I am awed by the people who thought to design and build this mechanism in this particular way! I'm awed by your ability to understand and explain to me how it works. Mahalo!

Very informitive

Great video..💯💯

Thanks for the explanation, it was very interesting and you made it very easy to visualize and understand.

Excellent video! Just bought a 79 Blazer and while the wife was driving home with cruise control on, the speedometer quit working and the car tried to speed up quickly. The truck had not been driven for a long time (years). She hit the brake pedal and cruise control came off and the speedometer never worked the rest of the trip. I suspect the gear drive got seized up like you mentioned. Thanks a bunch with your explanation, now I know what to look for!

Thank you very well explained.

Nice explanation. I encountered these back in the 80s at a Chevy dealership. I took one apart several times but couldn't figure out how it all worked. Now I know! Thanks!

You completely helped me with my 73 Electra, awesome video, thank you

I grew up in that generation that rebuilt stuff. If it came in a box, it came from the deal new. They may have hand reman products, but I never saw one. The original GM-Delco-AC in red “Ham” cans with Red strings pull and unseal the box then get your brushes, points set or distributor bushing. You couldn’t get parts for the cruise module but like you, I have taken them apart and couldn’t help think of the engineers who built a part that had to work as if stuck on, would be bad! Still surprised to how they designed these with some changes over the years. Glad you opened one up to show people the insides and how they worked. I am sure you have seen the light blue plastic signal generator inside the speedo that had a reflective surface for light and photo transistor, before magnet pickups pointed toward the tone wheel on the output shaft. Good video! DK, ASE master since 78 retired.

Thanks for sharing your knowledge on these transducers. I've always wanted to know how they worked rather than just replace them and move on.

good video, will have to check out your other videos. Hope you made another video hooking it all up and explaining every part of it, for us basket case viewers,

Thanks so much for the post. I should be so diligent with things I have learned over the years. My last upload was 2012. I've been tinkering with an original cruise control for a 67 Camaro. This transducer reminds me of a "glorified clutch" on a 1960's minibike.

thanks so much, hopefully i can fix mine off of a 75 Eldorado. if so this video would save me a hell of alot of money

thank you very much for your explanation

Literally trying to figure this thing out right now in a 1980 motorhome with a G van front end. Cruise doesn't work and I've cleaned up the spedometer cables so many times that this is where it's led me to. Fixing cruise and the spedometer bounce that never ends. Thank you for explaining it!

Awesome! Thank U......MM

Thank you very much! clear explanation. Now i can try to fix my cruise on a 82 Phoenix😎

good video training.thanks

Excellent video. Very good explanation. Should any parts be lubricated? If yes, which parts and what kind of lube. Thank you in advance.

liked you explanation of how servo works. my 84 el camino has had wire s cut some removed, could you go into more of the wiring where it goes to , and how it works Randy

Awesome information! I have a question, when you reinstall the drum, does it go to the right or left of the creep switch? My drum was damaged and and got another from the salvage yard. I don't want to damage the new one. Please let me know! Thanks and God Bless!

Thanks for explaining this. My 79 K10 has the single button cruise control. I've checked servo and brake dump valve. Not getting 12v at the hold or engage terminal when pressing single button on turn signal. I've checked all fuses in fuse box and all are good. I see 2 connectors to a cream colored module on side of steering column. Wondering when i should get 12v to transducer with my single button cruise control.

Thank you for this presentation working on this problem right now and my 76 Eldorado. Appreciate you! Would you happen to know where I can source the vibration isolation mounting bolts which attaches this unit to the mounting bracket?

Thanks, I'll bet dollars to donuts it's in this thing is the reason my speedometer is not working on my 82 Firebird Trans Am

Thank you so much for this! I'm about to rebuild my transducer from my 83 olds with a sparatic speedometer and speed control. Where do I find a rebuild kit for one of these? And what part usually causes failures?

Amazing explanation! Thank you ! I have been thinking about retro fitting this system in my old Chevy truck. When this system works. Does it work pretty good? Thx

👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍🤞🤞✌

A 'down to earth' presentation, thanks My cruse control activates as normal and then the vehicle slows down very slowly. It is still engaged, It just slows down.Do you have a suggestions?

What would cause my cruise control to continue to accelerate when the cruise set is engaged on a 78 corvette?

Hello, I've been restoring my 77 Lesabre. What is the material in the bottom cup with gasket? Trying to recreate it. V/R Greg

Do you know if this is the same thing for an 83 suburban with a 5.7l? Based off your video I'm wondering if my cruise not working is a possible vacuum issue of lack there of.

Good Afternoon, I was wondering I have a 1980 c10 big 10 with cruise control. My question is that my speedometer is not working. And I don't use my cruise control. Is my problem with speedometer cable cause by the magnet not spinning or bushing stuck.? Any info would be greatly appreciated. Thank you Robert. HAPPY MEMORIAL DAY 🇺🇲

I am having the same problems with my 78 Buick Lesabre. However that resistance spring has basically grenaded itself and it's wrapped itself all around. Any suggestions

I have one on my 81 Z28 that doesn’t work. The carb has been replaced with a Holley 4160. I want to bypass the mechanism altogether with a 1 piece cable.

Mine was packed full of dust and junk but there was a tiny metal ball stuck to the magnet sort of like a check ball. Is there supposed to be one anywhere maybe it fell out of or is it just more junk?

I’m eliminating head light vacuum system on mine going with electric ones but don’t want to eliminate cruise how can I go about it? Can you help?

YEAH!!! Finally found a video on these old things. lol. NOS (Mostly) Restoring a '82 k10 w/ 6.2 diesel. I'm trying to find one with "resume" since mine has it on the column. There are a few part#s from the '79-84 10-35 series parts book i own. but i can't find any that shows a resume for my year. do you know of any places/websites i can send some of the used cores to get rebuilt & myb converted to a model with a resume?

My cruise control transducer seems to work fine except when set it slowly accelerates and I have to hit the brakes to turn off. What could be my problem.

How do I fix mines will engage but then it will just pull faster and not hold ?

I hate complicate crap like that. Im getting rid of all that on my 79 g20 van. I hate the clutter.

Is there any oil or lube that you put in

Do you have to clock anything

Can this work with a drive by cable ls swap?

Can’t seem to find how to replace one on a g body cutlass
