Tailshaft - balance, vibration?

[uglyoldfatbastard]

There was thread on, l think tailshaft vibration, or something like that a few weeks ago. There was a tsb (gm service thing) can't remember exact details.

But bottom line was tailshaft was dropped to allow the back of trans to be able to come of, cleaned up & coated with lock tight & put back together. It was stop some sort of vibration?

I think @lmoengnr added that there was tsb about it & the fix?

I tried to find the thread, but couldn't.

I remember reading it as well just not sure where on here

That is the one and @PlenumBiscuit has a transmission from a 2014 in his car so it could be the issue.

Hi there.
Under light load the TCC can lock up early and cause a shuddering / lugging sensation. This can be fixed by a TCM re calibration. It is done using HP tuners and there is a guy in Adelaide that does this at a cost of $375.00. Changes the rpm point at which the TCC locks up.
Best way i can explain the shuddering i had is that it feels like the car is in too high of a gear and is laboring going up slight hills under light throttle.
I can let you know who does the TCM recalibration if you think it could be that. I was passed onto this mechanic for a TCM retune by Rowell & Searle after they checked my car for shuddering / lugging i was experiencing. Re calibration fixed it.
The recalibration will decrease fuel efficiency slightly but it's a small price to pay.

Hmmmm, six weeks since the last post and we never did hear from the OP regarding what it was in the end?

 

[PlenumBiscuit]

its about my car

i live in adelaide hills and its a pain to find a good mechanic up here

the issue has calmed, still exists, but its minor now

i still believe there is play in the front coupling and probably would like to replace the centre bearing as well

who do u trust with doing tailshafts, without being ripped off. i can do the couplings, but the VE tailshaft is more difficult isnt it for centre bearing ?

plus then i gotta arrange leaving it down the hill and possibly picking up next day ****

normally id just keep an eye out on FB market place for a recon tailshaft, but i deleted my FB

only watching gumtree now

Yeah, don't go using the big hammer YouTube method to get the bearing off as you risk damage to the uni. There would be places in Adelaide who can diagnose the problem and get it sorted @vc commodore or @someguy360 or @NORTI would likely know of some reputable places. I no longer have any contacts there as I moved away over 10 years ago now.

Last time I offered the OP some advise, he abused me calling me some choice names, along with a couple of other members...

So no chance of me helping the OP out
