As suspected, the solenoid did not fix the issue, although it wasn't working consistently, so it's not a complete miss from the cannon. From the service manual chart, if 1st clutch pressure is good (which it is), then it's either the second clutch or the shift valve assembly. Can there be any insight to the results of the second clutch pressure when there is no pressure in 1st gear and only partial pressure in second gear? I would find it difficult to believe that the other causes, feed pipe/guide pin would be the cause. If that was the case, then there may be other issues (chunks are bad) If it end up being the clutch. I don't know if I have the time or interest to replace. Do you have an estimate of the hours a shop would charge to replace? Thanks again for you input. It is appreciated

So I went back and tested the shift solenoid and it's inconsistent. Sometimes it engages with 12v and sometimes it doesn't. I have fired up the proverbial parts cannon and ordered a new one. Its scheduled to be delivered on Thursday, so I have my fingers crossed. Thanks for your help.

I was able to fabri-cobble an adapter to test the oil pressure. I hate the fact that metric bolts have to have 15 different thread pitches. The access ports for the oil pressure testing are M8x1.5. Not a stand size for the gauge sets. I ended up taking a caliper nipple, turning it on my lathe, and soldering it to a separate fitting. My first attempt with JB Weld was not as successful. The results are not what I expected. The oil pressures for the 1st clutch is within specification. The second clutch oil pressure was 0 in first gear and only read 50 psi in second gear. There is a list of probable causes, and I will need to RTFM, but any suggestions as what might be the most likely issue? Thanks, Remnar "Free is worth saving up for"

Appreciate the input. This is my first quad and I didn't think I purchased a project, but here I am. I have cleared the code, I still have the issue. It's weird that the code displays on the Power Steering light. The transmission is a DCT. I think my next course of action is to check oil pressures. That should help in the diagnosis. Taking reading of oil pressure at 5k rpm with the wheels free is an interesting test....

Thanks for the response. I will check the sensor numbers at the ECU. I did go back and check the TP sensor resistance, which I missed, the sensor resistance is within spec. The interesting thing is that I turned on ignition before re-connecting the TP sensor and the error code showed up on the check engine lite in addition to PS light. I am close to clearing the TP sensor as the problem I want to go through the troubleshooting on the transmission, which seems to lead me to check oil pressure. Readings with wheels elevated and engine at 5k rpm sounds interesting.

New member here, I have searched here and other places and have not found an answer to my problem. As the title says I have a 2014 420 Rancher that recently started having an issue were the revs before the clutch engages. I have checked the oil level (per the service manual) and replace the Valvoline ATV 10w40(less than 5 hours) with 10W30 GN4 for good measure. I have used the "pin" method to pull a DTC. I shows a 8-1 which is a TPS error. This makes some sense, as if the computer doesn't read throttle position correctly, it could have this symptom. I have checked the source voltage, and tested the TPS off the quad with a Fluke and a power supply at 5v. It is smooth and does not seem to be a bad sensor. I am confused by the DTC, because the PS light blinks the code, not the check engine light. However, there are no PS codes of that value. This condition appeared after a couple days of driving in the cold (~32°) and driving though some water/bogs. A couple questions. First has anyone seen this issue, and do you have any suggestions? I have followed the troubleshoot right up to the point of replacing the ECU, which I don't seem to have one on the shelf :) Second, anyone used a OBDII reader with an a 4pin adapter to pull codes? If so, what system do you use? Beyond the rev issue, the quad runs and starts perfectly and when it decides, the clutch grabs tight (no slipping)
