I ordered a transmission rebuild kit from Monster Transmission for a 4L60E. I ran into some problems building it. I was able to call Danielle, who set me up with your tech, though I forget his name. You guys were great and you shot me in the right directions. I'm trying again now to see if I can fix the problems. But, you guys are great, your awesome and when I need parts, you will be the people I call. Thanks again.

I placed an order for a Monster In A Box Rebuild kit from Monster Transmission. Let me tell you, it was all, all the parts were in order and they were all accounted for, fast on the shipping and probably some of the better quality products that I’ve ever seen, nice beefed up ready to go for my ’03 Hummer H2. Great Rebuild kit for the 4L65E, A lot of the components are nice and thick, nice heavy duty parts. I will definitely be working with Monster Transmission in the future and referring them to other people as I go. Have a nice day.

I was a little leary about the kit and having a transmission with a lot of miles on it instead of replacing it. Three days after the kit was in I drove my truck from northern Minnesota to Macon Ga. It was like a hole new vehicle and is still. 3500 miles on it and this thing is awesome. Good positive feedback on the shifts and smooth as glass when your not getting on it. AWESOME!

I have been very pleased. Thank you for doing business with me.
I ordered a couple of Monster rebuild kits from you guys. So far the Mega Monster in a box SS for the 4L60E has 400 turbo. I have been very pleased. Thank you for doing business with me.
