Looks like a 66 or 67 Cutlass switch pitch assy for an ST300 or T400 SP. That controls your passing gear and torque convertor. One of the guys may have one, and some members have successfully repaired theirs.

lol, sorry :/

1967 Olds Delmont 455

dont hink its fixable, it snapped right at the base...

oldcutlass

I think the same part was used in a lot of models. Someone ought to have one.

joe_padavano

So that's not the original engine (not that it matters for this problem)

Yeah, see, with that 455, you don't need to slam the throttle as hard as before.

Seriously, what part broke? If it's a steel bracket, that's easily welded. If it's the aluminum housing, it might be difficult to weld correctly.

I am hoping to have time to take it apart tonight or tomorrow, but it appears to ne the base of the round thingy (whatever that is) switch pitch assembly, is what OLDCUTLASS said, sound right?

Yes thats the switch pitch detent for the trans,maybe try posting in parts wanted section.

joe_padavano

No. The "switch pitch assembly" is a solenoid valve and associated plumbing inside the trans. This is the electrical switch that activates both the switch pitch solenoid and the separate kickdown solenoid (which are why the switch has three wires instead of two).

oldcutlass

I was going to write "switch pitch switch and passing gear switch assy" but thought it might sound redundant.

imcgm

Joe, do you know where I can buy one? what is the name of the part?

thanks everyone, hopefully I can find one rather quickly...

Oldsmaniac

There should be lots of these around as just about all 65-67 b bodies used this part. Used though is your only choice as there are not reproductions. Thing is to see why it snapped. I broke one once trying to snap back the secondaries that would stick open on the Holley spreadbore. Usually a forceful quick tromp on the gas pedal would do it. You need to check that when the gas pedal is all the way down there is not any stress on the throttle rod.

joe_padavano

Only Olds and Buick used the switch pitch trans, and some cars used a switch on the intake that attached to the carb arm instead of on the firewall. Unfortunately, since A-body cars are more popular, you see those switches for sale. I can't say that I've ever seen one for a B/C-body advertised.

imcgm

so I need to post "switch pitch trans" for a B body in parts wanted? does that sound right? & thanks again for all the help guys!

joe_padavano

OK, one more time.

If you post an ad for a "switch pitch trans", you're going to get this:



You want a throttle kickdown switch for a switch pitch trans.

A quick ebay search found this. From a Jetstar 330 car but I am guess ing it would be the same. http://www.ebay.com/itm/1966-Oldsmob...70351b&vxp=mtr

oldcutlass

He say's it was not checked, which means it may not work.

Oldsmaniac

True but a non working kickdown/switch pitch is better than not being able to drive the car at all.... When these snap you cannot use the accelerator.

imcgm

you are RIGHT about that THANKS!!

imcgm

thank you all!

I am back up and running!!!!

imcgm

oh, and if anyone is interested I can post a better pic of where that part failed..kinda weird how it snapped right at the base....

thanks again everyone!
