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 for your new unit. This Monster TH350 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.


I've ordered a Monster Transmission for my chevelle back in 2010 and it is now January 2015 and the transmission has been awesome. It's worked flawlessly. I love it very much. So if you are looking to buy another transmission. This is the one to buy from Monster. They are the greatest and they are really good tech people too. And they're always helpful.

I dealt with Danielle today. Had a problem with my transmission pan, I ordered one with a drain plug, it had a leak. They told me how to fix it. We agreed to have the exchange, I would rather have a regular pan. So just in case there were any problems I wouldn’t have to worry about it in the future. They were very good about it, I sent my pan back and they sent me the pan without the plug. Very good customer service, Appreciate it very much. I always appreciate good customer service, because when you’re dealing long distance especially with expensive stuff, and this car is very important to me. This car is going to go on a TV show. It’s a ’68 Camaro, It means a lot to me. So I hope that everybody knows that you guys are giving quality service. Thank you very much.

This was for a turbo 350 automatic, I just wanted to say how good my transmission is, I have it in the car running, installed it without a problem came with all the instructions, really appreciate all the calls back to me checking to make sure everything was ok with the transmission and all, I think that is really outstanding that you do something like that and once again I am extremely happy with it, so much so that I just got off the line and purchased a 700 for another project of mine, I just wanted to say thank you and keep up the good work.

love the company
I got ''84 Chevy with 12" of lift and a 383 Stroker with a Monster Transmission Turbo 350. I''m now ordering a 700R4 because I want the overdrive. Great Transmission, love the company. I actually went up there and picked up my transmission from you guys directly, before. You guys are big help. Already, Thank you.

They are pros at what they do
This company just has it together. That''s all there is to it. They are pros at what they do. If you look into their website and you look into what they do, they do an actual real world test dyno on all of their transmissions. There''s a huge difference in the inside parts of a transmission. I sold parts for 6 and a half years. I was certified in parts with OReilly''s auto parts back in the 1990s. There is a huge difference between metals and fibers and seals and things that go inside of a transmission. These guys just use A+ top of the line parts in all of their units. You can tell by the performance. This thing is just the smoothest transmission I have ever put in in my life. Thank you so much Monster Transmission. I am looking forward to doing business with you guys again in the future. Thanks so much.
Verified Buyer: 
The transmission itself is A1 top shelf.
The technical support system, the staff, and in particular, the transmission itself is A1 top shelf. We don''t have it in yet but I have no reason to doubt the capabilities of this machinery. I look forward to hearing from Monster Transmission as soon as possible so I can order some more parts. Thank you.
Verified Buyer: 
I will be contacting you for another one. Thank you!
I purchased a transmission several years ago and put it in a Trans Am and I have had very good luck. It services well and the vehicle has enough power so that it''s time to replace it and I feel good about putting another one in there, so I will be contacting you for another one. Thank you!
Verified Buyer: 
You guys are the greatest!
I purchased a 350 Turbo for my 1970 Chevelle. I restoring it and putting a 350 turbo engine in it. It''s a great transmission. I love the way it performs. You guys are the greatest!

I am so happy with the service I received.
I am so happy with the service I received. They were very helpful and gave me all of the info that I needed. I got the transmission in and the car runs better than it ever has. It is truly a dream to drive right now. The RPMS runs nice and low. I have a 1972 Camaro with 410 gears in it and since putting this transmission in 2 days ago, this is the happiest I''ve been with the car since I''ve owned it. I can''t say enough about Monster Transmission and the service I received so far. Thanks a lot, keep up the good work, and I will refer everybody I know looking for a transmission to you guys.
