Title: What is this plug??
Post by: 86silverado on February 08, 2012, 04:49:18 pm

I just had my 700r4 rebuilt in my 84 chevy c10 and swapped motor out and got rid of all emissions and its all back together and the tranny still shifts into overdrive really quick and lugs along,  the kit that was put in was a mr shift noyoyosyskokal kit. Supposed to make that go away.  But on the harness coming off trans every plug is hooked up except one,  its a red two prong plug with a yellow and a light blue wire.  I cant find what it plugs into anywhere.  is this my problem??

     Can you tell us what you have plugged in already, that will help with people throwing out ideas.  Can you take a pic of the end of the plug and post (so we can see shape)
     Have you done the adjustments to the linkage and TV cable if equipped ?

Yeah i will get it all tonight.   The vacuum switch is hooked up and another plug off tranny is hooked up.  Switched motors and got rid of all emissions so there is alot of plugs now.  No cruise an went to mech gauges.   Nothing i took off has tht style plug. Ill post pics

     You should PM either Vilezombie or Captkoas, those are the two I think would know, sometimes you have to wait till members get around to seeing your post.  Not everyone has time to go through all of them everyday.

I have looked in alot of wiring diagrams and still cant find it.  I think it may have something to do with lockup but where does it plug into

The wiering for the lock-up solenoid is very simply if you want to check it and make sure it is all hooked up. Or you can make your own simple version for maybe $20 or less if you have spare stuff laying around.
