I agree with everyone about how amazingly helpful RRPhil has been in this forum and I was actually hoping he would respond to me this time too.
I have added some more (half liter) fluid yesterday and reset the adaptations with INPA. Engagement feels smoother but there is still that delay.
Another thing I noticed was INPA showed the transmission temp kinda high even after car was parked for half an hour after a 5 min drive. It showed 45c which I thought was too high. I will check again today and see what it says. I am planning to change that cable harness anyway because some of the solenoid connection plastic parts are broken..
Regarding the upper valve body crack, I took several photos (I will post one) and I did not see a crack there. Please take a look and let me know if you see anything unusual from the photo..
Thanks,
Ozzie
