47re engine braking ?

47re engine braking ?
I rebuilt a 47re for my cousin everything went smoothly (only my 4th trans rebuild so i'm green at this).
The valve body is an after market valve body with a transgo shift kit from Central Valve Body, It never has shifted hard maybe alittle firmer than stock, I drilled the 1-2 and 2-3 holes out on the plate and for the lock up.
I filled it up drove it rechecked and topped it off, Drove it 22 miles, it shifted really firm but not harsh, and lock up was more firm, Didn't have any flares in any of the gears.
Now the problem which might not be a problem, When running 60 mph in od and lu if you back out of the throttle the rpms drop to 1000 and you will slowly loose speed if you ever so slightly keep throttle pressure it will slowly loose speed and you will still have engine braking, Also I forgot the return spring for the tv cable, I never had a chance to adjust the tv cable or anything either. Could it be a band issue also??? I adjusted them per the transgo shift instructions, snug then back off how ever many turns (2 for the front i think and 3.5 for the rear??)
what are your guys thoughts, I left it down home because i didn't want to drive it the 3 hours to my place like that, so i'll be working on it around the 18th.

the only vehicle i ever had a problem with adjusting the bands, and from what i could tell, if too tight it will stop (abruptly in my case) loose and things were slow to shift out, if only done a handful and most were older gm products...good luck and i'd bet it involves the tv cable

At idle the converter clutch disengages and it simply coasts down in speed. With a light throttle it can keep the converter clutch locked and use what little engine braking it as.
Diesels are not throttled--as in air valves in a carb or gas engine-- so they coast farther.
you are describing a normal situation.
