The way to confirm this is to try and adjust the intermidiate band to 10 ft lbs,if the 10 ft lbs can not be achieved then the band is broken and would need to be replaced. The transmission would have to be removed to do this. If the band is not broken then once you achieve the 10 ft lbs you would adjust the band by turning out on the adjuster 2 full turns. If this does not solve the concern then the problem may be the servo piston(this applies the band) bore is worn and this requires a sleeve installed into the case to correct this.

This article supersedes TSB 03-25-4 to update the description for labor operation "B". There have been no changes made to the TSB procedure.
Some 2002 Explorer/Mountaineer vehicles built prior to 3/4/2002 with 5R55W transmission, may exhibit no 3rd gear or slipping 2-3 shift with diagnostic trouble codes (DTCs) P0733 and P0745 present. This may be due to a broken intermediate band.
If the conditions described are verified:
Per Procedure "B", if a broken band is found replacement of both the OD and intermediate bands and pistons will be necessary. However, only an inspection of the direct clutch drum may be necessary. The drum should not be replaced unless damage is found.
Using the following procedure, replace the bands and servos. Inspect the direct clutch drum and replace ONLY IF DAMAGED.
Here is a tsb on repairing the servo bore.
Some 2002-2009 Explorer, Mountaineer, 2007-2009 Explorer Sport Trac, 2002-2006 Lincoln LS, 2005-2009 Mustang, 2002-2005 Thunderbird and 2003-2005 Aviator vehicles equipped with a 5R55S, 5R55W, and 5R55N transmission may experience shifting concerns. A loss of 2nd, 3rd and 5th gear, may have overdrive band or intermediate band failures due to servo pin case bore wear causing reduced apply pressure.
Follow the Service Procedure steps to correct the condition.
For transmissions that have been determined to require an overhaul or rebuild and the overdrive band or intermediate band have excessive wear or burned/damaged band friction material, the cause maybe excessive servo pin case bore wear generally found on higher mileage vehicles, usually accompanied with incorrect ratio diagnostic trouble codes (DTCs), condition becomes worse when hot. (Figure 1)Figure 1 - Article 09-12-12
In our instructions, when we refer to the overdrive bore, we are talking about the smaller bore located closest to the bell housing. When we refer to the intermediate bore, we are talking about the larger bore located next to the line pressure tap.
Inspect and repair the worn-damaged transmission case servo pin bore utilizing the Rotunda Tool 5RW Master Kit part number NRL5RW servo pin bore repair system (1-800-768-8632 option 6).

Correctly installed bushings will be flush inside of case. (Figure 9) Figure 9 - Article 09-12-12
The 9/16" and 5/8" reamers require typical maintenance and cleaning of aluminum build up on the cutting edges to help provide optimum bushing installation and increased tool life.
After bushing installation, thoroughly wash the case before rebuilding transmission.
Both of these can be rather expensive. The band would the most inexpensive one but again the transmission would have to be removed and disassembled. Depending on how many miles you have on this vehicle you may need to consider an actual overhaul which may cost around $1900 on this vehicle. Now if the bore is worn then you would need to research price here because you may now get into the 2200 to 2300 range and since repairing your trans would only carry a 12 month/12000 mile warranty.You can install a reman assembley for pretty close to this price and it would carry a 3yr 100k warranty.
