out longer then that G8. Maybe that's why. Guess I need a dealer from your area to ship to Canada.

CT,

Apologies, but that is quite funny, the pan has "Made in USA" on it. The mysterious ways GMSPO operates . The filter is "Made in USA" too.

Dont hesitate to PM me if you want one or both shipped, and I will organise for you.

Have a good one!

Pictures to come, but the 6L90E transplant into the 68 Camaro is now in action.

Trans operates as planned, and with the LS7........well the power is a tad more than adequate....as Rolls Royce would say...

The last couple months has been solid with trying to fit some progress on the car in between very hectic work weeks and weekends!

But with the exhaust system done, drive shaft revised to fit the monster slip yoke on for the 6L90, shifter built, radiator in and revised for the LS inlet & outlet pipe configuration, installing all the electrical back in plus the computer and harness, fuel system complete, new booster and master cylinder and brake lines, and front sheet metal back on, and a new program loaded in the 6L90, it drives very nice.

For anyone interested, the shifter is rod actuated, and uses a 4L60/65 shift rod, re-set a little to fit around the rear of the trans case, and couples to a simplified shift mechanism which draws from the design used on the Pontiac G8's & VE Commodores.

More work to do to clean up a few areas (like get the park/nuetral and reverse switch controls running), some of the electricals, and some new seats, and cruising is looking good!

Cheers all.

who did the programming of the trans module?

rsz288

Hi Jay_lt4,

Looked after that flashed personally. It will take some fine tuning for the Camaro being a lower weight vehicle than the VE/G8 the calibration came from, 3100lbs vs 3900lbs, but it is working fine so far.

Cheers!

How are you going to control the electronic/shifting etc on this transmission?

rsz288

To tell the truth it does quite well by itself....being an auto....

Seriously do you mean calibrations/shift points/firmness/etc etc., or do you mean manual shifting like paddles: TapUp/TapDown ?

Cheers.

Good to hear you're up and running! Keep the great pics coming!

so there is software availible to change the shift and pressure settings in the tcm?, do you have full control manual control of the gear shifts,

Thanks John. Now that the car is mobile, must get it on a hoist and do some good shots of the underside.

At least when people ask now about whether the 6L80/90 will fit in a Gen 1 Camaro, the answer is a conditional "yes"

Yes EFILive and HPTuners tuning software access several hundred parameters for the T43 controller in the trans. Though they are not simple having a "clutch to clutch" design where all clutches are operated electronically.

There is a growing number of tuners around that are building very good expertise with these trans' and those software packages.

"Manual" control is available by tap shifting paddles/buttons. Tap for up, tap for down. There are a couple of modes for this, most cars & trucks with these trans and paddles or a sport position on the shifter use an indirect mode via the CAN bus.

Though there is really no need to worry about manual shifting. Most who are racing these just let the "tuned" trans do its thing automatically.

i.e. a twin turbo daily driver 4000lb car & driver running low 11's, self shifting, what more do you need?

Cheers!

Still to get together some better photos of the underside of the 6L90 installation, but thought many may be interested in how the "instrumentation" question was addressed for both the LS conversion in the 68 Camaro, and the specific need of having some idea what the 6L90 is doing.

A picture is a thousand words as the saying goes, so here is a shot of a genius little device "Dashdaq", which in total, can give access to over 900 GM parameters (a mix of included and optional).

Shown here is the shift lever position "Reverse" TRGR, the current commanded gear "3rd" on the dial "SHPR", a torque converter clutch status parameter, trans fluid temperature "TFTR", and the current base pattern "Default" selected.

The labels are customisable.



This is one screen of about 10 or more, with various gauges which can be allocated GM ECM/TCM parameters via the touch screen.

Needless to say, one screen is setup as Speedo, Tacho, Temp, another with fuel economy, temp, throttle position, etc etc., another with more trans parameters, i.e. actual shift time per gear change., MAF, MAP, Knock, Oil, and more.

The good thing about all these, is that everything on a screen can be logged to SD card at the click of a button, and DTC's can be read and cleared too.

There is nothing new re this shot, the are some excellent and definitive threads around on LS conversions into Camaros and many other cars, but there is a 6L90 hiding behind the engine ! Still some tidy up to go!



More to come on some 6L90 underside shots when we get the car up on a hoist next!

Oh, and incidentally, now that a good calibration has been loaded the trans is driving really well. Around 1500rpm at 60mph. 500 miles will be up very soon. Mileage is excellent at cruise.

cheers.

I bet your happy now mate now if you need to clock up a few miles and need a passenger you know where I live.
