I have a 64 727 with the buttons and a TCI 2500 stall. The trans has now started to hesitate on the 2 3 shift. It will hesitate whether I shift it or let it shift.
I have recently played with the kickdown rod to get full throttle with the 2x4 intake, but Im positive its all the way back.
Another question, are these worth rebuilding. Ive done the th400 conversions for some people, but not on a early car. How does the 400 fit in the trans tunnell on early cars.

The car is street strip with 400 hp or so. Offy dual 4 intake with holleys. Yes on the trunion. My plans for the car are open.

The 727 should be fine , just have to be careful as those early pushbutton cases aren't too easy to find.

Thanks Hutch. Is this something that can be fixed in the car or is it time. It has been rebuilt before.

Changing the intake / carb messes with the kick down geometry and is hard to get it back again.

Changing to a reverse manual eliminates the kick down linkage and can be run on the street. The Torque Flight is a great transmission and there is no need to swap to a TH400 unless HP becomes a issue.

The trunnion is weak, but if it is working at your HP level, I wouldn't change it. 1965 push buttons models had a slip yoke but are almost impossible to find and could be very expensive to obtain.

I can build you a push button valve body with or without trans brake, with latest technology, and will completely eliminate the 2/3 overlap,

Give Keith at www.727specialist.com a call, he can fill you in on the details.

We have had great results with our 727 reworked by Keith (727 Specialist) with a 900HP on gas & 1400HP on NOS setup running in a all Mopar car 7.82/172mph. Why change to a TH400 with all the modifying that has to be done with the swap. Put the $$$ into your own trans.
Good Luck
