Monster Transmission & Performance Avis 

I saw these guys on TV. When I was looking for a company to rebuild a AODe Trans for me I gave them a call. Ordered the transmission, they said 2 weeks to get it. OK. Received the trans 1 month later. Got the transmission installed and could not get the shift points where they wanted them. Called them and got customer service. ( should I say the lacking of ) but they said they would have the tech or warranty dept get back to me. Well after calling and emailing for a month they finally got back to me. The tech said to try a couple things and let him know. Two weeks later I finally got a call back. After leaving 6 messages and and email. Well he told me that it had to come back to Monster and if they found it was error due to install I would have to pay otherwise they would cover shipping and everything. Well they must have found a problem because it was zero cost. I had stopped payment for the transmission after 3 weeks of not getting any response. When I received the Transmission back after almost 5 weeks we reinstalled. Shift points are now where they are supposed to be....But the firm shift that was quoted me is terrible. It slides into gear. Called them again. Now they sent me to collections because I stopped payment. This is just ridiculous. They won't answer or return calls but yet they say they want a long lasting relationship. My advise STAY CLEAR OF THIS COMPANY. I had to pay again to. have the transmission removed and reinstalled. NOT a good company to work with.

I called before I ordered a valve body and was told it was a manual reverse pattern valve body with trans brake. When it came it wasn't a trans brake valve body. I called and they were going to find what I needed but it was on national back order. After a month I called back and they will not refund my money now. I would not recommend this company to anyone.

I received the wrong Torque Converter for my truck. I wrote them a bunch of emails about it never got a response. I called them on a Friday they said they wouldn’t be able to help out until Monday or Tuesday because supervisor wasn’t there, so I told them if I could get help from anyone else she said it has a been a couple weeks already as it would be a problem seems as if they are trying to delayed the resolution until the return policy time limit had expired. This company has no customer service ethic.
Also Still waiting for a call back from them I never received. Save yourself a headache and money order from some where else

The buying process went pretty smoothly, but once it shipped they didn't seem to care anymore. I had questions right away after the install about how it didn't seem to engage properly and felt a bit off. Their only response was to send it back for a warranty check at my expense. Wasn't worth doing that so gave up and figured for a 25 year old truck it was all I was going to get. A year later and I find out the torque converter I got from them was probably defective and the source of the issues. Tried reaching out to find out if there was anything they could do but they won't respond. So another thousand plus dollars and hopefully now it will be fine. The transmission itself always seemed to work.

Failed transmission for F350, approximately 20k miles, no towing or heavy use. It took 3 months of phone calls and emails to get them to approve returning it for inspection, 3 more months to get the replacement. 2 additional months to get a check to sort of reimburse removal and replacement along with palleting it for shipping. They reimburse at a shop rate of 50 an hour, refused to reimburse for fluid (that I bought from them for the first transmission), refused to reimburse for flushing or anything else required to replace a defective transmission. This is the worst company ever. All told it took almost a hundred phone calls to get the check. Horrible product, worst customer service ever!! Not the people on the phone, the company approach that is ignore until the customer gives up!!! Never ever do business with this place

Do not trust this company, the sales department will tell you what you want to hear at time of sale and promise fast delivery. Customer support will welcome you, then ignore you . Lucus with built team will lie to you repeatedly. Order mine on Oct. 2nd, after weeks of being told it would ship next week. On Nov. 20th I had had enough BS and canceled my order. The CEO won't even respond to your emails.
Bad company from top to bottom. Don't waste your time.

this company is trash first transmission lasted less than 90 days the second didnt make it a full year had another shop rebuild it found that it was missing parts inside this is the 3rd time im rebuilding it

Purchased a transmission from these guys and It leaked badly. They required me to take it to a certified transmission shop for evaluation and repair. It cost me more than $500 to have there poor quality work fixed. I got a "reimbursement" check for $275.
Warranty is a joke. Don't do business with them unless you are willing to get screwed!

If I could give zero stars I would. Don't order from this company!! SCAM to say the least. Transmission lasted only a week, and they will not do anything about it except have us pay to send it back and pay for new parts that have to go in.

Brand new transmission failed now to do the warranty after sending pictures has taken weeks and weeks and weeks and I'm out the cost of new fluid and labor and I run a repair shop and there were several things that they forgot to do when they built this transmission.

This was the worst experience I’ve ever had involving getting parts, and any responses from one company.
The only saving grace through this whole thing was an amazing woman named Susan. She was so much help to me. I think she’s a saint! The company should promote her to president. If they do that the company would run a lot better believe me. Thanks for all your help Sue. I really appreciate everything you did for me.
I sent a transmission to them because Scott the salesman told me they didn’t have any that they could sell me, I had a leak I could not detect, so I decided to have a full rebuild done and service to find any damage to the case. When I got back my “Rebuilt 700r4”transmission still had all the gasket seal that I put on it and it was still leaking when I put it back in. They painted it and painted over the gasket seal and Told me that was from somebody else. Yeah!
It was me trying to stop the leak. The warranty department will not respond to me whatsoever. It’s been a month and a half and I still haven’t had them contact me with any kind of resolution. I spent $3200 to get a leaky transmission. Does it make sense to anyone?!!!!
The warranty department service is horrible. Don’t buy from these people.
# Promote Sue to President of Monster Transmission!!!!!!

