    Thanks for the video. I just got my second Insight. The first Insight did not have this issue, it was an automatic. This one does have issues when downshifting from 3rd to 2nd and from 2nd to first. I was surprised to see this is a known issue and that it is pretty straightforward to solve.
    If you have a video on how to drop the Insight transmission and how to re-install it that would be great.
    I am now wondering about getting a core transmission that I can rebuild out of the car, then just install it when it is ready.
    Thanks for the content.
    Keep up the good work.

      I don’t currently have a video on how to drop and reinstall the Insight transmission, other than a pretty unuseful time-lapse of one, but here is one: ua-cam.com/video/kq-q26UH9iM/v-deo.htmlsi=x1thJADRjQoF4IVf Rebuilding a core transmission outside of the car and then installing it when ready sounds like a smart plan. That's exactly what I did. It was good practice removing the first one from the junk yard too.

    A big thanks for making this video, I watched it numerous times when rebuilding my transmission. Just thought I would point out that you did not apply liquid gasket to the 3 bolts with the spring and ball bearing. The manual calls for this there, I did notice some sealant on the threads on my bolts.
    I would also say that with lining those 3 notches on the dampers, care must be taken because its easy to not get them lined up, I wait for an audible click instead of lining them up.
    I'm not sure if you should line up the nut on the countershaft with the old mark, I retorqued mine again to 80ft lbs using a vice, and I went passed the mark. I guess it doesn't matter but just thought I would point that out. You would have to put the countershaft in a vice with plywood to hold it when torqueing to 80ft lbs.

    Great video and thank you for making it. I just replaced the input shaft bearing a few nights ago and used this as my go to for knowledge. Everything went smooth other than getting that clip to snap around that bearing.
    For anyone who struggles with getting the clip back on the bearing, you actually have to drop the trans with some force. The counter shaft (or whatever it's called) kind of gets stuck just a few MM more in towards the trans. Also, when I install a new bearing, I put it in the freezer to make install just a little easier.

I thought being able to downshift is the whole point. Also, I also thought that double-clutching was how one can downshift without synchros, but it sounds like you're saying that, once the mod is complete, double-clutching will make the grinding worse. Thanks for the video, by the way. I just bought my first Insight, and need to do this work, so it's a big help.

      @@philcarey25 Being able to downshift is the whole point to doing the synchro modification. What I was trying to say is, if you just downshift to 3rd and then neutral until you come to a stop, you would never experience a downshift grind because you're not downshifting. This is true with or without the synchro mod. If you decide you want to downshift to 2nd and 1st, then you should double clutch and that will keep it from grinding without the synchro mod. Once the synchro mod is complete, you can downshift all you want and it will not grind. Does that make sense?

    Awesome! I rebuilt my transmission with a set of Gearspeed carbon fiber synchros and left the double cone action on first and second. Those are still brass, not carbon fiber. First gear was busted again within a year, so we know for sure it's a design flaw. I guess I won't grind the tabs off until it's time to replace the clutch again, and even at that point I'm not sure it's worth the hassle of taking the transmission apart.

    When you broke the case free, you said at 8:16 "the snap ring is already loose". I noticed the same thing on my transmission. I broke the case free with a pry bar and it just came up without having to release/open the snap ring. I wonder why this is? It seemed the same thing happened to you also. I wonder if we bent something. I was trying to open the snap ring before I released the case though. Maybe the force just pushes the snap ring out.

    • @mjspiess
      @mjspiess  Рік тому

      Hmmm, interesting. I've done two of these now, but I feel like the other case and snap ring gave me some fits. I can't remember now. I think what happens is that entire shaft slides down just a bit with gravity once you release the snap ring, because in order to resecure it, you need to flip the transmission over and let that shaft and bearing slide into the snap ring. At 39:57 I talk about that process.

      The three marks that are together are for reading ignition timing. The single mark by itself is #1 piston at TDC. I believe the center line would be 12* and the ignition is controlled by the ECU so it would be a way to see where your ignition is at with a timing light. At 900 +/- 50 RPM no load condition the timing should be 12* +/- 2 degrees BTDC.

    • @mjspiess
      @mjspiess  3 роки тому +3

      Yeah, they are generally reliable. The main issue they suffer are the splines on the CVT flywheel are initially lubricated with long-life Honda grease that is held in by a rubber O-ring. If (when) the O-ring deteriorates, the grease "escapes" and the splines on the flywheel eventually wear down. At that point, the engine runs, but the flywheel doesn't engage...you are basically stuck on the road. It isn't predictable, but it is very likely to happen with all high-mileage CVT Insights.
      Also, CVT's don't have the "lean burn" feature 5 speeds do and average 10-15 mpg less. Unless the CVT is super cheap, I'd hold out for a 5 speed. The 5 speeds should always be double clutched while down shifting. If you do this, it will never grind or ruin the synchros.
