Just this past weekend I read about problems with low level of auto transmission fluid. The problem was thought to be caused by leaking hoses which would drip onto exhaust system which would probably leave no evidence of leak. As it turns out that article somehow got misplaced. Before posting this message I searched a lot of TSB and recall sites to get some more info on this subject without any success. If any one else saw this article or know about this latest possible TSB please post. This subject was being discussed in the auto section of a local newspaper including other manufactures issuing TSBs.

If you read the users manual, there is no dipstick or other way for an owner to check the level of automatic transmission fluid.

I have not seen a TSB for this. If you can find specific info. please send me a site message with that info. so I can confirm it and put it up in the Recall / TSB forum. Do you remember if this was for the 2014 cars or 2015 models?

For some reason I'm thinking 2014. I'll keep searching. I'm pretty sure the leaking was described as leaking around the pressed fitting not the hose itself.

And that compounds the issue not being able to check fluid levels w/out a lift. BMW/Mercedes, Mopar, Ford don't even include a trans dipstick yet there is a tube for one. Drives me nuts how the trend is going away from owner maintenance and care....but since the C5, there has been no easy way to check auto trans fluid levels.

Could this be what you saw? http://www.stingrayforums.com/forum/stingray-corvette-tsb-recalls/6899-possible-recall-tsb-convertible-tranny-cooling-lines.html

Don't recall it specifying whether it was to do with cooling lines. What it said is low fluid level on auto transmission caused by leak from hose falling onto exhaust system. That much I am certain of. I'm trying to reach the editor of my local newspaper to follow up on this. Will see what happens.

Found the article in the auto section of NY times of 11/9. " A transmission-fluid leak could signal trouble in some 2014 Corvettes. In T.S.B. 14572 issued on Sept. 23, General Motors said the cause was an auxiliary transmission cooler line that was not properly sealed; the fluid would smolder if it dripped onto an exhaust pipe. Replacing the transmission cooler assembly is the cure."

Thanks. Read the same article but then I tried to find T.S.B. 14572 on some GM tech sites and could not find it referenced. Will keep looking.

So how do we know if we have this issue? Since it drips onto the exhaust are there any other signs of the leak?

Ask your dealer to check the transmission fluid level next time you are in.

The odor is distinctive and the area of the burning tranny fluid on the exhaust will be discolored and perhaps coated with residue / carbon.
