I'll let you know if that works. Is the resistance within the specified range? Did you find and correct the condition? Thanks everyone for your thoughts and insights. Is the Shift solenoid mounted externally and where? The numbers below refer to the step numbers on the diagnostic table. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The solenoid receives ignition voltage through circuit 1020. I do all my own maintenance and repairs on all the cars ive owned, but have never ran into transmission problem in all my years. Car is a 2002 Volvo s60 T5 2.
I was going to replace the shift solenoid, but I cannot find anything on the web about where this thing is located. I haven't had to fix it in a while, so maybe I didn't decribe it correctly. From looking at the book, it looks like once you remove the clip, you will be able to pull the solenoid horizontally out of the valve body and then slip your new one in. The gap between the teeth should be at a 90 degree angle to the switch straight out. I would greatly appreciate any help.
I have a '97 auto 4wd. Other associated codes include P0750, P0751, P0752, and P0754 trouble codes. The Powertrain Control Module controls the solenoid by providing a ground path. The 3-2 solenoid is in valve body inside the transmission. I cleared the ses light after all the work was done, when I started the truck for the first time it came back on within 20 seconds and has not went out.
Thanks everyone for your thoughts and insights. The Powertrain Control Module controls the solenoid by providing a ground path. Any suggestions on what to do next? Does the resistance measure within the specified range? Thought I'd let everyone know that my tranny fell victim to the ole ignition switch. I have read other posts about a ignition switch causing the problem, but I don't have any other codes or any dash problems. What repairs can fix the P0785 code? The trans was flushed about 1 year ago, it's still bright red and dosn't smell burnt.
It is very sluggish when driving from a stop kinda like if it were a stick shift and I was trying to accelerate from a stop in 3rdgear. Is this even necessarily the cause of the problem, because an independent volvo mechanic suggested that even though the code is up this is most likely not even the problem. When looking at the gear teeth on the old switch, rotate the gear so that there is a single tooth to the left, then a gap, then the rest of the teeth to the right. The solenoid receives ignition voltage through circuit 239. This procedure helps narrow down the true cause behind the P0785 code. Did you complete the replacement? Well I guess atleast they good for reading the codes for free.
You mean the main pressure solenoid? I think I need to retest overdrive cause the issue to resurface. This should line everything up correctly and all you have to do is put everything back together. I'm also trying the acetone additive thing to see what happens. The solenoid attaches to the control valve body within the transmission. I had a squirrel problem about a year ago. How serious is the P0753 code? This only happens when I am shifting quickly and consistently usually at stop lights, stop signs, sudden turns, and stop and go traffic. Measure the resistance between terminal E and ground.
If the fuse is open, inspect circuit 1020, the solenoid and the Automatic Transmission Wiring Harness Assembly for a short to ground. This should disengage the locking mechanism sort of like those vehicles that you have to push the button to remove the key. The problems are so sporadic. Did you complete the replacement? Common mistakes when diagnosing the P0753 code A common mistake made by mechanics when diagnosing a P0753 trouble code is to replace a shift solenoid because they believe it has caused the problem, when in actuality the problem lies somewhere else. The solenoid receives ignition voltage usually from a fused ignition circuit. Has anyone replaced a shift solenoid, and where is it located? The trans was flushed about 1 year ago, it's still bright red and dosn't smell burnt. I'm also trying the acetone additive thing to see what happens.
Do both readings measure greater than the specified value? I've changed both the 1-2 and the 3-4 solenoids, no help. Did you find and correct the condition? Does the test lamp illuminate? Whether you need P0785 diagnostic tree information, P0785 diagnosis tips, P0785 technical information, P0785 diagnostics, P0785 troubleshooting help, or just answers to your code P0785 question, the is the place to go! The shift solenoids look like little boxes and are held in to the valve body with small clips one each. Did you find and correct a problem? I'm still not convinced, when the truck is cold, the problem occurs, service engine soon lamp, harsh shift into second, smooth shift into third, and won't go into overdrive. Happy Motoring awc109 I noticed my trans. This step tests for voltage to the solenoid. I am not even sure if I am talking about the correct solenoids. Refer to Electrical Diagnosis, Section 8A.
The symptoms of the P0785 code can vary significantly. Multiple stored shift solenoid codes usually indicates that a transmission component slippage or delayed engagement condition has occurred. How does a mechanic diagnose the P0785 code? If this issue is left unaddressed, the vehicle could become inoperable. Recently, the check engine light has come on. During a 3-2 downshift, the 2-4 band applies as the 3-4 clutch releases.
