hoping you mechanics can help....
Got 2 codes on my Rubicon a little while ago....
P0869 - Line Pressure High
P1745 - Transmission Line Pressure Too High For Too Long
I was just driving home, stop and go traffic, nothing extreme. Does anyone know what this is?

Are you running an aftermarket programmer?
Typically programmers will up the line pressure for two things; Firmer more positive feeling shifts, and for more band-holding power for each gear.
If you're running stock programming, I think it is likely an internal issue with the tranny. It's been a while since I've been into tranny hardware, so I can't remember the name of the device or valve that controls pressure. I believe it should be external to, or at least within the valve body. Shouldnt be any need for a shop to drop the tranny and do a major teardown.
