Question about 2013 Jeep Wrangler
P0731 set . done pinion factor. newly rebuild replace k2 clutches ,k3 retainer and piston ,torque converter and valve body.. tried already with good condition tcm but still p0731exist
Stock car? stock tire sizes???????? not hacked with those hacking tools?"superchips, yahdah yah?
DTC codes not DVD, is video.
ok, p07xx, means TRANNY codes.
sounds like you need a tranny man. and why is your car out of warranty, very odd that.?
the key to fixing cars, with DTC errors is to understand how the
test is setup and what the failure means.
this can be easy or hard,
"GEAR RATIO ERROR IN 1ST" from 08 JK FSM.
are you working with zero FSM info? or no alldata.com with such
a complex issue. if yes, why are you? for $15bucks, (free really !)
The Transmission gear ratio is monitored continuously while the transmission is in gear.
If the ratio of the Input RPM to the Output RPM does not match the current gear ratio when compared to
the known gear ratio.
are you using a real scan tool that can SEE all DTCs on this car
if not you cant fix this car. sorry , cant.
because step 1 is just that.
area there any other DTCs (only works real tool , like my Innova 3160 or better.
Are there any Loss of Prime, Line Pressure Sensor and/or Speed Sensor DTCs present?
test 2 is the stall test .
do you get DTC 731 during the stall.>?
yes then it is slipping. only why is the question.
Repair internal Transmission as necessary. Check all of the components related to the UD and LR
clutches. Inspect the Oil Pump and repair or replace as necessary. Refer to the Service Information
for the proper repair procedures
and last, (first really)
did you read the FSM. page that states.
Perform 42RLE TRANSMISSION VERIFICATION TEST.
3. CHECK FOR INTERMITTENT OPERATION
USE a REAL scan tool DO NOT WORK blind and do not fail to
read the FSM. or you will go broke fast. I promise.
a real Scan tool, reads all JEEP codes. P1,2,3, and well, my FSM has 100s more..... read it.

What it might be is what it is, you will need to measure it and write it down, then when you reassemble it, put it back to where it was. The easy way is to mark the nut and the end of the shaft (center punch) and put the nut where it was. Should be 15-30 inch pounds.

SOURCE: torque converter clutch hang up
You mean the Torque converter Clutch Solenoid (TCCS)?
Its cheaper to replace it and your fuel economy will increase.
You could do this your self.

SOURCE: the trans won't upshift out
If the transmission is a 700r4, it could be the governor gear which is located on the side rear and have about a three inch cap with a snap retainer. If its not and you re-post the problem with the type of transmission, someone will probably have a solution.
