Always a pleasure doing business with monster from easy to use app to extremely good customer service

Transmission came in perfectly packaged, box was perfect, and it shifts better than new, extremely pleased with this unit, and not much more than OEM, but better internals. Worth every penny!

Was a breeze to get and great service to talk to.

We are very pleased with our purchase. Everything was done in a timely manner and we were notified in a very timely manner. The quality of communication was on point and we couldn't be happier

I made my choice to buy because by comparison this kit offered more for the price than other companies, I’ve only built three units over the years so I am really into research for this build because it’s going behind a mild build so I’m making several upgrades.
I called before ordering and the staff was very helpful answering my questions, shipping was as promised.

From the time I inquired about the transmission to the time I purchased and received it the customer service was outstanding. Made the whole process easy.

No room for bs at monster transmission, quick service, actual representatives to take your questions and orders.

I had to call customer service to order my transmission. My year was not an option on the website. The customer service representative did everything with my VIN number. All I had to do is purchase right from my email.
The process was so simple and fast.
Highly recommend calling if you have any questions at all.

Great company to work with, no automated bs great prices fast shipping.

Purchase,shipping,customer service responsiveness to my questions about warranty all exceptional!

I bought this E40D after I had the original trans in the truck blow up from too much power, the first impression was interesting as I put it in the truck and 40 miles later the front seal blew out. I contacted customer service and got a new trans sent out asap. They were very upfront and willing to help. Second trans is in and working amazing, great service by monster.

Monster transmission is an easy to work with company, everything went smooth and was on time, and i am happy with my decision on where to purchase from! Highly recommend the upgrade if needed!

I experienced a very smooth transaction, the transmission was delivered quickly without damage. The core return process was very simple. If needed I'd do business with Monster again without a doute.

My truck is shifting smooth and gas mileage is good

Torque converter worked good for daily driving

Factory 10r80 had all of the problems that Ford left us with. B&D transmission fixed everything better than new!

Why wouldn't you get the fluid provided by the guys who built your trans?they have it all!

I ordered a torque converter for my TH2004R along with a rebuild kit - I spent over $1100 with Monster. A few months later when I went to install it in my project car I discovered they had sent me the wrong TC for a TH700-R4 (30 spline instead of 27). I called them and since it had been over 30 days there was nothing they would do for me (zero)! Very poor customer service! I will NOT be doing anymore business with Monster Transmission. Obviously my fault for not checking my parts when they arrived, but I would have expected since it was their error they would have worked with me. Dissatisfied customer - Greg from Michigan.

I had to replace my transmission and put a monster in the truck I tow a 21 foot bass boat tournament loaded. it pulls much better with better shifting i have noticed slightly better mpg as well.
The service i received from ordering to delivery was great. i would consider a monster transmission a upgrade and not a replacement.

These guys are awesome.ordered and shipped in a few days.came in a crate,easy to send the core back.monster transmission is the best!

I am totally happy with my order the person on the phone was awesome and it was delivered fast with notifications the whole way here awesome job thanks

Got my converter and rebuild kit. Great quality but the best feature was the customer Service. Taking time to verify fitment and power capabilities was really nice.

This transmission is awesome I absolutely love it for my truck I pull my 30 ft travel trailer and it pulls it with with no hesitation over all a great fit for my truck

Just got it installed in the car behind my first Gen. 1955 Chrysler HEMI. It will be a while before I can try it out. So far so good.

Easy to order. Shipped fast. Easy to follow instructions.
