Is Something Wrong, Or Is The G56 Just Doing What A G56 Does?

[Ezriley]

So I traded in a 2018 Long Bed 8" BDS lift, 37" tires, etc.

On basically an identical truck with everything being the same except 45k fewer miles and a G56 transmission (35,000) on the truck I currently have.

I've searched multiple forums to see if anyone has the same experience I'm having.

I understand the G56 is louder than other transmissions that Dodge has run.

However, the 5th gear issue is sometimes extremely loud (I've added more fluid).

I'm waiting for the SAE 50 I ordered to get here to try that.

My biggest concern, however, is starting in 2nd gear.

I have to ride the clutch without giving any throttle for it to move without sounding like I'm running over a goose. (Makes a honking sound) wish I could describe it better, but that's what it sounds like.

Also, is it normal for a G56 to act like a rocket ship in reverse?

I'm not sure if the clutch is stock or aftermarket.

(Dealer couldn't answer a lot of those questions.)

It has an aftermarket gear shift that is 25" long, stainless, and resonates with any sounds coming from the transmission a lot more.

I'm not new to standard vehicles I had a 98 2500 in high school with the NV 4500, Tocoma's, samurai, S10, and jeeps, even if the clutch ever went out on any of those I never heard the sound this G56/clutch makes taking off in second with throttle applied, or you just easing off the clutch and not riding it at the bottom.

Anyone's insight would be appreciated.

No, that is not normal for an OEM clutch, but if it has a double clutch, ceramic or organic, they make sounds and rattle a lot.

Never heard one honk before.

You need to see what kind of clutch it is.

What does it do when taking off from 1st gear instead of second gear?

If you apply throttle starting in first now and again, you can hear it faintly, but it's hit and miss.

You have got to know what you're listening for to hear it (nothing like second).

Wish I'd have driven a truck with a G56 in it prior.

At least then I'd know what the stock clutch felt/sounded like.

Other than that issue and the noise in 5th at times, it shifts into every gear fine (no grinding or clunking), RPMs match the speed.

I’ve had my ‘18 G56 since Dec 2021.

I found it with 13,000 miles on it.

At 15000, I drained and filled it with Amsoil ATF +4 signature series.

At 50000, I drained and filled myself with Amsoil 75w-90 Manual Transmission Fluid 7qts each time.

I’ll be switching back to the ATF+4.

Transmission shifts are smoother with it, especially when the temperature is cold outside.

That said, I’ve never had any odd noise in any gears; sometimes, when the transmission is cold, the 2nd to 3rd gear could be touchy.

If you know, you know, LOL.

Since I owned the truck, the clutch always caught at the higher end of the pedal.

Good luck.

Please keep us posted.

By the way, 68000 miles, towing heavy, towing light, daily driving empty.

The factory clutch still feels the same.

I’m not on a diet.

I changed the oil every 10,000 on the engine and did the CCV filter at 50,000 instead of waiting for the service light to come on at 67,500.

That honking noise is likely your throwout bearing rubbing on the pressure plate's diaphragm.

Mine made a similar sound, and when it came time to replace the clutch, the throwout bearing and diaphragm had considerable wear where they made contact.
