4L80E Transmission - Level 3
|
|
|
|
"
"
The baddest of the bad, this is a non-electronic 4L80E transmission. Some of the features are: Full manual shifts - the transmission will be in the gear you select and changes to any gear you choose when you move the selector, no computer or wiring needed, Red Eagle clutches, Carbon fiber band, RedEagle PowerPacks for the forward, intermediate and direct clutches, Kolene steels, Blue Plate Special clutches for the overdrive and overrun clutch sets. The 16 element intermediate sprag is replaced with a 34 element sprag, rated up to 1200 horse power depending on upgrades and has full throttle 3-4 up-shifts. It comes with a non-lock-up torque converter (#L80-NLU) and the core charge is included in the price. This is the transmission that off-roaders, big horse power streeters and racers have been waiting for. Something with an overdrive gear that you can beat the snot out of without giving it or you a runny nose. It just gets comfortable at 900 horse power. The shift kit alone costs us $250.00 and takes a full day to install. All of this can be yours for $3295.00. Every Quadzilla transmission is tested in our test truck. It doesn't get any better than this folks. If you have over 500 horse power you may want to consider this transmission. Add $150.00 for LS1 type bell housing bolt pattern (7 bolt). The late model type are built from 1997 to 2001 cores, known to be the best.
Can be ordered with a 11 inch torque converter rated at 1200 horse power for an extra $529.00 (#6XX). Gear ratios, 1st 2.48, 2nd 1.48, 3rd 1 to1, 4th .75 . In other words when in 4th gear a 4.11 rear end ratio would be equal to a 3.08 rear end ratio. Can be ordered with a 2.75 1st gear ratio and a 1.57 2nd gear ratio for an extra $650.00 (John Kilgore). Can be ordered with a deep cast aluminum pan for an extra $212.00. Order the hardened input shaft if you have nitrous ($449.00). It comes with a speed sensor for an electronic speedometer and can be equipped with a speedometer control unit to control a speedometer cable (#68 below). We now have a tail housing available for a gear driven speedometer cable, see below. The 1997 up 4L80E transmission can be used on the new Chevy 572 cubic inch motor, because both have 7 bell housing bolts. The freight runs from free to $165.00 after freight discount in most cases. The prices includes the core charge, but if you want to return your core for a core refund of $300.00 to $450.00 depending on year and model less freight, just let us know.

2-27-2004.
The Performance Automotive and Transmission Center Quadzilla
transmission has been selected for the Dobbertin HydroCar project. This
is the awesome Chevy 572 cubic inch,
750
horse power, 705
torque motor
that will deliver the power to the PATC Quadzilla transmission. This was
the combination needed to make the Dobbertin HydroCar the worlds fastest
amphibious vehicle. The 4L80E Quadzilla is one of the few transmissions
in the world up to this challenge.
5-7-2004.
PATC has a Quadzilla transmission in the up-coming Las Vegas to Reno 500
mile road race. This transmission will be in a Hummer H1 powered be a
Chevy 572 cubic inch big block.
2-10-2005.
PATC has a Quadzilla transmission in a 1992 Hummer H1 that will be in
the 3-6-2005 Morocco-Rally (Tuareg Rally). Later this year it will be in
rallies in Libya and Tunisia. This sounds like the ultimate test. |

This transmission has automatic shifts and a heavy duty / performance lock-up torque converter (#L80-LU). Starting with one of the strongest transmissions on the planet we add a Transgo stage two shift kit, Red Eagle clutches, RedEagle PowerPacks for the forward, intermediate and direct clutchs, Kolene steels, Blue Plate Special clutches for the overdrive and overrun clutch sets. It has a Carbon fiber band and the 16 element intermediate sprag is replaced with a 34 element sprag. Rated up to 1000 horse power depending on upgrades.

| Stock Plus 4L80E Transmission - Level One + |
This transmission has automatic shifts and a heavy duty lock-up torque converter. Starting with one of the strongest transmissions on the planet we added a Transgo stage two shift kit. Rated up to 700 horse power with the Red clutch and torque converter upgrade. Every level one stock plus transmission is tested in our test truck. Now you can afford a pre-tested 4L80E transmission for only $2149.00. As an added bonus you can receive a $100.00 discount on a Compushift Electronic Control Module if you buy this package deal. This would bring the total price of the test driven 4L80E transmission, torque converter and electronic control module to $3248.00. This transmission will take the place of a 4L60E transmission with the use of #10X below (LS1 type computer only). For years now people have been looking for a way to replace the weaker 4L60E transmission with the stronger 4L80E transmission, well the time has come.
You can upgrade to all 5 sets of Red clutches for $159.00 making this a very strong transmission. If you have over 400 horse power you need the #L80-LU torque converter upgrade for $159.00. The freight will run from $110.00 to $175.00 in the lower 48 states. There is a core charge of $450.00 on 1996 back transmissions or $600.00 on 1997 up transmissions if you don't have a trade-in. If you have a trade-in simply call us when it's ready to be picked up for a core refund less the freight to get it back here. Trade-ins must be in re-buildable condition and of the same type when we receive them.

This is the HydroCar Quadzilla transmission with the custom built transfer case mounted on the tail. The Atlas transfer case is an all-gear driven unit that will easily handle the horsepower and torque of the 572 cubic inch Chevy engine. It was custom made as a right-hand unit and can be shifted for the front wheels only, the prop only, or both together, during launches and landings.

#2V. Common problems in vehicles with a 4L80-E transmission include uncontrollable line rise (upwards of 500 psi), high line pressure in reverse, broken direct clutch drums and/or broken cases. These problems can be caused by excessive EPC torque signal pressure. The Sonnax self-regulating reverse boost valve eliminates these problems by limiting EPC pressure. The boost valve has an encapsulated relief valve that will allow EPC pressure to exhaust if it exceeds 95-105 psi. A closely toleranced sleeve is included with the kit. This restores the hydraulic integrity between the valve and sleeve, which can also cause the problems mentioned previously. O-rings have been added to the sleeve to compensate for pump bore wear and prevent pump scrappage. Cost $51.00 |

4L80E Actuator Feed Limit Valve Kit • Kit includes wear-resistant sleeve and anodized valve with annular grooves to prevent side loading. • Valve operates in full-contact sleeve, providing 54% more support. • Boosts oil pressure to the shift solenoids. • Eliminates AFL oil loss, corrects low line pressure. |
|
|
|
#2AV. The 4L80E OEM actuator feed limit (AFL) valve has a large reaction area and is greatly affected by side loading, which wears the valve body bore. The EPC solenoid oscillates the torque signal and AFL oil, which increases valve action. As bore wear increases, oil pressure is reduced to the shift solenoids, which causes solenoid and ratio codes. The same AFL oil loss results in lower line pressure. Valve Cost $49.00, Tool Cost $185.00 |
