    torque lock up

    that's what's confusing me, if i unhook term D the only ground i should have is the fourth gear switch so it should be grounding when it goes into od, but with D removed i get nothing, i guess maybe i have a bad 4th gear switch, is there any advantage/disadvantage to having the temp switch in...

    torque lock up

    it is a 2 wire solenoid and a 1 wire 4th gear switch, right now i have it wired like the attached diagram of what's inside tranny and it locks up in every gear, it looks like terminal B bypasses the switches and grounds the solenoid so it makes sense it would allways lock, when i unhook term D...

    torque converter lock up

    thanks everyone for all the responses, pretty sure my tcc is hooked up correctly i think i just need to get a tach so i can see it change rpms for myself to be sure. i was doubting myself after a self proclaimed square body chevy master mechanic swore that without the ecm and all the emissions...

    Corvette servo

    Have been hearing about upgrading 700r4 with corvette servo, is it worth it? Also is it worth upgrading to the billet? Does that make the od better/stronger? It’s in a 86 k5 daily driver but used for towing and off road

    f/w junction block to fuse block

    Yeah it’s a mess that’s why I’m taking it one wire at a time, I’m probably going to have to pull the bulk head plug off and see if there’s anything going on in between the connector and fuse block, right now just want to figure out how to get rid of the wire back feeding the fuse block

    f/w junction block to fuse block

    Yeah it’s been a adventure fixing all this, when I started the running lights would be on any time the key was on, if I turned on the running lights at the switch I could turn on the heater a/c fan whether the key was on or not, I put in a new headlight switch and found where they had the blower...
