Ed Louie Posted September 29, 2012 Report Posted September 29, 2012 Hi All- Im Ed Louie. Ive been creeping around this forum for a couple years since i got my '47 Plymouth business coupe. Thanks for all the info. Ive put Old Daddy's disc brakes on the front and now have used the Wilcap adapter and mounted a 700r4 with a 2000 Explorer 8.8 disc brake rear axle. Everything is just about ready to get back on the road except the throttle valve cable. My question is: Has anyone hooked up a 700r4 throttle valve cable to the stock 1bbl Carter carb? and how did that go? I am considering making a piece to put it on the linkage on top of the block. Any ideas or pictures would be awesome! Thanks Quote
Plymouthy Adams Posted September 29, 2012 Report Posted September 29, 2012 make your kickdown linkage as is comparable to the GM and you will then adjust out the freeplay in same said manner...this is critical for long life of the 7000R4 you should be able to make a fixed plate tothe manifold/carb so to affix the original GM adjuster..

DJ194950 Posted September 29, 2012 Report Posted September 29, 2012 Fist i'd think Wilcap would at least have a diagram to build the link to the carb. since they are making the adaptor. Second, try using the search function on Street Rodder mag. Several years back they had a diagram that showed the required travel for the cable with drawings and specs. for the 700-r4. Best of luck. If you find the info, i'm sure others on this forum would appreciate if you posted it! Doug Quote
greg g Posted September 29, 2012 Report Posted September 29, 2012 Everything on the stock set up moves the wrong way for the cable action of the TV cable. Keep in mind this cable is controlling a voalve body to acertain where the upsifts happen as well as when to down shift. The Cable must be pulled out all the way at WOT. and slightly slack at idle. You may need to route the cable to the pass side inner fender in order to get the pull gong the wight way. I do noththink the angle/movement on the bottom of the throttle linkage arm is sufficient to pull it completely out. What are you using for a trans oil cooler? This is another critical problem area with the 700 series. How did you wire the lock up? Quote
DJ194950 Posted September 30, 2012 Report Posted September 30, 2012 From what i've READ MANY times, the shift points are very important for driveability, and I agree with Greg's points! A new bracket could be built to tie to the throttle linkage at a point that the cable gets pulled as the throttle is opened. The proper amount of pull is eccential to shift points. The biggest issue from what i've READ beyond shift points is that the cable really NEEDS to set properly at idle position also, otherwise cooling oil flow can go to 0 and ruin the trans in short order! A company called TCI makes a valve body that guarantess full pressure for cooling fluild regardless of tv cable position. Never checked price! Adaptors are commonly made to adapt this TV cable to Edelbrock and Holly 4 bbl. carbs to correct the ratio to match the 700r-4. I hope someone makes this adaptor to the stock throttle linkage as a friend and I are planned to put an auto trans behind a flattie 6 in his 49 bus. cpe. 700-r4 or turbo 350. Next project! You all know how that works! Best, Doug Quote
Plymouthy Adams Posted September 30, 2012 Report Posted September 30, 2012 I have never adapted the kickdown of the 700R4 but I have made my own brackets to convert a 1968 big block 727 to cable kickdown..it involved making a bel crank for the throttle plate to get the correct movement of the cable..it is not a hard task to accomplish..

Ed Louie Posted September 30, 2012 Author Report Posted September 30, 2012 Im pretty sure i can fabricate a "correct geometry" arm off of the linkage arm in the center of the head. It seems to pull the right direction. I have a universal adjustable cable and an adjustable mounting bracket. Might need to use the head bolt to hold the bracket. TCI does have a constant pressure valve that wont allow the transmission to be ruined ($335). @greg I have a 30" dual pass finned cooler mounted on the underside by the frame, i may use a regular one in front of the radiator as well. I have a lockout kit ($90). Ive converted to 12 volt and an alternator. Ive made linkage so it shifts with the old 3 spd column shifter, and left the clutch pedal in with a spring. Most wouldnt know it was automatic at first look. Quote
40P10touring sedan Posted September 30, 2012 Report Posted September 30, 2012 ED, neat idea for the dummy clutch pedal.... As for the kickdown linkage you could make a bellcrank that pivots in the middle, hook the TV cable to the top and the bottom one to the carb- it'll go in the opposite way with that set up. Keep the throws even and matched. You have a 218, right? The only person here who has a 700r4 in his ride{now} is Lee...I want to do the same trans set up and had never even thought of the linkage issue, yet. Quote
40P10touring sedan Posted September 30, 2012 Report Posted September 30, 2012 Just PM'd Lee, hopefully he can help us out when he's not busy with his son's wagon....inquiring minds wish to know! Quote
blucarsdn Posted September 30, 2012 Report Posted September 30, 2012 In lieu of using a 700R4 for an automatic trans conversion, consider the GM 200R4.. The 200R4 trans is the same size as a TH350.. Several trans rebuilders are installing up-grades to the 200R4 which eliminate the problems that the trans had in it's early applications.. The Ford C-4 AT is also being used in many old cars, some of which are the Ford flathead V8's and Buick straight eights...Bill Quote

I will be installing one this winter and have not figured out the servo linkage yet---I have twin C/W carbs and the set up will take some thinking......Lee Quote
40P10touring sedan Posted October 1, 2012 Report Posted October 1, 2012 I thought...ahhhhh...you said you drove it Lee? Quote
BeBop138 Posted October 1, 2012 Report Posted October 1, 2012 (edited) I thought...ahhhhh...you said you drove it Lee? When you were here I still had the T-5 in the car---I have not had time to install it. I don`t want to take it down during the driving season. I never said I put it in????:confused: Check out my post on the Dynamat install 7-5-12 I talk about my winter project.....Lee Edited October 1, 2012 by BeBop138 more info Quote

Sorry folks, I was wrong.........don't tell my wife! After some recent research, I'm thinking the 200r4 might be my way to go... Quote
Ed Louie Posted October 1, 2012 Author Report Posted October 1, 2012 I would have chosen the 200r4 as well but i already had the 700r4 in my garage. I have a plan for the TV cable and will post pics when I get it going. Good news is the floorboard almost fits without too much adjusting! Quote
