Do I need this part?? Install

[84 c10 o skool]

I'm ready to drop motor back in and redo electrical.

Just want to make sure.. this switch/vacuum port is for lockup transmission??

 

[350runner]

Yup

Sent from the dust in front of you!

 

[marks86]

yes Im pressure sure that's for your transmission vacuum, do you have a 700r4?

 

[84 c10 o skool]

no i have a turbo 350 non lock-up.

The same switch was used for both.

TH350 only requires vacuum off the manifold not an object such as this. The TH350C uses a different setup which uses a connector on the left side of the transmission.

OP has a TH350 so this is not required.

I just got rid of a th350c and the lock up connector is in the same side... same vac switch I seen in the yards. Guess they could be different somewhere.

TH350Cs are a rare breed unlike the TH350

You can drop that in an envelope and mail that switch to me..

Boone my 1985 c10 has one that isn't in use if you'd like I'm sure we could work something out


1985 C10 305 for now 350 waiting for installation

Sounds good

Was it operational? I don't want the one from the passenger side for ESC, people get them mixed up all the time

Yea they are less desired. My Trans builder wouldn't even take mine for free....Lol sad but true.

I would leave it in place. You never know what time may throw at you Just tie the wiring up neatly under the frame at the transmission.

I am looking for the pig tail that connects to the TCC switch.

 

[smdepew1976]

My truck has both neither is hooked up. Im outa town with the holidays for the next couple weeks but after I get home I will snap a picture to make sure its what your wanting.
