Hello friends I had a customer come in with auto issues in his nice XC sedan.
End result I rebuilt the auto to handle 600hp with my custom STG 2 valve body, also I installed the new billet dual alloy pan where I’m installing the new AFD flexi dipstick on the passenger side.
Awesome setup👍🏻👍🏻

Just finished a turbo 400 going behind a 1200hp LS MTR in a VN Commodore.
I used a heavy duty truck auto core, it’s double thickness in the casing making it a lot more rigid.
Vasco input shaft, COAN main shaft all rated at 2000hp, pro mod drum, SONNAX rollerised forward hub, REV pattern billet transbrake V/Body.
I will send it off to get dynoed next to make sure all the pressure readings are to my satisfaction.
Happy days!

Hello guys,
I have a Hg come in with a powerglide auto leaking oil, upon removal I discovered the main case was cracked.
I tell my customer these OE Cases are 51 years old now they weren’t designed for 250psi pressure and transbrake, a lot of stress on the case.
I give the option of another standard case but no warranty if it cracks again or you go for the billet case last forever. I ended up rebuilding the unit with a Reid case.

Hello friends, I have a customer with a Chrysler charger 265 engine making 350 hp the standard BW 35 trans wouldn’t last in a heartbeat.

So I came up with a combination, supplying a recondition C9 26 Spine Auto with custom stage 2 shift kit. I have made up a special adaptor to utilize the factory BW Bell housing.

Ok, friends I have rebuilt a 4L80E trans, it comes as a Full Manual Forward Pattern also a lockup function which comes on only in overdrive with a toggle switch command.

Auto is rated for 800hp, going into a HG sedan. This package will make the vehicle economical on the Highway and very robust down low because it’s got the running internals of a TH400.

VERY POPULAR COMBO.
