What happens if you set it in "idle" mode at the trans with the kickdown unhooked and go for a ride. I am just guessing but I am thinking you should have an early but mushy shift.

Yes when the linkage is unhooked it shifts at 20mph
I thought I set it up properly but most likely I haven't
I suspect I need to lengthen the actuall rod that is connected to the carb
This rod has been modified by someone in the cars past
It's welded together
No sure if the length is right?
Looks correct but that doesn't mean it is
glides also have a second adjustment on the side of the tranny, look in your shop manuel for adjustment, its a little envolved but it smartens things up
The initial kickdown rod adjustment is, with the carb wide open, the carb linkage should be pulling the kick down rod as far forward as possible, this pushes the transmission lever as far as it can go. This gives maximum kickdown and longest transmission life. The modulator can be adjusted to set the 1-2 shift speed an normal throttle openings. Set the kickdown linkage before operating on the modulator.
Thanks Randy

The carb pulls the rod forward but the bell crank pushes the trans. lever back. When you let up un the gas, the lever on the trans. should spring forward. Also, there should be a small spring on the linkage to hold it forward on the carb.
Stay away from the band, you have to get the kick down linkage straight first.
When you started out I think you had a very early shift, correct?? Now that you have adjusted the kickdown to max. you have a late shift. If so, now you back off on the adjustment to get a satisfactory shift. With the throttle at wide open, adjust the linkage so it doesn't push so much on the trans lever. Adjust it a bit at a time to see if you can find the sweet spot. I think you said some of the linkage was welded or homemade, so make sure it's not binding etc. It should move freely. Your getting close!!
Right, you shouldn't have to let up on the gas to shift when everything is correct. Depending on how far down you are pressing the gas will have an effect on shift speed. Normal driving, the shift will be at approx. 20 mph, foot to the floor, approx. 60 mph.
It can be tuned to just how you like it. When cruising along in high, then flooring it, it should down shift, or kick down to low as high as approx. 45 mph.
I just looked at your carb thread and noticed you have the small kick down spring installed back wards. It should go from the linkage to small hole in the coil bracket. The linkage is spring loaded rearwards and the carb pulls it forward. You have so many threads going on about the same stuff it's getting confusing. Perhaps you should start to include pictures as you go so we can all stay on the same page!!
Randy , thanks for taking the time to help me in such detail
your right I have made it sound confusing at this point,sorry about that
I think from your last few posts I should be able to dail this in
The spring will get changed first
then I will work on finding the sweet spot
If I still have trouble after that It will be photo shoot time again! lol
No problem!! Keep at it and hopefully we will get it working to your satisfaction, it's sometimes hard to figure out what previous owners have done and why.
