4L60E
This was my first transmission build. I had just competed a new engine and felt I needed to help the transmission harness the torque. I really didn't know what I was getting into and what really needed to be replace to improve the transmission so I decided to change it all. This kit was complete except I would have like to seen the bushings included. All the sub kits where labeled and it was really hard to go wrong. With the help of a manual and videos it went fairly smooth. I would have like to had better help from tech support at Monster transmission. At the time they seem to be having difficulty with voice mail and never returned my calls. I don't hold it against them because I know how the tech world goes. The 4L60E really preforms well now. Shifts are firm and quick. It really delivers the power to the wheels. If should get the opportunity to build another I would get this kit again.

Kit was used to repair a Firebird with a broken sun shell and some function issues prior to breaking the sun shell. In addition to the broken sun shell (included in kit)tear down also revealed some burnt frictions and band. Everything in the kit was good quality and corrected all function issues. Transmission is working flawlessly and shifts are very stong. Would buy again.

amazing kit
I have heard about monster transmission from watching powerblock TV. The trans in my 01 suburban lost 3 and 4th gear I decided to rebuild it I jumped on the phone called and orders the mega monster kit it arrived a short time later every thing exactly how they advertised. I have never been inside a transmission before and I got an atsg manual for 4l60 read it cover to cover and proceeded to tear mine down and install the monster kit . everything works flawlessly it shifts amazing I've put 890 miles on it so far without an issue I couldn't be more happy with the service and there package kits monster puts together!! A++ for there quality I'm about to order a second kit for the junk yard transmission I purchased as a stand in till I could finish the monster kit. I've read so many things where people think they can watch a YouTube video and think they can build there own then they post things like its not doing this or that or it makes noises.. I think that's just ubsurd.. Buy and read the service manual from atsg and order your parts or the monster in a box from the pros that know transmissions
