Mega Monster Transmissions
Engineered to Dominate, the 6L80E Mega Monster transmission is tough enough to withstand the rigors of even the toughest street machines delivering tire-spinning shifts race after race. It is ideal for vehicles powered by engines producing up to 550 horsepower using pump gasoline. Equipped with a Manual/Automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears giving you all the right to say "Eat My Shift!". When you use the manual gear selection feature, the Mega Monster upshifts and downshifts when you move the shift lever, please note, in order to have complete control of the RPM shift timing you must upgrade to a full manual valvebody. When you select the normal drive position, the transmission retains its firm, automatic shifts for the ease of driving you look for in an automatic transmission. The 6L80E is a Six speed rear-wheel-drive, electronically controlled, automatic overdrive transmission with torque converter clutch. Clutch-to-clutch architecture with integral electro/hydraulic control module.

The Mega Monster Transmission features: the latest technology in our industry with only the best internal components for increased strength, dependable performance and monster torque capacity. All Monster transmissions are custom made in the USA and quality checked to ensure your peace of mind. For the system to operate properly, all throttle linkage, vacuum lines and kick-down components must be connected and adjusted properly.

*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing tail-housing and speedometer gear for your new unit. This Monster 700R4 Transmission does not come equipped with a new Speedometer Gear. Certain vehicle specific tail-housings may not be available with this unit. In most cases, you will be required to swap your original tail-housing (this will NOT void your warranty). Please Contact Us to purchase a proper speedometer gear for your application or if you are unsure if your tail-housing will need to be reused.

Received the trans a couple of weeks ago in great condition and everything was included just as expected. Got all the little things hooked up and this weekend the tranny goes in. I want to plan a road trip to your shop and car show on tues in July to meet you all and give testimony on my new overdrive. Can't wait to get it on the road in overdrive.
