727 shifting problem

[68tripleblk]

Hey guys need some help here; first the back story: My 727 was working perfect then I decided to add a Turbo Action 3000 stall converter and put my 3.91's back in. Did that and road tested great, then I ended up blowing the rear servo backing out of the garage, frustrated and thinking it was my reverse band I sent out my spare 727 to be rebuilt with a Transgo stage 2 shift kit to a local guy.

So when I get the tranny back and installed it is shifting weird in drive shifts from 1-2 only after you lift the throttle at about 5 grand!! then 2-3 shifts at about 4000 and no downshift (either passing gear or slowing down)but will if you manually pull it down a gear or two. Now in manual it has a huge delay and sometimes won't shift from 1-2 unless you go to drive instead of 2nd not very impressive when you hit the rev limiter thank God for MSD  I have played with kickdown (lokar cable) to no avail (worked fine with old trans). I am going back to see tranny guy but would like to know Mopar thoughts first because this guy does mostly chevy work.

Thanks
Jamie

sounds like either govenor weights sticking or valves sticking in the valve body

need to put a gauge on the gov pressure port

First, disconnect the Lokar cable at the transmission lever and force the lever full forward then take it for a test drive; if it shifts OK at part throttle the problem is in the TP cable.

If it still won't upshift normally, hook up a gauge to the governor pressure test port; if the pressure is more than 2 psi at a standstill in Drive the governor is the problem. If the governor pressure is normal you have a sticking shift valve.

It was the blasted passing gear!!!  Put a spring on down below and put a pile of slack in up top and it now shifts!!!  Now I need to fine tune it.  Thanks for all the help.
