It seems this may be a "****** characteristic" for Chrysler trannies. When I'm rolling into my garage very slowly at idle (flat) the truck seems to lunge, or slighty lurch a little. Otherwise drives fine, shifts fine, 4wd all works well, the truck will crawl up my (steep) driveway in 4L. This only seems to happen when rolling forward (or reverse) very slowly. Thoughts?

this is not when it down shifts?
Nope... Flat ground, in drive, rolling into position to park. It almost feels like it is trying to scoot. Kinda feels like the brakes are sticking a little, it's difficult to describe.
Sometimes it can lunge when going from park to drive or reverse, that's the 42rle.
If it's doing it in 1st gear may be a sign of tuning. TPS, throttle body /IAC clean also..??
Check for codes with a good shop scanner.

****** codes or engine codes? No CEL. Can I check the ****** codes with my obd2 scanner? I've never had a scannable trans before, that would be very cool. The one thing I haven't done is clean the TB etc. I will do that this weekend. Mine does have the classic intermittent idle stumble as well.
Funny thing is, this "issue" is somewhat intermittent. I read somewhere it is a common occurrence backing up on an angle due to servo timing and not the strongest torque converter in the world??

cant do ****** codes w/ regular obd2 code readers.
Clean the IAC while you are at it.

Can the 04 version be cleaned like the the older version? Hit it with TB cleaner and wipe until shiny? I may pull the entire TB and go to town? Can't hurt!
Is there a specific Trans type of code reader? Or is this a shop only tool (big $$)?

as long as it is for a TB, you should be good.
Pull the IAC out and clean it too.
big $$ for scanners that can read ****** codes.
