HI, I am looking for a cruise control regulator (transducer) for a 1972 cutlass. I believe it should be part #554888. Would like it to be NOS or as nice as possible since i cant seem to find anyone that rebuilds them any more. Let me know what you have or if you know of someone that can rebuild them. I have a different style on my cutlass now from rock auto, works good but my speedometer reads 8 mph slow now. Guess i would like it to look and work correct.

Thanks as always for any help!

I have a transducer but I don't see a #

 

The cruise control should be a one to one on the input to output, you may need to change your speedO gear to correct the speed problem. Good luck.

Yes that is the same style as the one i currently have but i need the more square one.

My car is a 50,000 mile original car and speedo was right on the money till i put the Rock Auto transducer in it when i added cruise control. Thats why it doesn't make sense cause it should be one to one?

 

Should look like this but has a silver label.

 

Here is what I have in my NOS parts. Its dirty and untested but in theory should work fine. Bought this several years ago. I think its a later supplier for GM as it does not have the tag color you talked about.

Order a re manufactured Cardone #36102. It's for a 72 Cutlass. Rock Auto still lists it for about $76 + $20 core charge.

 

This is the one i have in there right now, works good just makes my speedometer off and of course that style isn't really correct for that year.

 

Its funny that is the 3rd number I have seen that's says its correct for my 72 A body car. Its hard to say which one is correct for sure. What are you looking to get for it?

Thanks Greg

 

I'm not sure on the 71 and up units, but my 70 transducer has one brass vacuum hose fitting (with a lock nut) that can be turned in or out to sync the set speed with the actual speed. Service manual says each 1/2 of a turn out on the brass vacuum fitting will kick in the speed two MPH higher.

 

I think i did adjust that when i first put it in because it would drop MPH before it would kick in and i adjusted that to get it to kick in as soon as the button was pushed. I will have to read up on that in the service manual.

Thanks Greg

 

I can try to get over to the storage building tomorrow to check on my sheet for a price. My guess is $150.

 

Ok let me know what you come up with.

Thanks Greg

 

My parts sheet has it at $130 plus shipping.
