When the feed limit valve bore wears, a loss in a pressure rise and shift
solenoid oil will follow causing the above codes and friction burn-up.
With slight wear at this area, PO735 ratio error 5th gear is common when hot.
If the fluid is clean, consider fixing VB in the car.
Step 1. Remove and discard the original Feed Limit Valve and Spring.

Step 2. Hold VB down flat on the bench as shown, with a 3/8 drill (cordless works great) AND OIL, guide reamer into the spring pocket area. Begin light cutting on the outer bore (.001). This will become the guide for the actual valve area where the cutting gets heavier. Clean VB. Install NEW valve making sure valve slides freely in the bore before assembly. Never use Ream dry!
Step 3. Install new Valve, Orange, Red, and White springs.

99-02 BMW had different diameters Low/Rev & 2nd pistons at this time no seal
protectors are available.
Check bore for wear. Place the
valve where the two skinny lands line up at the arrow and wiggle valve. If
wear is bad enough to catch the valve, it will stick in use causing no
movement.
The new PR valve has repositioned lands and an internal exhaust circuit so
both ends of the valve will be supported at all times.
New Valve is fixed even with substantial bore wear!
To Install. Remove and discard the original PR valve and innerspring.
Place new PR valve in bore and stroke in and out. If you can feel it catch on
a ridge just tap it gently side to side till it’s free. Assemble New PR Valve,
Spring Seat, and New ORANGE inner spring as shown.
