With the transmission rebuilt and back in the truck, this video covers shifter linkage connection, TV Cable connection and adjustment, and my solution for the torque converter lockup connection.
Really enjoyed your video, I swapped my 71 from a 3 on the tree to a 700r4 this last winter and it’s so much nicer to drive. For my converter lock up I visited my local U pull it wrecking yard and removed the factory lock up set up from a 83 and used the brake light switch as well this allowed me to let the system work as it would in my truck, I did however install a switch to shut it off when putting in town but otherwise I have lockup in 3rd and 4th gear. For my transmission lines I used a set for a 72 chevell worked like a charm, no bending required. Again great video thanks for posting it.
Very nice. I wasn't expecting my rear gear change to raise my RPM as much as it did on my TH350 with my '72 C10, so now I'm researching the 700-r4. Doesn't seem too difficult, just gathering parts and getting the driveshaft shortened.
@@hdrolling my gear change was kind of an accident, but I had always planned a 700-r4 anyway. Pretty straight forward conversion, this was my third, and wanted to document things, like the exact amount the crossmember shifted back, and the driveline length change. When I told the driveline guy to take 3” off the front section, he commented “700-r4 conversion, huh?” 😁
The second line is a return to the fuel tank to prevent vapor lock. It lets a small amount of fuel return through a .060 restriction, just enough to keep the gas from boiling on hot days.
Excellent work. I watched your first video earlier this week and was disappointed that part 2 wasn't available to watch. But I was excited when I saw it posted this afternoon. I'm likely going to put a 700R4 in my '72 C10 so I'm very thankful that you detailed everything so well from start to finish. I'm curious how GM handled the TV cable and TC lockup on the squarebody trucks that got the 700R4 in the 80s. Is there a reason why it's not possible to adapt that particular setup? Thanks again for making these two videos!
Thanks for the input, I really appreciate it, and hope it will make your conversion go smoothly. As far as the TV cable connection, I did consider looking for a GM bracket, and use an OE cable, but the Lokar setup is so adjustable for both the throttle and TV cables, it's my preference. I showed my TC lock solution to my transmission builder, and his comment was that it is similar to what GM did, but they also have a speed sensor integrated to enable it. My interpretation is that it is so integrated, it's not a just module you can take out. Good luck with your project.
I found the parts on Amazon.
