Rebuilt 727 Tranny

[mopar thunder]

My wife had her 727 rebuilt and has had it back for 4 days now. Should a rebuilt act like this?  First start up after a warm up it shifts hard and 2-3 is up around 3800-4000rpm. Then after it shifts a few times like that sometimes it gets stuck in 2nd gear and never down shifts past that. After about 5 minutes of driving it seems to shift fine although the shifting points are not optimum I believe. Any thoughts? Apparently the torque converter was rebuilt to. I was told they sent it out. I believe that is an 11" converter...... but not positive.

Take it back...

I agree take it back, something is going on, get on it before it gets worse..

In all my years I have only had 1 727 built properly , it was set up perfectly with the governor etc , if you held it to the floor it would shift right at redline , lift a little & it would shift earlier , it had the right converter stall speed , you would not think it would be that hard to do but ....

It is going back this week. She wanted to take it out but I said wait till you take  it back so they can't say we did anything. It should be n easy fix just to rebuild by a reputable tranny guy but........ as I well know things happen. See my fuel line post.

Most likely fixable without pulling the transmission out. I'm no trans technician but 727's are pretty darn easy to rebuild if you follow the factory manual, make a few measurements and keep things clean. I bought some parts off Pat Blais when I built the 65 trans for my 64 and that was the best one I ever put together after listening to what Pat told me to do for clearances and pressures.
