Transmission Problems? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question
Is the P0705 still present or did replacing the TRS take care of that?
The symptoms point to an electronic issue. do you have a scan tool with full function capabilities to command the shift solenoids on and off?
We usually drop the pan, but if he also has a mechanic's stethoscope, you place the end to the transmission pan and have him connect the scan tool to your vehicle and go into transmission menu and go thru each shift solenoid, commanding them off and on while you listen. You should be able to hear them click on and off. Let me know the results
you are welcome and let me know the results
Ok, get me the fault code numbers for the solenoids so I know which ones
