Blueprinted 2000+ Horsepower capable Rollerized Turbo 400 w/ Coan 1+2 Transbrake.
This has a New half aluminum/half billet steel BTE 36 element sprag Direct Drum, Coan 300M Main shaft
and a New Sonnax HD Lightweight Billet Steel Forward drum with their solid 300M input shaft.
Its a 7-7-5 Clutch setup. HD Straight Cut Factory Planetary Gears. Ratio: 2.48, 1.48, 1 to 1.
It was machined by me to fit 6 more RollerBearings in this unit. Not just the factory 3.
YES, 9 Rollerbearings. Even the Pump and Centersupport have them installed.
Comes with a Deep Thick Aluminum pan and Stainless steel ATI high flow filter.
There is $7000.00+ just in Parts cost alone. I can provide the cost sheet on request.
Try and get all of what's inside this unit from anyone else for this Great price.
The Output assembly is a HD factory Straight Cut gears assembly that are in Excellent condition.
There is a New Coan 300M heat treated main shaft installed in the output assembly. Super Strong.
The output shaft is the good solid one. You can use the Long or short driveshaft yoke with it.
The NEW HD aluminum Tailhousing with a new Bushing and Seal. All Rollerbearings are Brand New too.
The case, pump and centersupport passages were ported for better fluid flow.
The back half of the pump was fitted with a new Sonnax hardened stator support shaft.
Then the Pump surfaces were machined true to the new shaft. Perfectly Straight.
The pumps front half is a BRAND New GM pump half. Yes, Brand new Factory GM with a new GM hardened gear set.
New Sonnax Teflon coated pump bushing and new "GM AC/Delco" front oil seal. Those are the Best front seal.
New Coan adjustable high pressure pump spring was installed for 2000+ HP and great hold. Should produce +-210 psi.
The back of the pump has a rollerbearing installed, New lower stator bushing and Special alloy sealing rings.
The New Sonnax HD Billet steel input hub comes with 2 bearing that go between the direct drum and forward drum.
There is another large rollerbearing behind the Direct drum on the centersupport. This takes the front half
friction load off the planataries and then controls front endplay from the centersupport to the Pump. Frees up horsepower.
Won't effect rear endplay clearance at all. Takes the load off the back half of the transmission. Great trick.
The reaction carrier was lightened and machined for a large rollerbearing between it and the output carrier.
New BW Low roller clutch in the reaction carrier and a New TCI Kevlar rear band.
The the new SFI Case comes with its own rollerbearing in the back. That's a total of 9 bearings inside this unit.
All bearings and gears are pre-lubed before assembly with TCI Transmission Fluid.
The Billet steel Center support came with a new bronze bushing. And its port matched to the case for quicker
direct clutch release. It was also machined and fitted with a ATI bronze stablizer bushing to keep the Direct
drum from any wobbling. So with the ATI Bronze stabilizer bushing and CS rollerbearing, It WILL spin perfectly TRUE.
Coan HD rear accumulator return spring installed for a Quick release Transbrake operation.
Both clutch drum pistons are New Coan Billet aluminum and machined flat for better clutch
apply and to set clearances. The Centersupport has a new 10% Oversized Billet aluminum piston in it.
5 New BTE intermediate Clutches and Steels. Came with the Direct Drum.
All Apply sealing rings are the Special steel alloy rings I use in all my units now. Seals Great for Pressures.
All new clutch lip seals, gaskets, o-rings and seals.
The New BTE Direct drum is a 36 Element sprag half aluminum, Half billet steel (sprag and sealing ring area)drum.
I use Raybestos Red radial grooved clutches with 7 clutches and 7 Kolene steels in the direct.
I added a new Coan Billet Steel Pressure plate instead of the factory cast iron one.
The direct drum has a .062 hole drilled for transbrake operation and has the Coan HD Springs installed.
The 7 direct clutch pack clearance is set for a Transbrake using my 40 years of experience.
I also used the new Sonnax HD retainer plates on both Forward and Direct drums too.
The forward drum is a Sonnax HD Lightweight Billet steel unit that has a 300M shaft.
It has 7 Alto HP Clutches and 7 Kolene steels. Very Nice forward drum with fill spacer.
BTE 5 clutch Intermediate clutch pack (2nd gear) and a Billet steel intermediate pressure plate.
New Coan 1+2 Reverse pattern Aluminum Pro-Tree Transbrake valvebody installed.
ATI Stainless steel screen high flow filter with factory deep pan pickup tube with 2 o-rings installed.
New Thick Deep aluminum pan installed. Comes with 6an steel line fittings.
Gears were pre-lubed before assembly and the clutches and band were soaked 2 days. (not 30 mins).
Clutch packs were air checked for assembly and operation. The Kevlar rear band was also air
checked for operation. All bolts have been torqued to specs.
Thanks for looking.
