Invest in a Monster Transmission and make your Opponent "EAT YOUR SHIFT!"

SS Mega Monster Transmissions
Engineered to Dominate, the 4L65E 4WD SS Mega Monster transmission is tough enough to withstand the rigors of even the toughest heavy duty trucks, used for towing/hauling or extreme off-roading & racing. It is ideal for vehicles powered by 4.8, 5.3, LS1, or 6.0L engines producing up to 650 horsepower 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 fully customizable racetrack shift that bangs through the gears giving you all the right to say "Eat My Shift!".

The SS 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 new transmission. We recommend using a Snapon-OTC or Dealer scanner for this procedure. This custom built transmission is highly recommended for any type of vehicles that have larger tires and are lifted.


*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing extension-housing and VSS (Vehicle Speed Sensor) for your new unit. This does not come equipped with a new VSS (Vehicle Speed Sensor). 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 VSS (Vehicle Speed Sensor) for your application or if you are unsure if your extension-housing will need to be reused.

The 4L65E 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.

Very pleased with this transmission, the Monster 4l60E SS. It shifts great. No leaks. No issues. It is a great compliment to my modified "5.3" in my '03 Z71 Suburban. Every part of the process from ordering through shipping my core back was easy. I was very pleased with the customer support from Monster and the shipping vendor. I would highly recommend Monster transmission products and services.

I use my Monster for Towing
I've got a 2006 GMC Yukon. 4WD. 5.3 liter. Put a Monster Transmission in it, just specifically for towing. Every time I towed my transmission would slip. And so after I put that in with the fluid that monster gave to me, everything's been going great. Its been about 2000 miles right now. And I've towed from BMW's to bigger things for my trailer being Acura MDX's and what not. And I mean, I haven't had any problems. No whining, no noises. I put the transmission in and when I put it in, it bolted up correctly. Everything had no problems. It's really nice knowing that they have the drain pans with the drain bolts in it so you can just drain out your fluid if you need to. I mean, everything was perfect. I couldn't be any more satisfied. Alright, thank you.

My experience with Monster Transmission has been everything I expected from a company like this after hearing them talk about it on a Sunday morning, Saturday and Sunday shows, the car shows you know I figured I needed a transmission and went to the place where I thought would do the right thing for me and the absolutely did, I put a new transmission in my 2004 Chevy Blazer and I wish I never had to but I did and it is totally worth it in the end, the car shifts fine and accelerates awesome and nothing short of amazing, thank you very much.

This is the best transmission that I have had put in my truck.
I bought the 4L60E for my 1996 chevrolet pickup. We live in Texas so we do a lot of towing and hauling out in the country. This is the best transmission that I have had put in my truck. I did do a bunch of rebuilds with the local dealers and nothing has seemed to work quite as well as the Monster Transmission that I ordered. The staff has been kind enough to help me out with another one for another pickup truck that I''m putting together. The first one has been working so well that I just decided to go ahead and stick with the best and order another one. The thing that I like the most about it is that either way, I''m going to spend about the same amount of money. Whether I have one pulled out and rebuilt and put back in or I do the labor and get a better product. For me, that''s the most important thing. I don''t mind doing a little bit of labor and if I''m going to get a superior product with a little bit of sweat equity put into it. For me, that''s the best bang for the buck. There is just no better for me and for what I do. I tow and I don''t even have to take it out of overdrive. I just haul it down the road and I don''t even have to worry about anything. If you''re thinking about which transmission to go with, I would highly recommend Monster Transmission. It''s the best one that I''ve had.

They actually took the time out for me to find the transmission that I needed for my Escalade
I got my 2004 Escalade brand new but it was completely stock. After I purchased it, I beat it up a little bit. That''s why I wanted a Monster Transmission. I heard excellent reviews, I read many forums, and that''s why I bought Monster Transmission for my Cadillac Escalade. Since my car is one of the best on the market and I think Monster Transmission is one of the best on the market, I put one and one together and that''s why I chose Monster. The sales team is one of the best that I have actually called. Finding the transmission was, to me, a little bit difficult. The sales team was very patient and understanding with me. They actually took the time out for me to find the transmission that I needed for my Escalade, how I drive it, and what fits my needs. Once I received the transmission, I did, in fact get a courtesy call, which I do appreciate. Most of the companies on the market, after your purchase, really don''t care. But Monster Transmission does care and that''s very encouraging. To judge the performance part, I would guess that you have to have it yourself. But the best ways to explain Monster Transmission is powerful timing that''s right on the button. I couldn''t ask for anything more. What the sales team explained I did receive. I definitely wouldn''t choose any other transmission company out there. If I decide to get any other truck or car or let my friends and family know about any of the transmissions out in the market, I would definitely, ABSOLUTELY let them know about Monster Transmission. Not only did I do my research on Monster Transmission, but one of the main reasons that I decided to buy a fabulous transmission was because of the warranty. Nothing on the market now gives you 3 years and unlimited miles. That doesn''t even make sense! 3 years and unlimited?! Nothing on the market is 3 years and unlimited but Monster Transmission does. You better believe it. That means I can drive from here to California, back to Jersey, back to California all day every day for the next 3 years. You can''t beat that. BEST ON THE MARKET. You have options. Conclusion: Cadillac is one of the best makers on the markets these days. Would I have bought any other transmission? No. Monster Transmission is definitely the way to do it. If you don''t want to keep spending money, and you want to buy it once and keep it for life, there is only one way to do it. That''s Monster Transmission. If you want to spend money and lose money with other market competitors, go for it. If you want to save a buck or 2 in your pocket, this is definitely the best buy for your buck.

They hooked me up with a 4L65E SS
I drive a 2003 Chevy Silverado with a 5.3L engine. I haven''t done anything crazy to the motor but I just recently blew my transmission so I called down to Monster. They hooked me up with a 4L65E SS with a 2500 stall and a cooling package. The craftsmanship is amazing! We were all surprised on how well the product looked. We were afraid to put it in because it looked so good! It shifts great through every gear. There is nothing bad about it. It is all around amazing quality that they have done.
