I've got what seems like a shudder in the trans under light acceleration in most all gears, it's a 5 speed. Highway speeds and around town. The vibration is sometimes fine and sometimes coarse. Anyone experience this kind of thing? I replaced the left cv axle and intermediate shaft/awd actuator. Changed trans fluid with Mopar ATF+4 twice, transfer case fluid with the right Mopar fluid, rear axle oil, still doing it. Any ideas? I had the local trans shop guy drive it and he couldn't say what it was. Thanks.

 

How are the u-joints in the various driveshafts?

 

I tugged and twisted both and the rear was solid, front just had very slight play in the splined shafts. The trans shop guy said the front joint of the rear shaft is a fluid joint but it was tight. So...

 

It has a carrier bearing also and that was solid. But I want to get it up in the air to really get a hold of things and move them. All I have done so far has been under the car on jack stands.

 

Not having to slide around on your back makes inspections much more pleasant. and you can see stuff better as well.

A dry joint will 'feel' fine, but, under load, when it gets hot, may cause of vibration..... That's a hard one to diagnose though, without disassembling everything......

 

True dat! If I can get it into a shop soon I'll let you know. BTW, like your V10 taste!

 

Yeah, I love everything about the truck, except the gas mileage. If I break into double digits, I feel I am doin' good. Fortunately, I don't drive a lot. So, not too much of an issue.

 

Well the shop said it's the trans with a torque converter shudder, kinda what I was thinking too. Have 3 options Jasper, Mopar, forget the 3rd. Mopar actually close to the cheapest at $6900 yikes. Ever heard of a Diablo tuner fixing a trans problem? Saw a guy on u tube where that happened.
