PO755 code and transmission in limp mode.
I have a 2000 dodge Durango 4.7 motor 4x4 with a 45rfe tranny . In limp mode 2nd and 3rd gears only and have to shift manually to start in 2nd gear than to 3rd . getting a po755 code . first changed fluids and both filters and it ran fine for a couple of trips . than code and trouble back . next replaced SOLENOID PACK & Valve Body . again ok for a few trips and back again . Than replaced TCU drained fluid and replaced again . worked in for 2 trips and trouble back . also replaced tranny pressure sensor still trouble . Received 2nd solenoid pack and again ran ok for 1 trip than back . it seems that draining the fluid and refilling will clear trouble for a short time than back . has anyone had this trouble local tranny doesn't want to even look at this type of tranny .
