4l65e sport monster

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!

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.

6k miles

Got this transmission back in February and since put about 6k miles with some some light towing over mountains and it seems great so far it is a little louder than stock when shifting at low rpm it kinda chatters but other than that it’s been great

Fast shipping

I have yet to have the Transmission installed. It was shipped to a local shop for installation on a 1971 Buick GS and I’m sure that will be great addition to the vehicle instead of the original three speed looking forward to it.

Called and talked to Frankie for quite a bit he is very knowledgeable on his products. We own a shop in Florida and was the first time purchasing from them any questions I had were answered right away. Will definitely be back for more purchases in the future!

I received my transmission approximately 3 weeks after ordering, I found the box had been hit during shipping, so I checked it over to find the bell housing was broke and one of the gallon jugs of transmission fluid was broken open. I refused to unload it and told the trucking company to bring it back. I called Monster and sent them pictures. Krystal got right on it and started the process to get me a replacement. She kept in contact with me on any updates as they were trying to rush me a replacement. Costumer service was excellent. I received another transmission within a couple Of weeks. I installed it and put it to the test. So far no issues. I’m very satisfied with this company. A good idea to check your order before unloading it….
