I placed an order on a Monday morning around 10am for a converter. By 1pm I had an email, text and phone call from the sales team to confirm my order details and ensure I was ordering and getting the correct one for my application.

I’ve been in the aftermarket automotive industry for 25+ years and this is by far the absolute best service I have ever received when ordering parts.

Will absolutely do business with Monster again.

Sales and Shipping are very knowledgeable and professional. They picked up my transmission rebuild it and shipped it back as it is original to my vehicle. I’m 100% satisfied and the transmission looks spectacular.

Trans just showed up and looks great , will update once installed . ETA of delivery was right on point

From ordering the transmission to monster scheduling the pick up of the core. Everything went great. Would recommend monster to anyone. I wont look anywhere else . Monster is our go to company

Got the transmission quicker so they said I would receive it instruction manual with what I needed was good information took me about nine hours to change transmission and transmission cooler shifts seem to be good so far

Great service Great shipping Great help from the company

Had ordered this transmission
Last week John V. Was very helpful received transmission same time and day as shipping company had told me it would arrive.
I was very pleased with the service and the shipping service.
Was told by the installer that it wouldn’t be here on time because apparently he’d never felt with you folks. I informed him he should start. He had said the other companies he’d felt with had never been on time and had received little to no support.
So hopfyjis will give you more business. Thanks and keep up the good work. It’s hard to find this day and time.
Have a nice day!

Great trans shifts good and monster was great to work with

After purchasing another competitors 4L65E at a reduced price and a similar advertised HP rating - I learned the hard way that not all builds are the same. It didn't even last 300 miles before 1st and 3rd gear left the chat. Once I received the the Sport Monster I could instantly tell the build quality was different. Deep pan - billet servo and billet torque converter. I was confident that the advertised parts were certainly inside the transmission as well. I installed the transmission, new trans cooler lines and a new remote stacked transmission cooler. Initial driving and the transmission shifts better and runs cooler (155deg on a hot day) I am assured that it can handle to power - plus the warranty gives me a peace of mind. I would highly recommend Monster Transmissions. The price is right, the support is great and the quality is above par. I used Monster to replace my stock 5.8l Bronco 4AOD transmission and that one has also held up exceptionally with daily driving and occasional off road adventures. Monster is a company I will definitely use again

Terry was super helpful in helping me place my order and ensureing that we had the correct information

Had a rocky start with the company being was told shipping dates were gonna be way sooner than what they were. Also thought trans was built already for shipping. Once we got through the misunderstanding with all that they made it right and got the trans shipped in a quick and efficient manner. The trans showed up crated. All there. Instructions were clear and understandable to a mechanic or to a normal back yard mechanic. Trans went in great no issues. Did relearn on trans. Took down all the data required for the warrantee. Ran it the 300 miles. Checked everything over. At 350 hooked onto the trailer and let it eat. Overall im super impressed with the drivability of this trans. Shifts firm. Doesn't get hot. Overall I think Monster did a great job.

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!
