Overall great unit. I have put approximately 500 miles on it and there hasn’t been any major issues. Came with all parts needed to complete the job and customer service was helpful. Would recommend to another person.

Awesome.

Im really happy with the purchase and customer service was excellent

Happy customer

Monster Trans was on point with their estimate for the build and ship time. They had everything we needed for a one stop shop. Friendly and professional crew on the phones. Very excited to get this in the car!

Awesome product

Timely shipping, great customer service, people that answer the phone know what they are talking about when it comes to transmissions, and I didn’t have to wait an hour to get on the phone with somebody. Transmission works better than factory and carries a warranty that’s unmatched in the industry.

2800-3200 Billet Single clutch Stall

Just recieved my order! Putting it in my StreetMonster 4l65e, just cam and head swapped my Escalade, HD TC wouldnt cut it, will provide updates in next couple weeks, installing it with rebuilt motor and getting it tuned next weekend🤠🇺🇸

My original OEM transmission failed and Monster had my replacement here really fast. Everything was included the first time and was correct. So far it's been great!

Excellent job

Monster Transmission really came through and even during the holidays. The transmission is well built and we are very pleased.

Street Monster 4l65e Trans

Installed a few months ago, at 10k miles, no issues, and she shifts hard. Got the 0-60 down too. Just grabbed a billet 2800-3200 stall to put in with my cam/head swap, just wanted to update at 10k, no issues.

Monster transmission

Great product and great service. Highly recommend!!

Best decision made

My transmission went down and I needed one fast. Shipping was fast, customer service is great, and pricing is far better than other options I looked at. Improved shifting and mpg with these transmissions. Will be doing business again!

Road ready 6l80E transmission

The salesman Terry was very helpful in the ordering process and making sure I received the correct transmission I needed. It was shipped promptly. After installation the transmission shifted better than factory. I’m still in the process of returning core so I can’t comment on it yet. Thank you Monster transmissions for the great service!

2017 Silverado 6L80 xmission overheated

purchased new, never liked the shifting, 95k miles, overheated on the highway had to get towed home. added thermal bypass, had fluid flushed at dealer. truck was shifting hard and sloppy with lots of torque converter shudder on the way home. did not drive it afterwards. took a chance it was just the torque converter and purchased stock 1600rpm, went for a drive today and it was so smooth and shifted so well, temps are in the 160's. thank you Monster for the advice on the phone and having the parts I needed available and on sale. I am very happy all around.
