Transmission Chain Toro from70`s
Hello Oldsmobile community
I`m mike from Germany and owner of an Olds Toronado GT built 1970. When I start the Olds in Park position there is a nock,nock noise in the chain box between Engine and Transmission. I brake and shift in Drive Pos. the noise is away. When I brake now off and the car moved forward the noise is back -nock,nock. I think the chain is bad. Or??? Now my Question-can I change the chain when the engine is not moved out? Or is there enough space under the hood and I can moved the Engine some inches forward? Where have I the chance to buy the best chain? please excuse my bad english. and thanks for infos.

I'm positive you need to pull the motor and the trans to get to that chain. I think your best bet on finding another chain is to find a car that is being parted out and make a deal on the removal of the chain and shipping. It's not an easy part to take off the car. Good luck. Sorry about the poor German.

Welcome to ClassicOldsmobile! You've come to the right place to find help on your Toro. These are sweet and unusual cars (I used to have a '69).
There appears to be a removable cover over the chain, but I'm not sure there is enough room to remove it (entirely), its probably pretty tight against the firewall. But you might be able to get it unbolted and off enough to inspect the chain to confirm that is the source of the noise.
Here's a post w/ some pictures that may be helpful:

You might also consider posting this question in the Toronado section of this board.

You need to talk to member EightballZ.
He is in Germany and also has a '70 Toronado.
He's done quite a bit of work on it, so he may be able to help.

I've never heard of a Toro chain failing either. My guess is a loose torque converter bolt.
Either way trans will have to come out for access- I don't think there's enough room between the cover and the firewall to slide the trans back far enough to do the work.

Hello Old`s community
Thank you very much for so much good helpfull info. I rebuilt the starter and there is a small window where I can saw the bolts from the flexplate. They are all very fast. In Feb.2015 we have time (my friend and me) to built out the Engine. Than I can wrote you what has happen. Now I have contact eightballz,a German guy from our Olds community.

Oh wait....... if there is only one chain, and if it drives the input shaft of the transmission, how is the transmission pump driven? Isn't the pump (on a "regular" RWD trans) driven directly by the crankshaft via the TC shell through the outer hollow shaft and the two-notches, while the trans input shaft is driven by the fluid-coupled impeller inside the TC via the splines?

The pump is connected to the rest of the transmission via oil galleries, and the converter is connected by the chain.

It looks like the noise is coming from under the torque converter cover.
You may just have some loose converter bolts. Remove the cover and see if you can get a wrench on them.

Hi Eric
I think the torque converter is on the other-engine-side. The picture where my finger was, is the transmission side. There I can feel a small klong with my finger while the engine runs. I rebuilt the starter and there is behind than a window where I saw the converter and the flexplate.The bolts from the flex are very firm(solid). Are there other bolts in the chain box?

Hello Olds Community
Now I`ve change the chain and the Toronado runs like the first day. What has happen: The owner before me change years before the torque converter and when they built in the engine withe the trans the make a damage in the steel cover on the top where the chain runs inside. So the chain and the cover was bad after time. I have luck because here in Germany sells a people a brand new original chain for 200$. When you remove the steel cover you see the chain. In the big gears where the chain runs over are holes where you must remove the seeger rings( both- torque side and trans side) The most work is to remove the engine with the transmission. Now I´m happy and will write it you. Mike

Hello Mike, I am happy you were able to solve the problem and get the chain at a good price. The Toronado is not an easy car to work on so you were brave to take on that repair. It is good it got repaired correctly this time and should give you years of driving pleasure.
