Hello. I have recently purchased a 2013 Chrysler Town and Country minivan. I do all of my own work on my vehicles and recently did a pan drop, replaced the transmission filter, installed a pan with drain plug and refilled with about 6 quarts of ATF+4 (Castrol Transmax). About a week before that, I extracted about 4.5 quarts of ATF and refilled. I use AppCar diagFCA to monitor the ATF temp and use the published level chart to verify I have the correct level (just shy of the max level). Based on the chart, I measured and put score marks on my engine oil dipstick on the backside with min and max marks. When I removed the pan, it was very clean with a tiny bit of metallic paste on the magnet and the fluid was quite clean, reddish and reasonably transparent. Before and after the 10 or so quarts I swapped out the trans shifts are silky smooth and there's no TC shudder or slipping. The van currently has about 140000 kms on it.
My mind tends to get the better of me and I sometimes wonder if I've done things right after the fact.
Here are my questions:
1) If by chance the filter was not fully seated in the pressed in seal, and air was being sucked into the pump along with ATF, would there be bubbles in the transmission fluid? And, if there are never any bubbles on the dipstick, no slipping and both line pressure and CVIs are well within spec, is that definitive proof that there isn't an air leak at the filter?
2) As mentioned, I have AppCar diagFCA. It is capable of TCM diagnostics. The van doesn't have a TCM, per se, but it's integrated, I believe, into the ECM. Which tests would you deem important to determining the overall health of the unit? As stated above, I have already looked at the clutch volume indexes and line pressure.
Thanks in advance,
Adam
