Question for Arnie & Roger I guess, how difficult would it be to fit a 4L80E to a Monaro? I know the loom needs to be changed to factor in the electronics but I have seen some advertised as full manual control.

Just curious as mine is in bits and needs a new clutch before it goes back together. Let's face it, the worst part about Monaro ownership is changing gear and I think an auto would be a nice enhancement:

Dont forget you old clutch wont be going back in, that will make a whole world of difference. The Shifter isn't ideal either, its pretty heavy too. Maybe change that, or if memory serves its adjustable, so we might be able to make it lighter.


It was pretty horrible before so look forward to something better. I guess the auto conversion is not that cost effective but if the manual can be nice to drive, I will persevere.

Mine's 3.622" stock stroke, fully built and probably 750hp. Old clutch was twin plate Spec (I think) used to drag horribly. Going for ls9 clutch now I think.

I'll hand you your arse down the mile if you like?

Cheers guys, something to think about but sounds like I'm better off just sticking with the manual box and coughing up for a decent clutch. The LS9 feels like stock and, because it was developed by GM just works. It will take a bit of fiddling to make the flywheel fit my 8 bolt crank but Roger sounds confident.

Engine is built and going on the dyno soon and it will be mapped with the aquamist system when the engine is back in the car. Hopefully back for Christmas.

Positive recommendation for ACT here


Act don't seem to do a kit for the 8 bolt flywheel unique to the LSA. However, Ligenfelter do: www.lingenfelter.com/mm5/merchant.mvc?Screen=PROD&Store_Code=LPE&Product_Code=L360066509&Category_Code=

Also, they do an upgraded ZR1 clutch to go with it: www.lingenfelter.com/mm5/merchant.mvc?Screen=PROD&Store_Code=LPE&Product_Code=L360050309&Category_Code=C328

Looks like this is the way I will have to go.

What crank are you using ?

If you opt for the LS9 clutch you will need the spacer otherwise it isnt going to fit inside your bellhousing. And this is assuming the factory flywheel is the same offset as the flywheel used in their conversions.
Talk to them to make sure you get all the right parts.


It's a forged LSA crank (in a forged LSA engine). Options are limited but LPE do have a solution it seems, Roger is aware of the bell housing issue and knows what to do. ACT don't do an 8 bolt option it seems.
