Monster Transmissions , anybody ever use them ?

[CRJR45]

My transmission is acting up and I leave next month for a 5000 mile round trip hunt .
2016 2500HD 4x4 6.0 , the tranny is shuddering . Mechanic wants to put a additive in it after changing the filter and fluid , then see what happens . He thinks its the converter locking up .
I'm thinking replace it now and be done with it , as I plan on keeping this truck even though it has 145K miles on it .
Any advice ? Can you recommend a place that rebuilds transmissions ?

Dave Kindig uses them. Lots of other builders. I wouldn't be scared of a Monster transmission.

I already replied a few times over at Rokslide, I'd steer away from Monster and toward GM personally.

Yeah , I wondered if it was smart to post it in both groups , but was looking for as much input as I could get . I'm actually a retired GM guy , and I used to get a discount on parts , not sure if it's the same now .
The thing that sucks is I just put $3000 in this truck , brakes , CV axles , belts pulleys , plugs wires , and then ordered a winch and new front bumper , tire chains , air compressor , all kinds of stuff I might need .
Now I need a transmission . This is going to be a costly trip , LOL

Monster has a really spotty history in the performance aftermarket, too much marketing, not enough reliability. There are many better choices out there.

Interesting. I see top builders using them. Hard to top original GM I guess. mtmuley

I think they started out as a credible builder and then sold franchises, and the guality dropped .

Is it a 6l80e 4 wheel drive? If so I have a good one sitting here in my barn waiting to go in. I pulled it from my Jeep when I blew up my LS. I’m in SW MI.

It's a 6L90E , I think . The next generation from 6L80 .

Yeah, its the guys getting paid to use them that you'll see using Monster. For a 6L90e I'd use GM, for other transmissions it could easily be someone else. Most great transmissions have a niche builder, the 6L90 doesn't have a aftermarket following so I'd just go OEM.

The shuddering is the torque converter blades. One or more of them is cracked or broken.

Find a low mile used one and send it, I’ve done that several times and have no regrets using it.

Right , or at least thats my gut feeling . But what is a the collateral damage from that , ya know ?

Yes, the metal will wipe out the clutches in time. With that many miles it’s time for a rebuild or a low mileage used.

Wow , they're more money than rebuilt and have 100K on them . It's crazy how the rebuilding truck prices have shot up . My brother used to buy salvage Duromax's and rebuild them , now they're out of control on the prices .
