Built Stronger. Backed Longer. Monster Transmission

I bought a transmission from this company, and it was a great experience. The staff was professional, helpful, and knowledgeable throughout the process. The transmission was exactly as described, worked perfectly, and the price was fair. I would definitely recommend them to anyone looking for quality parts and excellent customer service.

Awesome transmission. No issues, works perfectly. High quality beast. Thank you!!!

I've been purchasing monster transmissions for years and every single rebuild has surpassed expectations! To top it off, the warranty program offered is the best I've ever found. I highly recommend monster to anyone I know that is in need!

I have roughly 800 miles on the new trans and converter. Shifts smooth and clean. No vibration/shudder,no gear hunting. Pretty smooth process very happy

I must say I’m very impressed with the quality of service provided by monster transmissions. The experience on the phone with the knowledgeable sales rep was a sure one-on-one experience answering any questions I had tailored to my specific needs. Just got the transmission put in so I haven’t put it to work yet but I feel like a little kid on Christmas just waiting to unwrap that present

Simple to install, only gripe is it doesn’t come preprogrammed

Installed the sport monster in my 2004 GMC Sierra 1500 with the 5.3 that I have done some work too about three days ago so far I’ve put about 50 miles on it. I did the hot flush on all the lines and remove the old cooler and went with the oversized Mishimoto trans cooler. Running the lube guard trans fluid that they sent with. It drove about 50 miles so far going to do the 500 mile break-in. Its shifts really firm and I’m really pleased with everything. No leaks. The stall converter drives great and locks up great. I am pleased with my purchase so far! Excited to break it in and see what this thing will really do!

Installed with the new transmission. All the instructions were easy to follow. Hoping everything works as expected.

We got this installed and it seems to work great! Fingers crossed that is lasts long. We did purchase the extended warranty just in case. The people at Monster Transmission were very helpful and our order came quicker than expected. Now we will see how well the core return goes.

Easy to order. They answered all my questions. Shipping was fast. Drives better than when I bought it new.
