Mega Monster Transmissions
Engineered to Dominate, the 4L60E 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 500 horsepower(450 torque) with a naturally aspirated system using pump gasoline. Equipped with a Reprogrammed Automatic valve body, most units allow you to 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!".

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 thoroughly inspected, blue printed and quality checked to ensure that your investment is completely flawless. For the system to operate properly, ECM computer code(s) must be cleared prior to initial drive of the replacement transmission. We recommend using a Snapon-OTC or Dealer scanner for this procedure.

The 4L60E has a 3.06 ratio in first gear, which is 20% lower than most transmissions. The 30% overdrive will give a 30 to 40% increase in gas mileage on the road when compared to a 3-speed automatic transmission.

*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing extension-housing and speedometer gear. This Monster 700R4 Transmission does not come equipped with a new Speedometer Gear. Certain vehicle specific extension-housings may not be available with this unit. In most cases, you will be required to swap your original extension-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 extension-housing will need to be reused.





I''d like to thank everyone at Monster Transmission and I would reccomend them to anyone
I just purchased a 4L60E 4WD transmission. It''s going in my 1997 Tahoe. After a lot of miles on a stock transmission and all of the modifications to my truck, I wanted to go with a stronger performance transmission. They allowed me to customize my heavy duty transmission package with some heavy duty parts and a deep pan to keep it running cool. It has a 3 year warranty which is the best on the market. Plus Monster has free shipping, which is great. It comes professionally paletted and they have great customer service. They answered all my questions. I''d like to thank everyone at Monster Transmission and I would reccomend them to anyone who is looking for a top of the line transmission. They gave me a great deal. Thank you.

Good solid transmission. Shifts firm and solid with no jerk or slack. Never misses. I have about 800 miles on it now and so far I'm happy. Shipping company because of my location was a pain to deal with but that isn't on monster. They can be hard to get a call or email back from but not to bad.

I bought a transmission for a 1990 Chevy 4x4 pick up and it came just as it was promised. Everything was in good shape. Monster Transmission did a wonderful job in following through with everything perfectly. After it was installed, it is working perfectly, and we are very thankful for the transmission. Again, Monster Transmission has done a wonderful job, and I would recommend them to anybody. Thank you.

I''m really happy with it. It shifts like a racecar and pulls like a mule.
I ordered a Monster Transmission for my Chevy van with a 350 motor in it about a year ago and I''m really happy with it. It shifts like a racecar and pulls like a mule. It''s a fantastic transmission and I''m going to order another one for another type of vehicle. Thank you very much. I''ll be ordering a new one.
