I think i have tranny problems......

[roon_VR]

Hi Guys/Girls I'm after for some opinions

I suspect my auto transmission is on it's way out. If i accelerate heavily, the change from 1st to 2nd slips. Doesn't slip if its at comfortable acceleration. Also, If i drive over 80 km/h or on the freeway, my car violently shakes if i accelerate. This is in 4th gear cruising. However, if i change it to 3rd on the freeway, it doesn't shudder. Some opinions/suggestions will be greatly appreciated!

Thank you,

+1 haha i thought the same thing lol

sounds like clutch plates are burning and slipping, try service and add sum anti slipping fluid. or run up your codes and see if its a solinoid. and if your having trouble for your tranny go to bali they are cheep and a dime a dozen

for a really good tranny go to Thailand

I agree, should be more careful when wording thread titles. I was going to direct you here The Gender Centre Inc. as I figured they would be more help than a Commodore Forum

Thank you,

Check fluid level and colour - if OK and reddish or even slightly brownish add a transmission conditioner - one designed to stop slipping....
If the fluid level is low - top up.

From the sounds of things you probably are correct and your trans is on the way out...unfortunately.

When they fail, unless it is something simple like solenoids or dirt in the valve body, it is cheaper to replace or reco the entire transmission.
But that's just my opinion.

Not really, anyone could have googled it, just like I did.

The violent shudder in 4th gear will be the Torque Converter Clutch (TCC) stuffing up and not locking properly. My VS commodore does the same thing except mine shifts fine everywhere else. Im getting a new transmission instead of just the TCC as I was told it would cost close to $800 for the just TCC and then I would still have the original 170000km old gear box in there. Instead I am getting a reco'd transmission for like $2000, as its far better money spent.

I would also invest in getting a transmission cooler fitted at the same time
