Bro V2R,
1st - someone I knew recommended me to some after market USA fuel injector cleaners, poured in 300ml and dissolved it with RM 50 fuel. Drove for 15mins and the shuddering reduced at least 30%. Got improved power, not sure about FC.
Next day, sent in to the workshop ...u were right about the mountings, Changed 3 mountings...problem immediately solved.
At the same time, detected some oil leaks on the GB & engine..had to change the seals, ATF, GB oil filter and etc...damage was abit high side ..but ride was once again perfect for my v6.
smooth & silent once again..

I have changed GB twice since that post, last was in Jan15. In spite of the new gb the shudder problem remains though not as frequent as previously. It occurs only during gear shift, randomly once in every 100-200 shifts like that. So I live with that and hope to change car next year.
I did the second GB change at a GB specialist in Balakong, Selangor. Diagnosing gb issues is a pain in the ass, normally if shudder is bad and frequent, a GB change is needed or you'll risk getting stranded somewhere helplessly when it fails completely.
YYC,
mine luckily wasn't a GB issue. it didn't felt like one actually but didn't know what it was...
but my repair cost of 3 mountings, Toyota ATF oil, gear oil filter, oil seals and other seals & misc items cost almost to a rebuilt GB change. approx. 1600
But in the end, the satisfaction was there, problem solved
if cant get it solved, I need to send it to V2R recommended shop...

What car you driving?
Idling speed 1k in N or D? If in D, 1k is ok, some idle at 1k in N, then engage D it drops then got vibration.
If in D at 1k still vibrate, probably engine mounting.
I will pm to you my mechanic contact
Yea u r right...its the mounting, all 3 dead, 1 extremely bad...the rubber fell out from the mount after dismantle..the earlier DIY treatment solved the constant RPM fluctuations due to dirty injectors.
