    I say this with the utmost respect: You are the shop teacher that every kid needs. The way you explain what you are doing, the methods and devices you have built to make working solo possible are inspirational. You’re like an off-road Adam Savage.

    Tom, one of the things that makes your videos interesting to me is the way you accomplish difficult tasks alone. It is not easy to do that. I grew up around an auto repair shop that had at least four mechanics at all times. Often, one would call on another for help. You do it alone - and that includes filming what is happening. Congratulations on making the hard jobs look less hard! 👍👍

I truly appreciate your balance in explaining a challenge and then talking through the problem solving with us - not too much in depth/minutia, but I truly appreciate the level of details provided vs. 'glossing over' or not showing any of that, as some channels do. Keep up the great work and content!

    Tom, I followed you from Matt’s to your own program and I’m pleased to see it is doing good. Your program improves every episode and I look forward to upcoming episodes.
    My background is Quality Engineering in the Vehicle Maintenance arena. I was responsible for a fleet of vehicles that traveled throughout the US with a reliability score over 99%.
    This amount of reliability was neither cheap nor quick.
    One of the areas contributing to that reliability was understanding and applying the proper torque to various types of fasteners. I picked up on your application of anti-size and remembered how application of lubricants was addressed in the torque manual. If you are interested in pursuing this matter further, I would be glad to discuss it with you.
    Keep up the good work! Robert

      Preventive maintenance is what my father taught me. I've never paid anyone to do anything to any of my cars, well, except for balancing my wheels after I mount my tires. After untold millions of Miles we've had no major mechanical breakdowns,, one of our secrets is a quart of Rislone, with an oil change, it disolves sticky gum and varnish that build up in a pushrod internal combustion engine, try it for yourself you'll notice how smoother your engine runs in 500 feet or 5 minutes.

    Watching you work on the transmissions made me remember another crazy memory. I was driving a 1968 impala. 327 turbo 400 12 bolt rear end. The girl sitting right next to me bumped the transmission into reverse at about 15 miles per hour. It made one hell of a noise. Shook to a stop. I put it in gear and drove. It survived. The skinny bias ply tires probably helped.

    • @lint2023
      @lint2023 3 หลายเดือนก่อน +4

      Decades ago a similar car passed me on a country road. One of the passengers did the same with the gearshift. The front driveshaft u-joint snapped. The driveshaft dropped to the road and caught, and the car pole vaulted over the front and landed on the roof. No damage to the front bumper. I was in a perfect position to watch and I came to a stop before a car load of passengers slithered out. Wild.

      My friend had a 455 HO in a lemans. He got a temp license suspension, so I would drive him to school in his car. It had a manual valve body in the transmission. You had to put it in nuetral at a stop sign, or it would creep forward. The shifter was pretty janky and easy to put in revers. It had all the tire you could fit in it. We would both laugh when I missed nuetral. That honkin engine would just spin those big tires, no prob. Like spinning on ice.

    You can always put a vice grip on the flex plate and then it will stop at the bell housing. Usually that works. Also, on the show “Fringe” Dr. Walter Bishop sings the Noble Duke of York Diddy. Good job, Tom. I’ve never seen a transmission going that easy.

    A flat piece of steel bent to the shape with a little bit of hangover for a mudguard.

    When you said I’m going to use what I got I remembered. Around 1975 I removed a junkyard blown up small block chevy motor from my 1962 corvette. I put a 396 built big block in it with a boom on a 3 point hitch on the back of a massey ferguson tractor. The 350 broke because I didn’t know i shouldn’t rev it to 6 grand every day 😂. I was 20 years old. Another mistake was blowing up the numbers matching 327 and dumping it in the wrecking yard.

    My favorite trick to keep the crank from spinning - use a double box end wrench and run a bolt through one end into a a torque converter / pressure plate hole on the flywheel / flex plate, and then another bolt through the other end into a bellhousing hole. Locks it down with no prying acrobatics.

    Great content Tom! Dig Doug is coming along well it should never an amazing wheeler. A couple thoughts, I work by myself a lot, a $12 LS flywheel holder (uses Starter mount fits into ring gear) is useful. Also, if you fab a little bracket that picks up the adapter mount you can use it to support the Trans while removing only the xfer case. Likewise could pull engine/Trans with transfer case still supported.
    Excited to see more progress!

    I’ve enjoy your videos here, got to know you over with Matt. I’ve wondered a bit your past work, then here you mentioned the Navy , I served on the USS Archerfish (SSN 678), from 70 -73. I was a Sonar Tech.
