Hello. I removed the axle to the rear wheels over 12 months ago to make it FWD. Twice this month the transmission disengaged from the engine as if I pressed the clutch pedal but didn't. I stumbled on a temporary fix. I jacked up the front end and spun the front passenger wheel then it would drive normally. The same fix worked the second time it occurred. The MT fluid is fine. Clutch has about 35,000 miles on it. I searched the internet without success. Can you help me determine the problem? Thanks in advance.

Hi,

This is an interesting one because it has a manual transmission. When it happens, you say it feels like the clutch is depressed. Is there any noise associated with it? Truthfully, the only way that can happen is if the pressure on the clutch disc is released allowing it to disengage. When this isn't happening, does the clutch slip at all?

Let me know.

Joe

Joe, thanks for your response. There is no noticeable noise or sound. I'm driving on a slight uphill grade (twice) in fourth gear and the car starts to decelerate even though I'm giving it more gas. The CR-V will coast to a stop. The clutch feels the same when I down shift to third and second but has no affect on the engine. The clutch slipped before I had it replaced but not since.

Another observation, when I had the CR-V jacked up the first time I spun the passenger side tire and the driver-side tire spun in the opposite direction. The second time I had the car jacked up I spun the driver-side tire first but the passenger-side did not move. I then spun the passenger-side and then the driver-side spun in the opposite direction.

Hi,

The tires turning isn't anything out of the ordinary. If there was a gear issue in the transmission, transfer case and so on, you would hear it. I honestly feel the pressure plate is bad and allowing the clutch disc to release from the engine. Something is happening allowing it to release or it is slipping again. Do you only feel it in fourth gear on a hill?

I just read through everything related to the rear differential and how the transfer case works on the vehicle. If functions in front wheel drive unless under heavy acceleration from stop or the front tires spin faster than the rear. I keep coming back to the clutch itself.

I am going to ask another tech that I trust for his opinion. He will most likely jump in on this thread.

Yes, on both occasions the CR-V was in fourth gear. I appreciate your assistance.

The transfer case in the car is called a torque control this means it evenly distributes engine torque the front and rear drive wheels evenly. It sounds like the transfer case overheats due to no rear wheel drive. Here is how the transfer case works in the diagrams below.

Thanks, Ken. I removed the drive shaft to the rear wheels over 12 months before I started having problems. It occurred twice in 2-3 weeks.
Are you saying that the solution to the over-heating transfer case is to re-install the drive shaft to the rear wheels?

What he is questioning may be the issue. It makes sense. If you still have the driveshaft, install it and see if the problem is gone. Interesting it would take 12 months, but different conditions can cause new issues.

Let us know.

It could take that long for the viscous coupler to wear out. Reinstall the shaft to see if the problem goes away. Please let us know.

I'll re-install the drive shaft this weekend and drive it around. I'll also replace the rear differential fluid and report back.

So far, so good. After installing the drive shaft, I drove the CR-V for about 40 minutes without incident covering the same ground as when I had the 2 problems. Both problems occurred at around 10 min. After departure. While not conclusive, I'm encouraged.
