My transmission problems continue! My '06 E350AWD has had the following work performed recently in the hope of solving this problem: new Battery, replaced Shifter Assy., new Conductor plate Filter and Shell 134.

When I drained the oil I failed to see any metal chips, etc. The Fluid was clean & the magnet in the pan was also clean. I've had several threads on this topic and I will try to compress everything When I pulled the Codes I found the following: P0715 wich is an "irregular signal coming from the input/turbine speed sensor in the transmission".

Where is the Input Speed Sensor? Would replacing this Sensor fix my problem?

TIA!
