You can't fix 1975 clutch technology if they aren't willing to learn.

They would rather keep breaking gear boxes and spending money over and over and over than buy one good clutch.

I've broken more than a dozen 3rd gears. Have a buddy who used an 833 behind his Chevy. Broke four 3rd gears. He bought a Ram at the same time I bought a McLeod.

Neither one of us ever broke another one.


Using your logic. You could throw a couple thousand horsepower through one and it would be okay if using one of your recommended clutches. Also I don't use a 1975 style clutch.I use modern $1,200 clutches.....

Iโ€™ve been using a Ram sintered iron from Tim for 15yrs, a single Ram Billet 8โ€ and a twin 7.25โ€. Whether or not you like it the trans has limitations. Call Liberty, GForce or Jerico, Bubba at GForce is who I deal with.

Sorry to hijack your thread OP.

That's about half what a good clutch costs. Do what you want. I never said you can dump 2k HP through an 833. You did. That was beyond the design limits of the gear box. Any other box designed with the same limits as an 833 will take the same power levels.

When I was ordering some replacement parts for my Pro Shifted 833 from Liberty Gears ,we got to talking and the guy there said your going to blow out 3rd gear. What ? I never had a problem with my 11.40 motor , but 10.30 motor took care of 3rd gear on the first hard run. Dummy me rebuilt it and BOOM!!!!! That was the end of 833's for me.


it's ok to butt heads, just don't do it with a butthead

So back to the OP's question. Sounds like a 833 hooked to a Hellcat engine is just 3rd gear waiting to blow.

Does Mopar even offer a manual transmission behind the Hellcat or Demon engine or is it auto only?

Im pretty sure there is Only One choice automatic transmission option for the hellcat and demon. The same for the new scatpac as well.

$15,000+ motor $200 transmission, that will work.


Have a great day

There are manual transmission hellcats and I believe they use the same tr6060 as the viper

Seems quite a few people here must not have lived in the 70โ€™s with Super Stock, Modified Production and Pro Stock drag racing Mopars.

All of them had slick shifted 833โ€™s - SS/A cars in the early to mid 70โ€™โ€™s were going high 9โ€™s, A/MP with 426 at 3400 lbs going 9.40โ€™s.

How about the Hemi E bodies at 3800 #.

And they lasted how many 1/4 runs on forgiving tires.

I myself think even wanting to put a 833 behind a hellcat motor is simply goofy.

Ive a stack of busted up slick shift/liberty trans on the shelf, went to a GF101, never changed my driving habits and never an issue.

Yep, what he said and get an open 8 3/4 to go with it.

Controlling the clutch engagement I'm thinking controls the shock load the transmission sees.

This is all over my pay grade but I'd bet it's shock load that's taking out third gear more so than raw torque. The first shock load wounds it and then it's just a matter time.

I'm sure a detailed failure analysis would tell the tale one way or another.

I asked this question because I have had very good experiences with the 833. Not everyone wants to run a newer 6 speed trans and frankly I have no experience with the aftermarket 4 speeds some of you folks have mentioned.

I've run my Cuda at 3,000 lbs in the low 10's, high 9's for years without hurting the Hemi boxes. I had 2 of them. The gears would go back to Liberty for magnaflux and relug on a regular basis. If they said that the gear was cracked, it got replaced. They always sent the old gears back to me and circled the cracked areas. Eyeball inspection never found the cracks that they found until after they returned them. Magnaflux is a wonderful thing. Probably saved me from a ton of disasters. The right clutch goes a long way in transmission endurance. I think a 833 will work reasonable well behind a Hellcat engine with the right clutch. Power management like the factory software wouldn't hurt either.

Some people.. can tear up an anvil.
Shock loads, IMO, brake things, not so much the torque. Look at all those weak little parts in an auto trans, 727 with 904 guts behind a Hemi S/S, quite a bit of HP-Torque to run 8.15 with a 3200 lb car. Oh yea, it's got a converter to soften the hit, like a soft clutch I guess.
A friend runs a comp car, 6 speed. He "sets" the clutch so there's very little rpm drop (slips) between shifts. I've heard the sound recording from in the car, you never hear the shift. Now he does have the good trans, but nothing in the drive line has broken in all the years other than clutch wear-replacement.
700 HP and 3500lb cars, something better slip.

For you guys breaking third gear - what gear do you do your burnouts in?