Ordered a 4l65e built to 650hp spec. They sent me updates every step of the way so i knew where things were at, and worked with me on the shipping. Put it in a year ago and have easily put over 10k miles on it. I do autocross, and lots of long distance driving. It's in my 99 Camaro SS which is mildly tuned (400hp). I put a 3500 stall converter on when I installed it. The Transmission has performed flawlessly to date, good firm shifts. Shipping was really pricy, but that's what I get for living in Hawaii so i cant put that on them. I saw the bad reviews when I was shopping around, and some of the YouTube videos left me with the impression that the customer either didn't know what they asked for when they ordered it, or didn't have much of a mechanical background and user error was the problem. Sure there might be negative reviews, but you can find negative reviews on anything if that's all you're looking for. I believe they sold me a solid product, and it has performed well in the year that I've had it in. Thank you MONSTER

This company is nothing but a joke they still your money and lie to you repeatedly when you try to get answers from them they took my money over a month ago and keep giving me the run around about how it's has parts on back order and they will try to make it happen but it is bull they are just jerk offs don't trust the salesman named Sam he a puppet for the suit company

What a flipping joke! We bought a yukon transmission from monster transmission about 1 year to 1 1/2 ago. The 3rd and 4th gear started slipping again even after we have been on top of the transmission flushes. My husband tried to reach out multiple times to get the warranty going so we could get it fixed. It took them about 8months to actually reach back out to us. Then Chris told us that it was because they had a large turnover of employees that's why it took them so long to get back to us. Okay I can be understanding of that if they were willing to take steps to rush a new transmission to us (we are in the middle of moving states). Not our fault that their part and their employees were incompetent. But no, it's going to take another 3-4 weeks before we are going to get a transmission even delivered and this is all while we have to have our vehicle torn apart and rush our old transmission to them. It's funny that we have to rush and bend over backwards to give them our business but they aren't doing much to earn ours. PLEASE IF YOU CAN, GO SOMEWHERE ELSE!

I ordered a 4l60e transmissin from monster I got to reading there reviews an changed my mind. I canceled the order the next day. They charged me 800 dollars for a restocking fee. Idk why because they hadn't even took it off shelf yet! They did give me store credit for the 800. I went ahead an used store credit to get a 3200 stall converter. I bought a trasmission from a diffent place 3700 hundred. I put transmission in with monsters torque converter. I drove car for about 30 miles an pulled in to car wash an car wouldn't move at all. I had to get car tower home 250 dollars. I took transmission back out thinking it was transmission. I shipped transmission back to were I got it from 250 dollars along with the torque coverter I got from monster so they could test it all for me 300 dollars. Transmission tested out good with the place I got transmission from torque coverter. When they tested it with monsters torque coverter it wouldn't do anythang. So they asked me if it was OK if they could cut it open an c what was wrong with it 100 dollars. They cut it open an found out when monster put it together they welded threw the outside to the inside an welded everything together. So I called monster an the told me to send pics so I did. Michelle told me she would get pics to techs an the would get back with me no later than 4 business days. I call after a week an sue says she would get them get on it. A week later I call an they say they were backed up but they were looking at it now an get back with me by end of day. It's been 3 more days an nothing. Now I got to pay 250 dollars for shipping back on transmission an torque converter. Sooooooooo don't buy from monster!!!!!!!!!!!!!! Don't buy from monster!!!!!

I needed information on what transmission best fits my application so I began a chat. I received a call from Frankie Maldonado and he walked me through my order and answered all my question. I was very happy and my buying experience was fantastic a big thank you to Frankie M. and Monster Transmission and I am excited to installing my Transmission.

Thanks Monster for the opinion of your Chevy 350 combo package with 700R4 for my 1986 Chevy Silverado k10. I’m waiting for it to arrive at my house which is all so really nice. I have everything ready to go and starting tomorrow I’ll be taking out the original transmission and the original 305 and putting your 350 package in it. Dealing with John Blair one of your reps was all good and he was very helpful answering my questions. And putting things in place and getting everything going. I hope that it lasts me a lifetime and I can pass it on to one of my sons. Thanks for everything so far.

Absolutely one of the best customer service I have come across in a long time

I would rate a minus 1 since there rip offs and do not give you the $500.00 core return!!! It's been months!!! 40 calls to them!!! Company is not reliabe!!!!
