Upset beyond belief

I changed the o-ring on the th400 dipstick tube. While attempting to put the trans bolt back in that secures the tube, I fumbled the bolt down on top of the transmission case. I have been looking for that bolt for over an hour and have still not found it. I can't believe it. The garage floor is clean and the bolt is not there. The bolt washer managed to fall off and land on the floor. I have been working on cars for 40 years and have had this entire car apart. I have dropped many bolts over the years, but have never lost a bolt this big. Where might it be? Any ideas?

Re: Upset beyond belief

Check to see if it is wedged between the transmission case the dipstick tube. If the transmission cooler lines are installed, check there, too. If you have headers, I would check on top of the collector area.

See if you can pass a magnet up around areas you cannot see.

Re: Upset beyond belief

My guess, wedged between the trans and the floor lip that connects the firewall to the floor pan. It sticks down, I don't know, 3/4-1" and will catch anything.

Re: Upset beyond belief

When something doesn't hit the floor and I can't find it, first thing I do is grab my extendable air nozzle and start spraying every way I can in hopes of dislodging the bolt. Do you have longtubes? Top of the collector or wedges in the primaries? Flat spot on the trans case? Any wires, ground straps, or vacuum lines in the area?

The good news! It did not disappear. Think like gravity.

Re: Upset beyond belief

Sometimes I'll take a similar bolt and drop it in a similar manner and watch where it goes as it falls. A lot of times it will land right next to the one you're looking for. Sounds dumb but it does work.

Update on missing bolt. Thanks for all the help with your ideas! I really appreciate it. I had enough last night and went to sleep to get a fresh start this morning. I thought maybe it was against the vent tube, but I didn't see it there either. As mysteriously as the bolt disappeared, it suddenly reappeared. I used a long piece of coat hanger and asked the good lord for help and patience. The second I started to fish it up on the right side of the trans case, my wife came into the garage to ask how it was going? I started to remove the hanger to show her a similar bolt on the workbench and the bolt mysteriously dropped out of an unknown location. I really don't care at this point where it was hiding, all is good and back together. Thanks again for all the help. Steve

I have the Flexible Claw Grabber Pickup Tool Long Reach Curve Spring Grip Tool, and the flexible magnet grabber pickup tool long reach. Very cheap on Amazon, and I have used them many, many times to save me, ie, grab a carb. bleed that I dropped in the carb., grab screws that I dropped in the back of the air gap manifold, grab screws or nuts that are stuck in the headers, --- or even grab socks that fell in back of the washer and dryer. They have put a smile on my face many times through the years and are officially "life savers". I could not see having to live without them.

Re: Upset beyond belief

Had something similar happen last weekend. I was working on my headlights and dropped one of tiny retaining ring screws; couldn’t find it for the life of me. Pulled out the air hose & nozzle and blasted away behind the bumper, under the frame, etc. Lo and behold, the little devil popped out onto the floor!

Re: Upset beyond belief

It's happened to every one of us who has ever worked on cars. Except on TV... those guys on all the Motor Trend shows (Garage Squad, Graveyard cars, etc) never seem to waste an hour looking for bolts that have disappeared into inconvenient places.

Yes, the flexible claw grabber tool is a must. It as saved me many times over the decades. I do however, need to buy a new one since mine had finally broke last summer. I will also invest in a good flexible magnet.
