This is very true, often transmission shops do a "soft parts" rebuild, this will almost ensure trans will fail within 2 years, often just over 1 year(warranty).
From Gloria Roosen:
"When having an A4LD rebuilt, there are a couple of things that you need to make sure of. First and foremost, do not let a shop do a soft parts fix only
(clutches, servos, and bands).
This will almost ensure that you will have another repair needed right after the 1-year warranty is out. Other things you want to have replaced are: forward one-way clutch (always), overdrive drum (stamped tin, replace if out of round or heat damaged), pump (Ford only
, rebuilds are prone to failure), and the converter (get the better converter with the improved lock-up clutch and brazed fins). Also, get references from the shop and call the people."
A little history, the A4LD is the father of the 4R44E/4R55E and 5R44E/5R55E, basically same transmissions but they "split" gears to add an extra ratio, making a 4-speed a 5-speed, very clever.
I think trans starts in 1st then shifts to OD as second gear, 1st + OD = 2nd, then 3rd, 4th and OD
Rebuilt trans can be as good or better than new with upgrade parts, but rebuilder HAS TO USE the parts, soft fix just isn't worth the risk.
