Is this normal with a 727

[thepaintshop]

I just got this 67 Plymouth it has 440 with 727 auto. It holds first gear till about 30mph before it goes into second and about 50mph before it goes into 3rd. Is this normal I don't know if it has a shift kit in the trans or not. Thanks for the help.

Does it have kick down rod/ linkage from the carb on drivers side??If so,it needs to be adjusted:yes:

It has the kick down rod. where is the adjustment at the carb or at the trans? And which way does it need to be adjusted.
Thanks

The adjustment is at the carb. it needs to be adjusted so that the kickdown rod is fully engaged when the carb is wide open. it sounds like the rod is too far engaged. It may be best to get some help if you can.

I think the shift points should be 15 and 25 under normal acceleration.

Found the adjustment got it where its shifting at around 20 for 2nd and 40 for 3rd. Their isn't anymore adjustment in the rod it has bottom out. DO I need to trim a little off the rod or does these shift points seem correct?
Thanks for all the help

The unofficial way to set it is to have the throttle pressure valve linkage (aka kickdown linkage) right at fully open when the carb is at WOT. From here, make adjustments to get the shift points where you like them. Thread in the end at the carb linkage to create a little bit of space between the end of the slot and the carb stud when at WOT to bring the shift points down.

See if you can adjust the rod that runs down the backside of the motor to gain some room up top to continue adjusting. If this doesn't work, then you may have to trim up the rod, but if it were me, I'd try to exhaust other options first before cutting up original linkage (if you're in to keeping it this way).
