Just got my truck front the shop. I have about 161xxx miles on my Yukon. The trany started to go out so I had a Mega monster trans installed. I can tell u what, it's like nite and day. It shifts very firm. On the highway it's surprisingly very smooth. I have experienced no more shift lag, it just slaps into the next gear. My Yukon drives like a new truck again and I couldn't be happier. Whoever is looking for a trans check out eatmyshift.com they have many different options. Their warranty is very good too. 3 years unlimited miles for a complete trans. I did a burnout and it just spun the tires like nothing. I'll put a video up soon o a test drive/burnout

Just goes to show what a well built trans can do for a vehicle.

Glad to hear you are happy with the new transmission :)

I plan on having some nice trans work done to mine as well.

lol I am on my 3rd mega monster in my camaro. They are up the road a bit from me. Here is the plant from my mega monster. This is what they call a HD plant. looks stock to me. Did all this while actually cruissing at 45mph as it was going into lockup in 4th. I thought a bomb went off. I thought I lost my exhuast or a drive shaft or even rear end. just the trans again. They have been good about fixing it once it actually breaks but a pain in the ass non the less. This is just my experiance with them so far so it's not that this is the way all of them are going to be this is just one mans experiance. Blew the first one up on stock hp and street tires. had a bad sunshell. the second was on my 383 lt1 and street tires. I have never race that car. It has never been to the track.

^ Looks like "mega monster" needs to start doing something different.....

"Blew the first one up on stock hp and street tires"- this should not have really happend with a well built "HD"/"performance" transmission.

Im sure they are some what good at what they do.however,seems like something is out of whack.

Damn that sucks. I hope mine last a long time without any problems. I would hate to have to mess with my trans again. Thnx for sharing your experience. Did u drive it normal and slow or kind of hot roding it around putting stress on it?

This is why I think there is no such thing as a 'built' 4L60e especially if you were just cruising in a car that is roughly 2000 lbs lighter than these SUV's. Add the stress of any additional power, the extra driveline parts for 4wd guys, a lift, bigger tires, or do any towing and you're on borrowed time unless you babysit them.

So i called monster transmission to ask about my install and reliability. They stand by their transmissions and warranty saying they are top quality and they have had little or no complaints about 4l60e unless whomever installed it did a ****** job. Meaning they took shortcuts by not putting in all new parts. Well Im hoping my trans stands up to the use I put it through.

I am actually on my third mega monster. Something out of wack has nothing to do with it. I broke the second one in very very very easy. I did maybe one good traction run on the street before this happen. They will stand behind it so I say beat the piss out of it so you can shake the pugs out.
How do you screew up trans install to make internals break?lol
The one that is in there now was another story. I had to pay because my warrenty was only for 1 year. and even though it had been less than a year since the 1st one broke I had to pay 400 for the trans and new TC witch I was fine with because again I was in a bind. This one they called me to pick up and I went to get it and the guy said yea we just got done test driving it with your converter on it so it is all ready to go just install it and fill it. No need to take the TC off and fill it because we already did and ran it. So I install the trans and had a ***** of a time because of a bad bolt so 3 hrs later I am done and ready to fill it but I have a deap pan that I run and it was not on there yet so I went ahead and put it on. Well when I dropped the stock pan the trans was bone dry inside. not a drop of trans fluid. I was pissed because I now had to take it back out and check the converter which was also dry. This was the weekend so I left them a message and told them I was pissed because it was not tested. I ran the car sunday and monday morning and then got a phone call from the owner. He said I am sorry but we f'd up. I asked how and he said well your trans was not done yet, thats why it was not tested. I had asked them for 5 pinion plants and what happen was they did not have any so they just put it aside with the 4 pinion plants. He told me he did not know if the trans was compleat or not so he said he would build me another. I should have said ok and done it but I was in the middle of moving and packing so I needed the car to run so I could get it over to the new house. I left it at that and told him if it blows up again I will take him up on the offer and he said ok. Long story but in the end this type of shit always happens to me. You may not have any problems at all but with my luck...I will. lol Just one mans story and as I have said they did cover everything every time and even pro-rated the one time out of warrenty.

If your getting the 6.0 truck engine that came in the 2500's or even the 1500hd's get the 4l80e trans that is usually bolted to it.(Just check the RPO codes first) The 4l80e is the modern day th400 only with over drive. an absolute beast of a trans. You could hit a 4l80e trans that came from the factory with 500hp, stickey tires and track runs everyday all day long, all year long hot lapping it and not have to touch it. That may be a little much but they are tuff as nails from the factory. Get the engine trans and wire harness and slap it all in and go. That is what I have been thinking about doing if my 5.7 ever gives up. Only thing holding me back is cash flow. But if you can find one in a junkyard, take that thing and don't look back at this lazzy 4l60e. You have to have an LXX PCM to run the 4l80e or an after market controler. Thats the only thing that sucks about it but if you are going to use a 6.0 LQ4 get the trans, wire harness and PCM. Steal that shit if you have to lol.

I have a SS mega monster installed inside my 2 door. It has 100 miles on it.
I had nothing but trouble with this company. The tranny is still not right and they made me drive to brooksville back and fourth 4 times to pick and drop off trannys. I only recieved half of my deposit back, I really felt like I got RIPPED the **** off. I had spent COUNTLESS hours on the phone and countless hours driving to and from Brookesville. The thing shifts SO hard it nearly rattles the truck to pieces. I'm bringing it to a friend of mine thats going to get the thing on a lift and hopefully swap out the accumlator and the valve spring and everything else that made it a POS in my opinion. Then will see how long the thing holds up.

It will soften up a bit in about 1k miles. They use a really good clutch pack (about the only good parts they use) and untill they wear in compleatly, they are neck snappers. Your story sounds like mine. I took my trans back to them the first time about 3 or 4 times. They mod the valve body for thier shift kit. I don't know if what they do to them is compleatly reversible. It maybe. Any time you use the HD clutches though they are gona be neck snappers for a bit. I went with the mild shift kit and everytime I have reinstalled it after thier rebuild it is really rough on the drive train. It will calm down a good bit once they wear in.

The firmness of the shift is not just the transmission or the servo’s, but the setting of the “Force Motor Tables” in the ECM. You can make any shift as soft or as hard as you want with pressure.

If you know someone that can edit the OBD-2 computer, spend some time on the tranny pressure settings. (force motor)

Every time I install a new transmission, the first thing I do is to take my transmission guy for a ride. He drives and watches the transmission pressure and I make the changes to the computer as he calls them out. We adjust the trans pressure from idle to WOT in each gear. Tables are most often pretty close so it just takes a little tweaking.

Pressures will run from around 70 psi at idle to over 300 psi, depending on the pump. One of the tricks to making these 4L60, tranny’s last longer behind large power, is to squeeze the ¾ clutch pack tighter than stock to keep them from slipping.

Seems like most guys around the forum here want the trans to shift hard. I would suggest that you set up the “performance switch” and program the computer to increase pressure by 40%. That way, you can have a smooth shifting trans for day to day driving and whenever you feel the need to jerk your neck, throw the switch.

You should also know that a stock OBD-2 is trying to soften the shift with the torque control. They also lock up the TC gradually to make everything smoother, rather than just going to 100% lockup.

I always recommend going to a stand alone TCU for the tranny. It’s always a money issue for most. Reality is, you will save money in the long run, by buying fewer transmissions. :)
