P0753 It wont shift past first gear after it warms up

the codes are OBDll and are available on line free.
Example P0740 The diagnostic trouble code or DTC P0740 stands for "Torque Converter Clutch Solenoid Circuit/Open Circuit Malfunction.
P0753 The P0753 code indicates that the shift solenoid in transmission shift solenoid A, which changes the gears based off commands from the power train control module



all codes are transmission related.

Your best bet would be to take your vehicle to a ASE certified professional . You do not have the tools to diagnose this or the information.
DTC P0753
The 1-2 shift solenoid (1-2 SS) valve controls transmission fluid pressure acting on the 1-2 shift valves to position the valves for the appropriate gear. The 1-2 SS valve is a normally-open exhaust valve located on the control valve body. A fused circuit supplies ignition voltage to the 1-2 SS valve. The PCM commands the solenoid ON or OFF by switching the ground path. When the 1-2 SS valve is commanded ON, the PCM senses low voltage. When the 1-2 SS valve is commanded OFF, the PCM senses high voltage. Refer to Shift Solenoid Valve State and Gear Ratio .
If the PCM detects a continuous open, short to ground or short to power in the 1-2 SS valve circuit, then DTC P0753 sets. DTC P0753 is a type B DTC.
DTC P0753 sets when one of the following conditions occurs for 5 seconds:
Condition 1 The PCM commands the solenoid ON and voltage feedback remains high, B+.
Condition 2 The PCM commands the solenoid OFF, and the voltage feedback remains low, 0 volts.
DTC P0758
The 2-3 shift solenoid (2-3 SS) valve controls transmission fluid pressure acting on the 1-2 and 2-3 shift valves to position the valves for the appropriate gear. The 2-3 SS valve is a normally-open exhaust valve located on the control valve body. A fused circuit supplies ignition voltage to the 2-3 SS valve. The PCM commands the solenoid ON or OFF by switching the ground path. When the 2-3 SS valve is commanded ON, the PCM senses low voltage. When the 2-3 SS valve is commanded OFF, the PCM senses high voltage. Refer to Shift Solenoid Valve State and Gear Ratio .
If the PCM detects a continuous open, short to ground or short to power in the 2-3 SS valve circuit, then DTC P0758 sets. DTC P0758 is a type A DTC.
Conditions for Setting the DTC
DTC P0758 sets when one of the following conditions occurs for 5 seconds:
Condition 1 The PCM commands the solenoid ON and the voltage feedback remains high, B+.
Condition 2 The PCM commands the solenoid OFF and the voltage feedback remains low, 0 volts.
What's this p91860 , no such code .

Have you check fluid level ? Is your check engine light on ? You have a bad shift solenoid inside the transmission ,more then likely . Have codes checked ,you mite have P0700 + code

P0750 - Shift Solenoid A

P0751 - Shift Solenoid A Performance or Stuck Off

P0752 - Shift Solenoid A Stuck On

P0753 - Shift Solenoid A Electrical

P0754 - 1-2 Shift Solenoid Intermittent

P0755 - Shift Solenoid B

P0756 - Shift Solenoid B Performance or Stuck Off

P0757 - Shift Solenoid B Stuck On

P0758 - Shift Solenoid B Electrical

P0761 - Shift Solenoid C Performance or Stuck Off

Is the speedometer working?

those are all codes for the shift solenoids in the transmission. very easy to get at.

The code is for a shift solenoid which should be inside the transaxle.
You may have to take it to a shop for repairs.

P0753 Shift Solenoid A Electrical its inside of transmission not very easy to replace it controls the shifting of the transmission
P0763 Shift Solenoid C Electrical its another transmission shift solenoid
P0758 Shift Solenoid B Electrical another shift solenoid now my question to you is your transmission shifting normal have you had any work done to your car recently like changeing any seals on your transmission to have theses replaced by a mechanic its gonna be very expensive i could tell you step by step how to change them with theses codes you should be haveing serious shifting issues if you dont have shifting issues reset codes and see if they come back if they do then it could be in the wireing harness comeing from transmission hope this answers your question happy holidays

If it shifts normally and then it warms up and goes backwards OK and the check enigine light works and isn't on while driving the trans has the right fluild and it's not low then the trans has bad troble. If the check engine light is on find and fix the reason Speed sensers Theres 3 leaks burnt fluild correct and see if its fixed the engine needs to run right and hit the right temperture as it runs. otherwise an expensivew rebuild is next or a used transmission.

You need to have the transmission flushed and have new fluid put in. As oil warms up, especially old oil. It loses viscosity and will not lubricate the gears as it should.
