- 2005 Explorer XLT AWD
I am posting this to help anyone experiencing the symptoms my 2005 4.6L AWD Explorer had when I bought it.
I got the Explorer used at 97K miles with no history of the vehicle.
I noticed at around 100K miles it appeared to slip in 5th.
I researched this and found the SK5R55W/S Shift kit online and installed the shift kit.
I reassembled everything and on the test drive noticed a complete loss of 2nd gear in "Drive".
I verified fluid level was correct at 120*F and Valvoline MERC-V was used.
List of symptoms:
1. Total loss of 2nd gear on Up or Downshift in "DRIVE"
2. 2nd gear works fine when transmission is in manual "2".
3. 2nd gear does not slip when in manual "2", even at WOT under load.
4. 5th gear / OD engages with a Bang and is delayed, won't go in until throttle is lifted. Does this EVERY shift into 5th.
5. 2nd gear loss at times in Manual "2" when transmission is warm, won't engage at all and acts like it is in neutral.
6. No transmission codes or pre-codes.
7. Hard/Harsh Engagements for Drive and Reverse
8. Vehicle Lunges when braking /stopping (appears to be a hard downshift into 1st gear below 10 mph)
9. OD off button at times won't cancel OD.
10. Downshift under WOT from OD to 4th high rev.
11. No metal in pan or burned fluid
12. Occasionally stalls when coasting down a hill in "DRIVE"
What fixed it:
1. The Shift kit improved OD hold and does not slip, this may also be due to the excessive wear in my old valvebody.
2. Tightened the Bands to 120in/lbs and back out 2 turns.
3. 8-9 Quarts of MERC-V Transmission Fluid
4. New Valve Body with shift kit
5. New Solenoid Pack
I tore the old Valve body apart and it had several parts that were worn and sticking.
The Solenoid Pack was most of the problem in my case.
The transmission shifts like new now and has no slipping, delayed engagements or lunging when braking like before.
I am posting this to help anyone working on the 5R55S in a high mileage vehicle and to prevent someone else from going into the transmission multiple times like I did to get it fixed.
If you have ~ 100K miles and are having the same issues mine did, replacing the valve body and solenoid pack and installing the Shift kit may be all you need to fix it. I was told by several shops to just rebuild or install a Remanufactured transmission.
