I fitted a blue 253 and commo traumatic in the LH. Just had the auto recond, the bloke said it was cactus and he expected he'd have to do warranty work on it (apparently that bad!) It was shuddering.
Shifts fine and all gears work no worries now, no more shudder. But, there seems to be a ticking noise coming from the tunnel somewhere, and when i really put my foot down there is a rattle. could this be the auto?
My next guesses are a stretched timing chain hitting the cover? (if that's possible?)
Or maybe an exhaust leak? the exhaust has just been done aswell. I dunno anything about autos...
Cheers.

try exhaust leak first. with motor cold start it and run your hand over all suspect areas feeling for air escaping.
secondly check for loose or cracked flex plate.

I had an EF which made strange ticking sounds from the g/box at random times but more often when cold. Turned out that the bolts on the convertor were loose.

if its loose it will rattle.
were the bolts torqued up.
was or is the flex plate checked for cracking.
is the starter fowling.
to check start and remove the starter and drive.
for some reason ive found certine starters not fitting 100%

i don't think the flex plate had any major cracks in it. i couldn;t get a torque wrench on the converter bolts, so i did them up pretty tight. i might try pulling the starter motor out n putting it back in..
cheers.

ok. i finally got around to it this arvo.
No exhaust leaks.
Pulled starter motor out and checked. No probs there.
Pulled inspection cover off and checked flex plate for cracking. All good.
Gave coverter bolts an extra reef with the 9/16.
Put it all back together and it didn't seem too bad. Over the next 5 minutes it gradually got worse and ended up just how it was before.
Any ideas? Or should i just send it back to the guy who built the auto?
Cheers.

does the ticking noise happen when the car is stationary or moving?

Both. rattle only happens when i really plant it. worse in third. not so bad in 1st n 2nd.
I asked my auto guy about it and he said it sholdn't be anything to do with the auto. it's going in on monday coz the box is leaking but he reckons it might be the starter.
I pulled starter out today and put it back in. same thing as yesterday. fine for about 5 mins then gradually gets worse (rattle, ticking is always there).
Cheers.

The auto guy said the engine is "pinging." Apparently that explains the rattle when the engine is warm and when i put my foot down. Could someone please explain what this means and tell me how to fix it?
Cheers.

detonation or "pinking" as the origional term was, is the motor firing the fuel on the combustion stroke at uneven rates, many causes are possible with the main ones being timing too advanced, mixture too lean and even wrong spark plug selection, the list is many and varied and it can even be built into a motor with wrong compression ratio, chamber shape and sharp edges in the chamber.
anyway always start any engine diagnosis with ensuring the engine has been correctly tuned.

pinging has a lot to do with low octane fuel as well. have had a few cars that do not like standard unleaded.

put the 600 holley on today. Definitely not running lean. Will check timing tomorrow.
with the bonnet open and the engine running, there seems to be a ticking sound coming from the passenger side rocker cover. i'm guessing this might be causing the rattle when i put my foot down. tappets? rockers? lifters?
Cheers.

I love the tappets, they are generally a fairly individual sound, will increase in frequency with revvs and make a tapping sound!
