So I had this transmission rebuilt by a guy a trusted friend reccommended. The trans shifted fine but the overdrive was slipping.

I got it back and now I won't shift into third.

FIST, SECOND REVERSE no issue.

No concerning noises.

The kickdown is adjusted as specified, I've even tried just unhooking it completely as a test, no luck.

Fluid filled to the spec (like 10 quarts) that the book says for a full fill with new converter.

Can anyone give me anything else to do?

I've read the front band adjustment can possibly cause this.

Any help appreciated.

When it won't go into 3rd, does it stay in 2nd or go neutral?

Most likely a governor problem, only a gauge will tell. Could also be a weak front clutch problem...front clutch is also used in Reverse but at a much higher pressure

Can you explain better not going into 3rd ??? Does it just wind up without making a shift staying in 2nd , or is the engine RPM racing up to limit ?? The way a 727 shifts is in all forward gears the rear clutch is always applied , this is first , 2nd the front band stops the front drum from spinning , 3rd is the front band releasing and the front clutch pack applying , if the front clutch pack doesn't apply the trans is back in 1st, the front band is not going to reapply until the vehicle slows enough for the governor circuit to make the front band reapply ... aka downshift.

I have never heard of the front band adjustment not allowing 3rd to happen , these shifts are hyd. controlled , if the valvebody sends fluid to the front clutch to apply and the band is so tight it's not releasing the vehicle is going to nose over like you stepped on the brakes.

Not necessarily...if there isn't enough governor pressure to move the 2-3 shift valve, it will stay in 2nd indefinitely. The only way it will drop back to 1st is if the 2-3 shift valve does move and releases the band but doesn't apply the clutch. Need to wait for OP's reply to see which it is.



Normally, when slowing to a stop, the trans drops from 3rd directly to 1st without applying the front band. Applying the front band on decel would cause an uncomfortable lurch.

Reason why we need more clarification.

From my own experience with my Ram pickup with a slipping front clutch going back into 1st is what was I figured out was happening , it would shift , rpm drops for a second then right against the rev limiter , let off the throttle and it's back in third.

I didn't realize that it skipped 2nd on the downshift , thanks for the clarification. The shift to 1st on decel happens when you pretty much come to a stop , otherwise you would probably get a lurch ???
