2005 f-150 xlt won't go foward and is showing codes:P0720 and P2106. What are some things to check?

Asked by Nov 24, 2014 at 08:39 PM about the 2005 Ford F-150 XLT

Question type: Maintenance & Repair

It was a sudden thing that happened. There was no early signs that anything was going out. almost like a light switch effect. The truck has 133,195 miles and has run great up until this point.  I reset the codes and they stay off until I put the brake on and shift into drive while taking the rpms to about 2,000. Then it will shutter and the code lights come on. The"O/D off" light flashes in the cluster also while this is preformed. No leaks, fluid is perfect, and no whine or grind of any kind. Its got to be electronic I'm thinking. Any suggestions?

I know nothing about trannys, but I put your question to my tranny guy who owns a shop. The 0720 cold would indicate a possible problem with the output speed sensor. A sympton for the tranny is the TCM is not receiving the proper voltage. It could be the sensor itself or a wire. Suggest it be checked out by a tranny shop who has the proper scanning equipment
