Mega Monster Transmissions
Engineered to Dominate, the Turbo 350 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 400 horsepower with a non-supercharged system 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. 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 Turbo 350 is a 3-speed automatic transmission.

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. This 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.

I bought a rebuild kit for a turbo 350 from Monster Transmission and it's awesome. I love the way it shifts and it really made a difference in my transmission.

I've got a 1986 s10 Blazer, which I bought a 350 Turbo for back in 2011 from Monster. We started off on a bad foot, the cork gasket they used for the pan leaked. We went and got a new pan gasket for it and now its working fine. It's been working fine now. It shifts really hard and we are happy with it. I'm about to purchase a 400 Turbo for a full sized Chevy pickup I've got now. Its a 1974 with a 496 big block. We're hoping that It'll shift as good or better than the 350. They say the 400's are stronger, so. My truck weighs quite a bit heavier then the s10. but, I'm really pleased with the way it shifts. A real positive hard shift. It doesn't bang like it's breaking something, it's just a really nice shift on the Monster. So, happy with that. Like I said, had kind of a cheap gasket, but they said that a lot of people change the pans and run their own gasket. It was kind of a pain in the butt. Like I said it was worth it. I'm happy with Monster Transmission.

She''s running real good. Monster will hook you up!
I just got my new Monster Transmission and it''s real nice looking. The paint job is really nice. It looks like an automotive paint job. The transmission has a lot of good stuff in it. They put in extra bands and clutches. It can handle a lot of horsepower and they built it to my specifications. All I did was give them a call and told them what horsepower rating and torque I''m putting out. I gave them the make and model of my vehicle and they built it and sent it out to me free of charge. For what I spent for this model, I couldn''t have bought it from one of the local parts stores and got a transmission this nicely built or nice looking. It going in my 1974 Chevy pickup Silverado half ton 2WD. I''ve had the truck for about 15 years and I''ve done a lot of upgrades to it. I''m took the transmission to my local transmission installer to have them put it in for me. She''s running real good. Monster will hook you up!
