I have been driving this car around now for about 2 months with the check engine light on. I had the codes read and was given the P0700 and P1776. I have flushed the transmission fluid and changed the filter. No change. I have replaced the input speed sensor. No change.
Here is what I have learned from driving with the problem. When the car is cold, first started I can speed up over 42MPH and slow down fine. But once the car hits the quarter mark on the temp guage, it will no longer work fine. What happens is once I go over 42MPH and go to slow down, the car will **** at 20MPH and will not shift out of 2nd gear until I stop turn the car off and restart it. The car will be ok unless I go over 42MPH and slow down again. Now once the cars temp hits about the half mark on the temp guage, I'm able to drive over 42MPH and slow down fine with no problems. Car runs great.
To me it seems like there is a short or bad grounding somewhere. I'm thinking about running additional ground wires to couple different areas on the engine and PCM/TCM and see if that helps. It also seems like once the low/high fan relay kicks in is when the problem starts until the high fan relay takes over and the problem stops. I swapped the relays but no change.
What do you guys think?

Problem in Low/Reverse solenoid switching closed during PEMCC in other words either shot in solenoid, circuit or most likely internal trans fault. Common is piston seal leak in L/R accumulator

But wouldn't the trouble happen no matter if it was cold or hot? The car/trans runs like a gem when the car is cold and when it runs a normal operating temp. It's just the inbetween when the car has the trouble. And it only lasts for say 15-30minutes during the warm up period.

It takes two cycles to set 1776 so during that time computer picks up L/R switching closed why? Intermittent loss of pressure, electrical anomaly

TJ 4.0L 42RLE
DISCUSSION:
If the vehicle operator describes a MIL illumination and the technician finds DTC P1776
Solenoid Switch Valve Latched in LR Position is set the DRBIII can be used to access
the event data screen and look at the “TRS Code” reading.
NOTE: The solenoid switch valve is not in the solenoid pack it is in the valve body.
TRS Code Reads TR2
If the “TRS Code” displays “TR2” it is an indication that the manual valve was not fully in
the OD position at the time the DTC was set. Check the shifter cable adjustment and
adjust if necessary. Also check the shift control system for excessive friction and/or routing
issues.
TRS Code Reads OD
If the “TRS Code” displays “OD” then a sticky solenoid switch valve is the primary cause.
Perform the proper diagnosis for the valve body. Inspect for foreign material in the solenoid
switch valve and plugs.
**FOR 2002 - 2004 LH MODEL ONLY**
**If replacing the valve body assembly for DTC P1776 Solenoid Switch Valve Latched in
LR Position first inspect the build date on the solenoid pack (Fig. 1) or (Fig. 2). If the build
date range falls in between 3001 and 0603 replace the solenoid pack not the valve body**.

Hey Docfixit,

You said earlier - "common is piston seal leak in L/R accumulator". Where is this located? In the Solenoid Pak or Valve Body?
