Have a look through his build thread, I think he’s got a Craig’s Automatics one if I remember correctly.

Thanks, BTW, how is your tranny from Hasty going?

Rebuild or changeover ? What did you have done to it ? Cost ?

It’s the original box with a rebuild done by the previous owner. I think Luke said it would have been 6-7K with the converter. Since I owned it I had the following done a couple of years ago. Can’t recall the cost for that but I do have the receipt somewhere here.

An easy mod. 6L90 pan plus filter.
Pan 24297102
Gasket: 24226850
Filter w/ seal: 24258269 (Extended neck. Cannot use 6L80 filter!!!)

Also another easy cheap(ish) mod is to buy the 6L90 converter (twin disc) and have it cut open and re-stalled to 2800rpm. It'll wake the car up without being overboard plus will handle WOT lockup on a typical LS3 cam header bolt on build for yonks.
Converter: 24045127 (Requires 6 x new holes drilled into flex plate, machine shop job)
O-ring: 24219390

And while I'm at it, chuck in this: https://transgo.com/product-details/6l80towpro/

Sorry to resurect an old thread, but did you end up doing a rebuild on your 6L80 VF Sleeper?

Yes. I had the trans rebuilt by Craig's. It was the 800hp build.

I did have an issue at the drags some months ago. It turned out to be a broken sprag clutch. Craig's did me right a fixed it under warranty. More info on my build thread here. https://forums.justcommodores.com.au/threads/vf-sleeper.292416/post-3372564

I still need to take it back for a little touch up trans tune.
