      I purchase a transmission from monster transmission in **********, ******* I paid $2500 order number ******. When I receive the transmission I had my mechanic put it in my vehicle and was told the transmission was junk. I had a warranty.I tried several times with no success to return the transmission I followed all their protocol on what they needed and pulled out all the forms. Now its been three weeks and every time I email them or phone them there is no response I am still waiting for this transmission to be picked up. Would appreciate any help. Thank you

      We bought a drivetrain solution (engine, transmission, electronic fuel injection) from Monster Transmission for a client project. We installed these items, and found that the engine had an overheating problem. We called Monster and they advised us we had to fill out a warranty form, which we did, to engage with their technical support team. They will not allow us to speak with their technical support team. The only way to engage with them is through a customer service intermediary. The result of this is, just to perform the tests they asked us to test to help troubleshoot, took more than a week. Once we ran the tests and supplied them with the information back, they have been radio silent. We have a defective product and an unhappy customer, and no means to engage with them on a timely basis to find a solution. This company should be put out of business. They make inaccurate claims about the quality of their customer support on their website. They go so far as to have customers of theirs say this while you are on hold on a recorded message. And it's clear from the number of other complaints you have received that they are the farthest thing from customer friendly. It's ridiculous. If we behaved the way they do when they have an issue, we would be out of business. All I want here is a functioning engine that is covered by their warranty and it's absolutely impossible to get them to help/engage.

      I purchased a transmission from monster transmission about a year ago after see they had good reviews. Or I though so until reading the problems everyone has on BBB site. I got the transmission back and install everything per monsters instruction. After install transmission had an issue. Reach out and filled a warranty claim. A tech reach out advised to change fluid so I did so and it some what solved the problem. I did not drive the truck much so it seems to fix it at the time. Well now the transmission is un drivable and monster told me to pull it out get it ready to ship back for warranty and to contact them once its ready. Well its ready and they WILL NOT ANSWER MY PHONE CALLS OR EMAILS!!! The absolute worse service.i call now and its like they send me straight to voice mail. They will not return my call or emails. Because of them I now have a lot more money invested in a truck that does NOT MOVE because I have a c*** transmission and monster will not call back To honor the warranty.

      Their website has videos on the product page stating they ship the transmissions for free. I tried to purchase and there was a hefty shipping charge. I called, spoke with ******* and asked and he said that isnt accurate, they only offer free shipping for some products. I said that it shows on that page that it has free shipping and he hung up on me.

      On 04/19/2024 I placed an order for one of their 4L65e 500hp drop in packages with converter and fluid. I am a first responder and I use my truck when called on. I have been without my truck since before the date of purchase. I have sent emails regarding the status. Some woman they call the transmission fairy has barely communicated. And claims I should have had emails as the steps go along. I got none of them even checking my spam mail, none. On 06/03/2024 I call to request a status and most likely a refund. The *************** up on me. As I was calling back I was getting sent straight to voicemail on any option you select to go to. I reach out to transmission fairy and said I request a refund. All of the sudden the ** has flagged her down and said my transmission ships tomorrow which throws many red flags as the trust of the craftsmanship of the rebuild of the transmission. How all the sudden after the word refund comes out the transmission has suddenly appeared. I was told refund process could take up to 30 days if approved. It is completely wrong how this company is operating to the public people. There has been absolutely no communication from the company, none from the sales rep of the company the whole time between 04/19-06/03 and what communication there has been is pathetic at best. First time experience is definitely turning into a final with a word of mouth about the company to future buyers to be aware of the problems I and many others are currently experiencing. You can take my money off a debt card that fast but you need 30 days to refund it sounds about as untrustworthy as it gets.

      Customer purchased and received an ***** on 1/22/2024. He reached out to us on
      5/28/24 regarding a missing ***. We did offer to cover the invoice for the *** if the
      customer provided the invoice to us. This order is currently in the warranty process.

      Customer purchased and received an A618 / *************************** through us. The
      original transmission left our shop on 4/16/21. Warranty issues arose on 11/3/21.
      A member of our team spoke with the customer on 11/17/21, letting him know the cost
      for sending the unit in under warranty, as well as speaking to the customer about
      potential upgrades to his Torque Converter and our White ***** Warranty package.
      The customer understood and there was no further correspondence until 12/3/21
      when we attempted to contact the customer for a follow-up on getting his
      transmission in to look at. We did get the customers unit in and did provide him with a
      warranty unit.
      On 3/19/24 the customer called in stating he was having issues with the warranty
      transmission provided to him. Despite it being over 2 years since the original order,
      and the customers second warranty, we have honored that and are in the process of
      working the customers warranty claim now.
