Just curious as too how this is going guys , im still all in for a 6 speed swap , specially if it works with tapshift allready.

Any new info here? I am attempting to put a 5.3 Gen IV (58x wheel) with a 6t75 trans into a kit car.

How about a Recap?
of All of What is needed,
What has been Solved,
What needs to be Solved?
so we can work on what needs to be worked on,
and not work on something that has been Solved?

Probably never going to happen. Lets put the r&d into a manual swap from a g6!

TrueBlueGTO

I can't speak for anyone else pursing the project. But the summary seems to be:

A) A custom oil pan is necessary to properly relocate the starter
B) A theoretical ECM/TCM solution is a possible solution to the 58x motor working
C) A custom adapter is necessary for the trans and FWD LS4 motor.

Speaking from my end. Making the custom parts is the easy part. But if the CAN bus systems reject one another, then additional programming R&D will be necessary. If someone has the engine and trans I could assist in testing "B" but someone has to take the plunge first to get at least those two.

I have a better Idea for a transmission, a T56. Now before someone boo hoos about a RWD conversion not being possible (like those with no fab skills always do) watch the videos. In a few years when my car is worn out I will be attempting this....or ruining my car in the process. These cars should have been RWD from GM, a FWD V8 is such a shame.

Yeah, it'll happen. See below.

A is not necessary as shown here:

The 6T70/5 have a little pocket on top of the transmission.

Here's a video of an LS2 + 6T75 matted together and turning over:


B is possible as you mentioned over the phone. However, like you said, there are issues with the E40 24x cars.

The same guy who put the above stuff together is a PCS (Powertrain Conrol Solutions) engineer working on getting this transmission to talk with ALL of our vehicles (and others). Apparently it's done. It's all a matter of testing and torque management.

C is not a problem and is done as well (yellow and cyan parts in the CAD drawings above).

But yes, it's the electronics which are the hard parts.

I rather spend the money on implementing the 6T75's AWD option instead as there are some serious weight distribution issues with these cars. Also, it'd be cheaper too.

I am nearing the finish line on my LS4/F40 swap:

Custom Flywheel (with cad prints):



10" clutch/pressure plate:



Bolt on Starter Bracket to keep the LS4 starter:


All done but finishing up the wiring harness:

Of course AWD would be awesome but wouldn't it be just as or more difficult than just a straight RWD setup? Also what are you refering to by the "weight distribution"? I don't think adding a little weight to the rear will affect much.

At fieroguru.... Drool!
Are you planing on making a kit for the other fiero guys? (tuning aside)

The way the W-body is setup, as with most FWD setups, the engine sits on or forward of the front wheels. This isn't very ideal in a RWD situation where a near 50/50 (front/rear) weight ratio is desired along with steering rack location et al. Do note that the GXP has a ~65/35 ratio.

Converting to RWD doesn't do much for this.

With money not being much an issue:

For traction purposes, AWD. For RWD "effectiveness" and feel, new car.

Our cars are not even worth expending the mental energy required to speculate on this. I know that this makes me "buzzkillington" but maybe we can collectively work on attainable goals like, stopping the ******* headliner from vibrating...

gxp-miller-gxp

hhahahahahhahahhaha ^^^^^ love it! i completely agree!

WhiteGXP313

Haha I agree with Texas That **** gets annoying

gxp-miller-gxp

open up the headliner, i had a small 3inch in diameter, plastic circle that was just in there bouncing around . once i opened the back of the headliner it just fell out and the noise is now gone lol

texasGXP08

Thanks, I plan on getting around to that this week. I knew it got bad when I contemplated driving the car into an overpass pillar the next time it happened.

the reason this all stopped is because they couldnt get the computer code written. There was 1000s of lines of code and when they went to programmers they wanted way too much money to write the code. So they stopped working on it.

That's a shame, would have been very cool to see happen...

I don't know where you got your information from, lol.

The swap is on hold. We are waiting on PCS or someone with an E67 wanting to try out what TrueBlueGTO suggested.

So anyone in New Jersey, step right up.

E67 as in from say my 08 GXP? Im in... What do i have to do... As im sick in tired of the trans in my car.
