OK so here it is, the DIAGNOSIS!! I'm not really happy about it, and I am really irritated with myself, but it is what it is.
I got a call from the shop foreman on Friday afternoon to hear where we are with the car. After he dropped the pan, what he saw was water in the transmission oil. Humph, that's not good at all. How did water get there is the $3500 repair question for the new transmission and torque converter that is needed, as well as complete flush. He had a very simple explanation. He was also very certain that it was NOT coolant from the radiator cooler. That would be a frosty color which it was not.
On my G8 he noticed my transmission dipstick tube that I installed a while back. Almost 2 years ago or so. He is seeing that it is not sealed where it goes into the transmission. I remember seeing it having a rubber O ring on the bottom of the tube when I installed it, but hindsight is always 20/20, that little O ring isn't going to seal out much of anything. For the past almost two years, every time it has rained, it has hit the tube under the car as spray, run down the tube, and slowly leaked into the transmission, where water is a very bad thing.
What I have been doing everytime or so when I change the engine oil is to open the transmission plug, drain out about 2 quarts of transmission fluid, (measuring it so I would know how much to put back in) and then re-add the equal amount of Dextron VI down the transmission tube, it couldn't get much easier. The thought is to maintain this car as I love it and want it to last for quite a long time. What has been really happeneing is that I was slowly killing the transmission.
TAKE HOME POINT--------------IF YOU ARE USING THIS TYPE OF DIPSTICK TUBE, CANADIANEH WAS SELLING THEM, PLEASE DO YOURSELF A FAVOR. CHECK THE SEALING OF THE TUBE INTO THE TRANSMISSION AND ADD SOME SILICONE OR SOMETHING TO PREVENT WATER FROM LEAKING IN.
From here on out, I am going to be doing what the manual says. Every 50k or so, drop the pan, change the filter and re-add to the correct level.
Please also everyone here understand, I am not calling out anyone I am really just trying to help out fellow members not have the same issue I have and save some serious expense.
