delivered in the time frame that was expected, no damage in shipping good create. this is the second trans i got from them, have no complaints

Called with some questions. My questions were answered with extensive knowledge and I placed my order on the spot.

The time in which I recieved it was quick and the little that ive used the truck hasn't been alot since the installation but it seems good quality and smooth shifting

Awesome job at building my transmission. Shifts great and very smooth. I'm very pleased with my purchase if I need anything in the future you bet I'm coming back to Monster...

Quick delivery and the part fit as it should i haven't test driven it yet but looks to be very well built and quality of the work is 100 percent.

Our experience with this company was excellent. The transition was smooth and easy from start to finish. They even took the time to call and confirm that we had everything we needed, including verifying our VIN and other details. We also appreciate that they offer multiple payment options — a must for us. Overall, their professionalism and attention to detail made the entire process stress-free and efficient. Highly recommended!

I have a 1967 chevelle with a LS6 Crate 454 backed up with Monster Turbo 400 . It shifts very solid, whether manually shifted or automatically. I strongly reccommend!

Everthing was exactly as expected and works amazing, super easy and amazing customer service

Great service. got transmission quickly. Was always there to answer questions.

Best transmission fluid money can buy

Sales people were very patient and helpful

We ordered the transmission on a Tuesday expecting 3-4 weeks for build and delivery. We received the transmission in less than a week which was incredible! The upgraded drum and valve body is an awesome touch to keep this truck on the road for many years to come. We will be using Monster for all of our truck transmissions from here on out!

The whole process was flawless and I can now drive and tow with peace of mind that I have a well built transmission to get me where I need to go.

Just installed it, shift good and firm, will update at 100 miles and when cam in installed. Good install guide too, new cooler added and good temps and flow. Wish i couldve kept lockout on the TC but i plan on swapping TC anyways 🤠

We just bought a new transmission for our truck. We followed the website link to start the core return. Everyone emailed us timely and the core return prep and bill of lading instructions were simple and easy to follow. Fedex freight did a great job at communicating with us to coordinate pick up as well. Making this fast and simple process for us.
